Overview of Polling and Thresholds

Managing Groups, page 17-1, describes how Group Administration organizes devices, device interfaces, and device ports into different groups. The Common Services system-defined groups include groups such as Cisco Interfaces and Module, Content Networking, Routers, Voice and Telephony, and so forth. These groups have specific polling and threshold settings, while the Broadband Cable device type has different polling and threshold settings. Because a device can belong to multiple groups, the device uses the polling and threshold settings of the overriding group.

The Operations Manager Polling and Threshold function creates its own corresponding groups based on Common Services and Operations Manager groups:

•Polling groups that determine how often group members are polled for data.

•Threshold groups that determine acceptable levels of performance and utilization for group members.

When group objects are polled and any object's data shows that threshold values have been exceeded, or values have fallen below acceptable levels, Operations Manager generates the appropriate events.

Operations Manager is configured with default settings for polling parameters and threshold values. You can use the default settings, edit them, and restore them to default settings at any time.

In many cases, it might be acceptable to use the default settings for polling parameters. However, depending on how important a device group is, you can increase or decrease the polling interval to accomplish either of the following objectives:

•Minimize the impact on the polled devices

•Enhance the resolution of the collected data

In addition, you can enhance the performance and utilization of devices by adjusting thresholds, taking into account the following information:

•Location of the devices in the IP fabric

•Resource constraints

Which Settings Are Applied to Devices, Ports, and Interfaces?

Every device, device port, and device interface belongs to at least one system-defined group; in fact, they can belong to several. When a device belongs to several groups, Operations Manager uses the settings of the overriding group. The overriding group is the highest priority device group to which the device belongs. For more information, see Setting Priorities which explains how to change group priorities and lists default group priorities.

Which Polling Settings Are Applied?

You can set and apply polling parameters to device groups (not for individual devices). When a device is polled, its ports and interfaces are also polled; therefore, port and interface polling is controlled at the device level.

Every device belongs to at least one system-defined device group. See Working with System-Defined Groups, page 17-3, for information about how devices are assigned to system-defined groups. If a device belongs to more than one group, Operations Manager uses the polling settings of the overriding group (with the highest priority, as described in Setting Priorities).

Which Threshold Settings Are Applied?

You can set and apply threshold parameters to device, interface, and port groups. When a device is polled, Operations Manager compares the new data against the threshold settings. If a threshold value has been exceeded, or a value has fallen below acceptable levels, Operations Manager generates the appropriate event.

If a device, port, or interface belongs to more than one group, Operations Manager uses the threshold settings of the overriding group (the group you determine to have the highest priority, as described in Viewing the Overriding Group—Examples).

Setting Priorities

---

Note A device group can have different overriding polling and threshold groups.

---

You can set the priority for each of the following:

•Device polling groups

•Device threshold groups

•Interface threshold groups

•Access port threshold groups

•Trunk port threshold groups

---

Step 1 Select Administration > Polling and Thresholds > Priorities. The Setting Priority: Queue page appears, displaying the groups in priority order.

Step 2 Select the radio button that corresponds to the group type, one of the following:

---

Note A device can have different overriding polling and threshold groups.

---

•Polling groups:

–Device Polling Groups

•Threshold groups:

–Device Threshold Groups

–Interface Threshold Groups

–Access Port Threshold Groups

–Trunk Port Threshold Groups

Step 3 Rearrange the groups according to your preference (the closer the group is to the top of the list, the higher its priority):

a. Select a group.

b. Move the group up or down using the Up and Down buttons.

Step 4 Click Save. The changes are now saved in the database.

---

Note The changes do not take effect until you apply them to Operations Manager. See Applying Changes.

---

---

Because devices, ports, and interfaces can belong to multiple groups, Operations Manager uses the highest priority group to which the device belongs to determine which polling and threshold parameters to use. Operations Manager prioritizes groups as follows, in descending order of priority:

•Access and Trunk Port Group Priorities for Thresholds, Table 18-1

•Interface Group Priorities for Thresholds, Table 18-2

•Device Group Priorities for Polling and Thresholds, Table 18-3

---

Note To find the overriding group for a device, you can select any device group to which the device belongs and view a Polling Parameters report or a Thresholds report for the group.

---

By default, Operations Manager gives highest priority to Access Port Groups and Trunk Port Groups, listed in Table 18-1.

1 A device can have different overriding polling and threshold groups.

For additional information, see the following topic:

•How Can I Set Parameters for a Device, Interface, or Port?

Viewing the Overriding Group—Examples

The Polling Parameter and Threshold reports provide information on the overriding groups for all devices in a specific group. Locating the overriding group for a port or interface is a bit more complex, as described in the following procedures.

Viewing the Overriding Polling or Threshold Group for a Device

Use the Polling Parameter report or Thresholds report to identify a device's overriding group.

---

Step 1 Select Administration > Polling and Thresholds.

Step 2 Do one of the following:

•To view the overriding polling groups, select Polling Parameters.

•To view the overriding threshold group, select Thresholds.

---

Note A device can have different overriding polling and threshold groups.

---

Step 3 Select a device group that the device is a member of and click View. The appropriate report opens. Locate the device in which you are interested, and look at the Overriding Group column.

---

Viewing the Overriding Threshold Group for a Port or Interface

---

Step 1 Select Administration > Polling and Thresholds.

Step 2 Consider the port or interface type and check the appropriate system-defined group for that type, and select Thresholds.

Step 3 Select the port or interface group and click View.

For example, if you think an interface is in the 10MB-100MB Ethernet interface group, you would select Thresholds, choose that group, and click View, and Figure 18-1 would open.

Figure 18-1 Viewing the 10MB-100MB Ethernet Interface Group —Step 1 (of 2)

Step 4 Click View Interfaces. A complete list of interfaces is displayed. See Figure 18-2. (If you were searching for a port, the link would say View Ports.)

Figure 18-2 Viewing the 10MB-100MB Ethernet Interface Group —Step 2 (of 2)

a. If the interface or port appears as a member, that group is the overriding group. (Ports and interfaces are only listed as members in the overriding group.)

b. If the interface or port does not appear, repeat this process for all subgroups of port and interface groups until you locate the port or interface.

---

Enabling and Understanding Polling for Route Lists and Route Groups

Operations Manager can calculate route group utilization and route list utilization for Cisco Unified Communications Manager clusters. However, you must first enable voice utilization polling for each cluster that is of interest to you. Repeat this procedure for each such cluster.

---

Step 1 Select Administration > Polling and Thresholds > Polling Parameters.

Step 2 Expand the Cisco Unified Communications Manager or Clusters group to see the list of specific clusters that Operations Manager is managing.

Step 3 Select the cluster for which you want to enable voice utilization polling and click Edit. The Polling Parameters: Edit dialog box appears.

Step 4 Select Voice Utilization Settings from the Parameter Type list. Cluster Utilization Settings appears in the parameter table.

Step 5 Select the Polling Enabled check box.

---

Note For information about other settings on the Polling Parameters: Edit dialog box, see Editing Polling Parameters.

---

Step 6 Click Apply to save the settings, close the Polling Parameters: Edit dialog box, and apply changes to the system. When a confirmation dialog box appears, click Yes. For more information, see Understanding what Happens when You Apply Changes.

---

A route list, defined in a Cisco Unified Communications Manager cluster, contains route groups; route groups contain gateways. Operations Manager polls these gateways, gathering utilization statistics, when voice utilization polling is enabled for the cluster. From the utilization statistics, Operations Manager calculates the route group utilization and route list utilization. As a result:

•You can launch performance graphs from the Service Level View for the route lists in a cluster, the corresponding route groups, and the gateways in a route group. For more information, see Viewing Performance Monitoring, page 2-17.

•You will be alerted when route list or route group utilization exceeds a threshold or becomes completely utilized. For more information, see Route List Utilization Threshold and Route Group Utilization Threshold.

How Can I Set Parameters for a Device, Interface, or Port?

There are several ways in which you can control the parameters for a device, interface, or port. Polling and thresholds are always applied on a group level, not on a specific device, port, or interface level.

---

Note Be careful when you change settings for a system-defined group. Your changes will affect the settings of all devices in the group.

---

---

Note To apply settings to a device or component that belongs to multiple groups, make sure the group with the desired settings is the overriding group (has the highest priority), as described in Setting Priorities.

---

To configure polling and threshold settings for a device:

•Adjust the polling and threshold settings for any system-defined group to which the device belongs (and verify the overriding group, if applicable). This changes the settings for all devices in that system-defined group.

•Create an Operations Manager (OM@server) user-defined group and edit it. Apply the desired polling and threshold settings to the group and verify the overriding group. In this way, you can create a group of specific devices in which you are interested, and specify settings for them.

To configure polling on interfaces and ports:

•Adjust the polling settings defined by the Operations Manager (OM@server) system-defined group (and verify the overriding group, if applicable). This changes the polling settings for all interfaces and ports on devices in that system-defined group.

•Create a user-defined group and edit it. Apply the desired polling and threshold settings to the group and verify the overriding group. In this way, only the ports and interfaces on specific devices are affected.

To configure thresholds on interfaces and ports:

•Adjust the threshold settings defined by the Operations Manager system-defined port or interface group (and verify the overriding group, if applicable). (Make sure the port or interface belongs to that group, as described in Viewing the Overriding Threshold Group for a Port or Interface.) This changes the threshold settings for all interfaces and ports in that system-defined group.

•Create a user-defined interface or port group and edit it. Apply the desired threshold settings, and verify the overriding group. In this way, only the ports and interfaces on specific devices are affected.

For additional information, see the following topics:

•Editing Polling Parameters

•Editing Thresholds

Updating Polling Parameters and Thresholds

Operations Manager is preconfigured with default settings for polling parameters and thresholds for each system-defined device, port, and interface group. Optionally, you can change them. The following steps describe the basic process for updating polling parameters and thresholds.

	Task	Procedures
Step 1	Enable or disable polling for selected polling settings or parameters; change polling parameter values for device, port, interface, or application groups contained within the following: •Operations Manager (OM@server) system-defined groups and user-defined groups •Common Services (CS@server) system-defined group Note At any time, you can go back to Operations Manager default values for polling.	Editing Polling Parameters Restoring Default Polling Parameters
Step 2	Enable or disable thresholds; change threshold values for device, port, interface, or application groups contained within the following: •Operations Manager (OM@server) system-defined groups and user-defined groups •Common Services (CS@server) system-defined group Note At any time you can go back to Operations Manager default threshold values and threshold settings.	Editing Device Group Threshold Settings Editing Access Port, Trunk Port, and Interface Group Threshold Settings Customizing Threshold Settings Restoring Default Thresholds
Step 3	Change the default priority for the following: •Device polling groups—Place device groups in priority order for polling. •Device threshold groups—Place device groups in priority order for thresholds. Note Device groups can have different overriding polling and threshold groups. •Access port threshold groups—Place access port groups in priority order for thresholds. •Trunk port threshold groups—Place trunk port groups in priority order for thresholds. •Interface threshold groups—Place interface groups in priority order for thresholds.	Setting Priorities
Step 4	When you are done with all changes, if possible, select a time of low activity on the network to update the IP fabric with these changes. The new values will not be used until you apply your changes.	Applying Changes

Selecting Groups

The first thing you must do when you use polling and threshold options is select a group for which parameters exist. Generally, this is a group that does not contain subgroups.

Table 18-4 lists groups in the order in which they are displayed in the group selector and notes whether applicable parameters exist for the group. The group selector you see might not display all of the device groups listed in Table 18-4; device groups are displayed when they have members.

Table 18-4 Device Groups as Displayed in the Device Selector

•Editing Polling Parameters

•Viewing Thresholds

Managing Polling Parameters

Most port and interface polling is controlled at the device level. However, you can set polling parameters for voice ports and voice interfaces for some voice-enabled device groups. For a list of device groups and related polling parameters, see Parameter Types, Device Groups, and Polling Settings.

From the Polling Parameters page, you can perform any of the following tasks:

•Viewing Polling Parameters

•Editing Polling Parameters

•Restoring Default Polling Parameters

Viewing Polling Parameters

When you view polling parameters for a device group, you can see the devices that are members of the device group, and see the default as well as current values for the polling parameters. Devices that belong to multiple groups use the polling settings of the overriding group. Interface and port polling is controlled at the device level; in other words, switches have a specific polling setting, and that setting determines when the switch ports are polled.

---

Note If Operations Manager is set to ACS mode for authentication, Cisco Secure ACS may limit the devices you are permitted to view when you generate a Polling Parameters report. For more information, refer to Device-Based Filtering, page 20-23.

•Printing Displays or Reports, page 1-19

Editing Polling Parameters

When you edit polling parameters, you edit settings that are associated with device groups, not with individual devices. When you have finished all changes to polling parameters (and thresholds and priorities), apply all changes. For more information, see Understanding what Happens when You Apply Changes.

---

Step 1 Select Administration > Polling and Thresholds > Polling Parameters.

Step 2 Select a device group for which you can set polling parameters. Generally, this is a device group that does not contain subgroups. (For more information, see Selecting Groups.)

Step 3 Click the Edit button. The Polling Parameters: Edit page appears, displaying the following information.

GUI Element	Action/Description

Polling Enabled	To disable polling for this setting, deselect this check box. To enable polling, select it. Note Selecting or deselecting the Polling Enabled check box in the table heading causes all Polling Enabled check boxes to be correspondingly selected or deselected.

Step 5 To save the settings, do one of the following:

•Click Save; your changes are saved in the database. Click Cancel; the Polling Parameters: Edit dialog box closes. Your changes will not go into effect until you have applied them. See Applying Changes.

•Click Apply to save the settings, close the Polling Parameters: Edit dialog box, and apply changes to the system. When a confirmation dialog box appears, click Yes. See Understanding what Happens when You Apply Changes.

---

Understanding what Happens when You Apply Changes

After you adjust polling and threshold settings, you must apply changes to have Operations Manager start using your changes. The following explains the difference between saving your changes and applying your changes.

When you save changes, Operations Manager performs the following tasks:

•Sets the polling and threshold settings in the selected group.

When you apply changes, Operations Manager performs the following tasks:

•Recalculates group membership, based on group priority.

•Uses the new polling and threshold settings to gather information from the devices.

You must also apply changes after resuming a device, so that Operations Manager will begin polling the device depending on the appropriate settings.

You can apply changes by selecting Administration > Polling and Thresholds > Apply Changes. You can also apply changes by clicking Apply on the Polling Parameters: Edit page or the Thresholds: Edit page.

Restoring Default Polling Parameters

You can restore all parameter settings for a device group to default values using this procedure. If, instead, you want to restore only a few functions or settings, see Editing Polling Parameters.

Before You Begin

To review default polling settings before you apply them, view the Polling Parameter Summary for the device group. See Viewing Polling Parameters. Current settings along with the default settings are displayed.

---

Step 1 Select Administration > Polling and Thresholds > Polling Parameters.

Step 2 Select a device group for which you can restore polling parameters. Generally, this is a device group that does not contain subgroups. (For more information, see Selecting Groups.)

Step 3 Click the Revert to Default Settings button. A confirmation dialog box appears.

Step 4 Click Yes.

---

Note The settings are stored in the database, but not yet applied to the IP fabric. See Applying Changes.

Parameter Types, Device Groups, and Polling Settings

This section provides information on polling settings for each parameter type:

•Data Settings—Polling

•Voice Health Settings—Polling

•Voice Utilization Settings—Polling

Data Settings—Polling

Data settings enable you to poll for device reachability, environment, ports and interfaces, and processor and memory utilization. Table 18-5 lists all data settings and polling intervals for each setting.

Table 18-5 Data Settings—Polling Settings and Default Polling Intervals

Data Polling Settings	Intervals (in seconds)	Usage Notes
Access Port Settings	•30 minimum. •3600 maximum. •1200 default —You can adjust the default polling interval in 1-second increments.	To enable polling for Access Port Settings, you must enable polling for Connector Port and Interface Settings. The same timeout and retry values are used for Access Port Settings and Connector Port and Interface Settings. When you update the timeout and retry value for either of these settings, Polling updates the values for both.
Connector Port and Interface Settings	•60 minimum. •3600 maximum. •240 default —You can adjust the default polling interval in 1-second increments.
Environment Settings		Environment Settings and Processor and Memory Utilization Settings are not available for all device groups. Some voice-enabled device groups (noted in Table 18-6) have similar settings available for Voice Health Settings parameter type.

Note•Polling for voice-enabled ports and interfaces is controlled by voice health settings.

•Polling is disabled by default for user-defined groups. To enable polling for user defined groups, see Editing Polling Parameters.

---

Voice Health Settings—Polling

Voice health settings control polling for voice-enabled devices, ports, interfaces, and Cisco Unified Communications Applications. Data that is collected includes Cisco Unified Communications Manager cluster connectivity and processor and memory utilization on Media Convergence Servers (MCS) and on voice gateways. Voice health settings default polling intervals (in seconds) are:

•Minimum:

–240—For clusters in the Cisco Unified Communications Manager or Cluster device group.

–30—For all other device groups.

•Maximum—3600.

•Default—240. You can adjust the default polling interval in 1-second increments.

Table 18-7 lists device groups and the voice health settings that are applicable to them.

Voice Utilization Settings—Polling

Voice Utilization Settings control performance polling. Performance polling collects utilization and capacity planning data from Cisco IOS gateways, gatekeepers, SRST devices, Cisco Unified Communications Manager, Cisco Unified Communications Manager Express, Cisco IP Contact Center, Cisco Unity, Cisco Unity Connection, and Cisco Unity Express. Performance polling is disabled by default.

When performance polling is enabled, Operations Manager collects performance and capacity data that:

•Is accessible from monitoring dashboards in the form of performance graphs; see How to Use Performance Graphs, page 7-1.

•Is also stored in data files on disk for further analysis; for information about data files, see Performance Polling Record Formats, page J-2.

•Is measured against Voice Utilization Settings thresholds. When thresholds are violated, Operations Manager generates events related to performance and capacity problems in an application, on an interface, or on a device; for example, high utilization of ports, channel, and resources of a device.

For information on enabling Voice Utilization Settings, see Editing Polling Parameters.

Voice Utilization Settings default polling interval values (in seconds) are:

•30 minimum

•3600 maximum

•240 default—You can adjust the default polling interval in 1-second increments.

Table 18-8 lists device groups and the Voice Utilization Settings that are applicable to them.

Managing Thresholds

From the Thresholds page, you can perform any of the following tasks:

•Viewing Thresholds

•Editing Thresholds

•Restoring Default Thresholds

For a list of device groups and related threshold settings, see Parameter Types, Device Groups, and Threshold Categories.

Viewing Thresholds

You can view the thresholds that are associated with device groups, trunk port groups, access port groups, and interface groups. Because the numbers of ports and interfaces can be very large, the Thresholds report provides a link through which you can launch a separate page that lists all the ports and interface members of the group. Optionally, you can save the Thresholds report in a comma separated value (CSV) file.

If the Operations Manager server is using ACS mode for authentication, Cisco Secure ACS may limit the devices you are permitted to view when you generate a Thresholds report. For more information, refer to Device-Based Filtering, page 20-23.

---

Step 1 Select Administration > Polling and Thresholds > Thresholds.

Step 2 Select a device group for which you can set thresholds. Generally, this is a device group that does not contain subgroups.

Threshold Definitions for Data Settings

This section contains threshold definitions for the following Data Settings threshold categories:

•Disk Usage and Virtual Memory Settings (Data Settings)

•Environment Settings (Data Settings)

•Generic Interface/Port Performance Settings

•Interface/Port Flapping Settings

•Backup Interface Support Settings

•Dial-On-Demand Interface Support Settings

•Processor and Memory Settings (Data Settings)

•Reachability Settings

Disk Usage and Virtual Memory Settings (Data Settings)

---

Note For voice-enabled devices, see Disk Usage and Virtual Memory Settings (Voice Health).

---

Disk Usage and Virtual Memory Settings monitors the performance of disk usage and virtual memory elements. Events such as high disk utilization and high virtual memory utilization are controlled by these parameters.

Drive Array Faults Threshold

Count of drive array faults.

Free Hard Disk Threshold

Minimum amount of hard disk space, expressed as a percentage of the total hard disk memory.

Free Memory Threshold

Minimum amount of free virtual memory, expressed as a percentage of total virtual memory.

Environment Settings (Data Settings)

---

Note For voice-enabled devices, see Environment - Temperature Sensor Settings (Voice Health Settings).

---

Relative Temperature Threshold

Indicates how close the current temperature value can be to the value that triggers an emergency shutdown, expressed as a percentage of the emergency shutdown value. For example, if the shutdown temperature is 50° C and the Relative Temperature Threshold is 10%, the OutofRange event occurs if the temperature exceeds 45° C.

Relative Voltage Threshold

Indicates how close the current voltage value can be to the value that triggers an emergency shutdown, expressed as a percentage of the emergency shutdown value. For example, if the shutdown value is +30V and the Relative Voltage Threshold is 10%, the OutofRange event occurs if the voltage exceeds +27V.

Generic Interface/Port Performance Settings

These threshold categories configure the monitoring of a adapter's performance characteristics. The categories include basic parameters—such as utilization, errors, broadcast, and packet drops—common to all media types.

Broadcast Threshold

The upper broadcast traffic, expressed as a percentage of the total bandwidth.

Collision Threshold

The upper threshold for collisions, expressed as a percentage of the total number of output packets. This threshold applies only to Ethernet settings for ports, trunks, and interfaces.

Discard Threshold

The upper dropped packets, expressed as a percentage of the total number of packets.

Error Threshold

The upper packet errors, expressed as a percentage of the total number of packets. Operations Manager generates the HighErrorRate event when both Error Threshold and Error Traffic Threshold are reached or exceeded.

Error Traffic Threshold

The upper packet rate, expressed as a percentage of the total bandwidth. Operations Manager generates the HighErrorRate event when both Error Threshold and Error Traffic Threshold are reached or exceeded. The value for Error Traffic Threshold can include up to two decimal places.

Queue Drop Threshold

The acceptable percentage of packets dropped because of full queues, expressed as a percentage of the total number of packets.

Utilization Threshold

The upper link utilization, expressed as a percentage of the total bandwidth.

Interface/Port Flapping Settings

These settings control the analysis of network adapters (ports and interfaces) that are continually going up and down, or flapping. Flapping analysis monitors SNMP link down traps to identify a flapping network adapter. Operations Manager reports flapping as a fault condition. For more information, see Appendix H, "How Operations Manager Calculates Repeated Restarts and Flapping."

---

Note Interface/Port Flapping Settings are disabled by default for some port and interface groups. For more information, see Table 18-11.

---

Link Trap Threshold

The number of SNMP link down traps that must be received within the Link Trap Window for Operations Manager to consider the interface or port flapping. A value of 0 disables flapping analysis.

Link Trap Window

The amount of time used to monitor flapping analysis of a port or interface. If the number of link down traps meets or exceeds the Link Trap Threshold during this window of time, the interface or port is considered to be flapping.

Backup Interface Support Settings

Backup Interface Support Settings configures an interface as a backup. When an interface is identified as a backup:

•The InterfaceOperationallyDown event is not generated if the interface is down.

•The ExceededMaximumUptime event is generated if the interface stays up too long.

---

Note Backup Interface Support Settings are disabled by default for some port and interface groups. For more information, see Table 18-11.

---

The following parameter is included in the Backup Interface Support Settings threshold category.

Maximum Up Time

The maximum length of time, in seconds, that the interface might be up before the ExceededMaximumUptime event is generated. If the value of this parameter is 0, the ExceededMaximumUptime event is disabled.

The minimum value is 0, and the maximum value is 86400.

Dial-On-Demand Interface Support Settings

The Dial-On-Demand Interface Support settings identifies an interface as dial-on-demand. In this case:

•The InterfaceOperationallyDown event is not generated if the interface is down.

•The ExceededMaximumUptime event is generated if the interface stays up too long.

---

Note Dial-on-Demand Interface Settings are disabled by default for some port and interface groups. For more information, see Table 18-11.

---

Maximum Up Time

The maximum length of time that the interface may be up before the ExceededMaximumUptime event is generated. If the value of this parameter is 0, the ExceededMaximumUptime event is disabled.

The minimum value is 0, and the maximum value is 86400.

Processor and Memory Settings (Data Settings)

---

Note For voice-enabled devices, see Processor and Memory Settings (Voice Health).

---

The Processor and Memory Settings control the performance monitoring of a system's processor and its associated memory elements.

Backplane Utilization Threshold

The upper threshold for a switch's backplane utilization, expressed as a percentage of the total backplane bandwidth.

Free Memory Threshold

The lower threshold for the acceptable amount of free memory, as measured by the ratio of free memory to the total memory.

Memory Buffer Miss Threshold

The upper threshold for the number of buffer misses, expressed as a percentage of the total number of buffer requests.

Memory Buffer Utilization Threshold

The upper threshold for the number of buffers used, expressed as a percentage of the total number of buffers.

Memory Fragmentation Threshold

The lower threshold for memory fragmentation. The fragmentation value is the ratio of the largest number of contiguous unallocated bytes to the total amount of free memory. For example, a value of 5 indicates that the largest free buffer must be at least 5% of the free memory.

Processor Utilization Threshold

The upper threshold for processor utilization, expressed as a percentage of the total capacity of the processor.

Reachability Settings

The reachability settings configure reachability parameters for network adapters (ports and interfaces). They also control the analysis of systems that repeatedly restart, triggering Repeated Restarts and Flapping events. The following parameters are included in the Reachability Settings threshold category.

Restart Trap Threshold

The number of SNMP cold or warm start traps that must be received within the amount of time set by the Restart Trap Window parameter for Operations Manager to consider a system to be performing excessive restarts. A value of 0 disables restart analysis. For more information, see Appendix H, "How Operations Manager Calculates Repeated Restarts and Flapping."

---

Note If you want cold and warm start traps to generate events to be displayed immediately in the Alerts and Activities display, set the value of Restart Trap Threshold to 1.

---

Restart Trap Window

The amount of time used to monitor a system's repeated restarts. If the number of start traps meets or exceeds the Restart Trap Threshold during this window of time, the system is considered to be performing excessive restarts.

The minimum value is 30 seconds, and the maximum value is 3600 seconds.

Applying Changes

Changes to polling parameters and threshold values do not take effect until you apply changes, thereby reconfiguring Operations Manager to use the new values. Similarly, after you resume devices or device components that were suspended from polling, you must apply changes for the device elements to be polled.

Before You Begin

Applying changes is a CPU-intensive event that might take between one and five minutes to complete. Therefore, to minimize system impact, consider doing the following when possible:

•Consolidating changes to polling parameters and threshold values, thereby limiting the number of times you will need to apply them.

•Applying changes during a low-usage time.

---

Note Synthetic tests do not run while Operations Manager applies changes.

---

You can apply changes while you are editing polling parameters or thresholds. See:

•Editing Polling Parameters

•Editing Device Group Threshold Settings

•Editing Access Port, Trunk Port, and Interface Group Threshold Settings.

Alternatively, you can apply changes using this procedure.

---

Step 1 Select Administration > Polling and Thresholds > Apply Changes. The Apply Changes page appears.

Step 2 Click Yes to apply the changes:

•If another user has already initiated applying changes, a message is displayed and changes are not applied again.

•If, since the last time changes were applied, polling parameter settings or threshold values have not changed and devices have not been suspended and then resumed, changes will not be applied.

---

---

Tip You cannot directly verify that changes have been applied. However, you can do so indirectly. For example, in response to an event, you change a threshold value and apply changes. After Operations Manager finishes applying changes, you can see whether Operations Manager clears the event.
