Table 5-2 Collector Status and Validation

Collector Status	Description	Tasks
Scheduled	Collector is scheduled for a future date and time.	Allows you to edit or delete the collectors. You cannot start, stop, or monitor the collectors.
Configuring	Configuration of the collector is in progress.	Allows you to edit or delete the collectors. You cannot start, stop, or monitor the collectors.
Running	Collector is configured at the source router and the polling is in progress.	Allows you to stop, monitor, edit, or delete the collectors. You cannot start the collectors.
Stopped	Collectors that are manually stopped and not being polled by IPM.	Allows you to start, delete, or edit the collectors. You cannot stop or monitor the collectors.
Completed	Collector has reached its End Time and polling will not be performed again for this collector by IPM.	Allows you to delete the collectors. You cannot start, stop, edit, or monitor the collectors.
Config Failed	Configuration of the collector failed on the source router. This may be caused by one of the following: •Low memory allocated for IP SLA on the source router. •Source router does not support the operation that you have selected while creating the collector. For example, for ICMP Jitter operation, you must select a source router with IOS version > 12.4.	Allows you to edit or delete the collectors. You cannot start, stop, or monitor the collectors.
Dormant	Collector is inactive on the source device. As a result, IPM does not poll for the statistical data during this period.	Allows you to edit or stop the collectors. You cannot start, delete, or monitor the collectors.
Source Not Responding	Collector will move to this status while configuring/reconfiguring/polling statistics of a collector due to: •Invalid credentials •Device is not reachable	Allows you to edit or delete the collectors. You cannot start, stop, or monitor the collectors.
Collector Transient Status
Updating	Editing a collector is in progress.	Allows you to delete the collectors. You cannot start, stop, or monitor the collectors.
Resuming	Intermediate status between Dormant and Running.
Stopping	Intermediate status between Running and Stopped.
Completing	Intermediate status between Running and Completed.
Dormant Pending	Intermediate status between Running and Dormant.
Deleting	Collector deletion is in progress.
Reconfiguring	Intermediate status between Config Failed and Running. Or When the collector is missing on the source router.

Filtering Collectors

The Filter option available in the IPM Collector Management dialog box, allows you to filter the Collectors based on certain fields and value. The filter operation uses "contains"as the default criteria to filter the Collectors based on the string provided in the filter text area. The Collector filter operation is not case sensitive.

You can filter the Collectors based on any of the following fields:

•All

•Collector Name

•Source

•Target

•Operation

•Status

Example:

If you want to filter the Collectors based on Collector Name and with value chen:

1. From the Filter Drop down, select Collector Name.

2. In the Fiter text area enter chen

3. Click Filter

By default the filter operation uses "contains" to filter the Collectors.

All those Collectors whose names contain the value chen are filtered and provided in the results:

ChenColl

HTTPChenColl

Collector License Information

The number of collectors that you create in IPM depends on the device license limit. For example, if you have a license for 100 devices, you are allowed to create up to 300 collectors in IPM as shown in Table 5-3.

For more information on the device license, see Licensing Behavior While Adding Devices.

Table 5-3 Collector License Information

Device License	Licensed Number of Collectors
100	300 Collectors
300	1000 Collectors
1500	1500 Collectors
5000	2000 Collectors

If the number of collectors you add exceeds the licensed number of collectors, you can add either 10% of the licensed limit or additional 100 collectors, whichever is minimum, apart from the licensed number of collectors.

Examples

1. If you have a license for 100 devices, you can create up to 310 collectors in IPM, as 10% of 300 collectors is 10 collectors.

2. If you have a license for 5000 devices, you are allowed to create up to 2100 collectors in IPM. You can add additional 100 collectors more, apart from the licensed limit (2000 collectors). This is because 10% of 2000 collectors is 200 collectors, which is more than 100 collectors.

Working with IPM Collectors

A collector is defined as an entity that encompasses a source router, a target device, an operation, and the collector schedule. IPM allows you to create one or more collectors by selecting one source device, multiple target devices and operations.

The number of collectors you create depends on the device license. For more information on the device license, see Table 5-3.

After you create the collectors, they are configured on the source router by IPM to collect the network performance statistics.

Creating collectors involve:

•Specifying Source Devices

•Specifying Target Devices

•Specifying IPM Operations

•Defining Collectors

This section also contains information on:

•Viewing the Collector List

•Viewing the Collector Details

•Editing a Collector

•Deleting Collectors

•Viewing Collector Graphs

•Exporting Collector Configuration Information

•Importing Collector Configuration Information

•Monitoring a Collector

•Stopping the Collectors

•Starting the Collectors

Specifying Source Devices

IPM source is a device from which you initiate operations for measuring network performance statistics. Each source must be IP SLA capable and an SNMP agent.

The following MIBs are used by IPM to retrieve required information:

•RttMonMIB

•SystemMIB

The source devices are listed under Source Device Selector on the Collector Configuration page.

This list contains only IP SLA capable devices under the respective MDF categories and also in "All Devices" folder.

For more information on selecting devices, see Adding Devices Using Device Management.

Specifying Target Devices

IPM targets are destination devices for which you want to gather network performance statistics. A target can be any IP-addressable device or a Cisco device running the IP SLA Responder on which the source router performs IP SLA operations. Target devices with IP SLA Responder capability provide more accurate measurements than the other target devices.

---

Note The IP SLA Responder is supported only in Cisco IOS 12.1(2)T or later. We strongly recommend that you use software release 12.1 or later.

---

For more information on selecting devices, see Adding Devices Using Device Management.

Specifying IPM Operations

IP SLA operations are used to create collectors that is configured on the source router to measure network performance statistics.

IPM supports the following IP SLA operations:

•Echo Operations

–Echo

–Path Echo

–UDP Echo

•Jitter Operations

–ICMP Jitter

–UDP Jitter

•Services Operations

–DNS

–DHCP

–HTTP

–FTP

–DLSw

–TCP Connect

•VoIP-related Operations

–Gatekeeper Registration Delay

–Call Setup Post Dial Delay

–RTP

For more information, see Managing IPM Operations.

Defining Collectors

IPM provides a single wizard-based approach that leads you through the procedure to create multiple collectors. This wizard process involves the following four steps:

•Configuring Collectors

•Selecting Collectors

•Scheduling Collectors

•Viewing the Collector Summary

You must complete all the four tasks in this sequence to create collectors. If you exit the wizard at any stage using Cancel, the details you have specified will be lost and the collectors will not be created.

Configuring Collectors

The Collector Configuration page allows you to configure collectors. You can configure collectors by specifying the collector information, a source device, target devices, and operations.

The collectors are created based on the number of target devices and operations you have selected. If you have selected M target devices and N operations, then M*N collectors are created.

You need not specify a target device for operations such as VoIP Gatekeeper Registration Delay and VoIP Post Dial Delay.

---

Note If you select a target device for VoIP Gatekeeper Registration Delay and VoIP Post Dial Delay operations, a message appears indicating that they do not support target device.

---

The number of collectors you create in IPM depends on your device license. For more information on the license, see Collector License Information.

However, we recommend that you create collectors based on the polling interval for better performance of the IPM server. For more information on the mapping between the collector count against the polling interval, see Table 5-8.

To configure collectors:

---

Step 1 Go to LMS Portal and select Internetwork Performance Monitor > Collector Management > Collectors.

The Collector Management page appears.

Step 2 Click Create.

The Collector Configuration page appears.

Step 3 Specify the following details in the Collector Info section:

•The collector name in the Collector Name field.

•A brief description of the collector in the Description field.

Though the Collector Name field allows you to enter more than 15 characters, the source device and trap PDUs display only the first 15 characters for IOS version that is less than 12.4. The IPM database however, contains the complete collector name you have entered.

Step 4 Select the source router from the Source Devices list.

For more information on selecting the source device, see Table 5-4.

Target	Enter the complete or part of the Target name.
Operation	Enter the complete or part of the Operation name.

---

Scheduling Collectors

The Schedule page allows you to specify the collector type, schedule the start and end time details for the collectors to configure, and specify the polling time intervals.

To schedule collectors:

---

Step 1 Select one of the following from the Collector Type section:

•Historical/Statistical—Gathers data and stores it in the IPM database for future analysis. This is the default setting.

•Monitored/Real-time—Allows you to monitor network performance in real-time, but the network performance data is not stored in the IPM database.

If you have selected Monitored/Real-time as the type, then Start Time Details, End Time Details, and Poller Settings fields would be disabled.

Step 2 Define a schedule for the selected collectors in the Start Time Details section:

•Immediate—Starts the collector immediately after it is configured. This is the default setting.

•Date—Select from the Calendar icon. The collector will start at the specified date. The default setting for Date is the current date. That is, the date on which you define the collector.

The start time of the collector depends on the time defined in the Poller Settings field.

If the date selected is in the future, then the status of the collector in the Collector Management page is Scheduled. At the scheduled start time, IPM configures the collector in the router and the status is reflected in the Collector Management page.

The Date field is disabled if you have selected Immediate as the start time.

Step 3 Specify the end date for the collector in the End Time Details section:

•Forever—Runs the collector continuously. This is the default setting. You can stop the running collector by selecting Internetwork Performance Monitor > Collector Management > Collectors > Stop.

•Duration—Removes the collector from the source router after the specified length of time has expired. The duration is specified in days. You can also specify `0 days' as duration, which represents the current date. For example, if you specify 0 days with polling time intervals 20:00:00 to 23:30:00, the collector stops polling at 23:30:00 hours.

•Date—Select from the Calendar icon. The collector will stop at the specified date. The default setting for Date is the current date. That is, the date on which you define the collector.

The end time of the collector depends on the time defined in the Poller Settings field.

The Duration and Date fields are disabled if you select Forever as the end time.

Step 4 Specify the following in the Poller Settings section:

•Polling Interval—Specifies the polling frequency from IPM server to the source router to collect statistics. Select the polling interval from the drop-down list. The default polling interval is 60 minutes. The polling intervals available are 1, 5, 15, and 30, and 60.

We recommend that you create collectors based on the polling interval for better performance of the IPM server. For more information on this, see Table 5-8.

–You can generate Minute reports and graphs only if you have set the Polling Interval as 1, 5, 15, and 30.

–You can generate Historical reports and graphs for all Polling Interval such as 1, 5, 15, 30, and 60.

Table 5-8 Polling Intervals

Polling Intervals	Number of collectors you can create
1 Minute	60 Collectors
5 Minute	100 Collectors
15 Minute	300 Collectors
30 Minute	500 Collectors
1 Hour (60 Minutes)	2000 Collectors

•Days of Week—Select the days of the week when you want the polling to happen.

•Time—Specify the From and To time interval for the polling to begin. You must specify the time in the format Hour:Minutes:Seconds. The default From and To time are 00:00:00 and 23:59:59 respectively.

Step 5 Click Next.

The CSV file should have the following fields:

Name of the Field	Description	Example
Collector Name	Specify the name of the collector.	echo_coll1_10.77.209.209_echo
Description	Specify a brief description about the collector. This column is optional.
Source Display Name	Specify the display name of the source device	10.77.209.3
Target Display Name	Specify the display name of the target device. The value of this column should be blank for the following operations: •DHCP, •GatekeeperRegistrationDelay, •CallSetupPostDialDelay •EthernetPingAutoIPSLA •EthernetJitterAutoIPSLA If the Operation Type is Ethernet Jitter or Ethernet Ping, the value of this column will be MEPID.	10.77.209.209
Operation Name	You can specify either the system defined or user-defined operations. The name is case-sensitive.	Echo
Operation Type	Specify the numeric value associated with the Operation Types. They are: •Echo Operations –Echo = 1 –Path Echo = 2 –UDP Echo = 5 •Jitter Operations –UDP Jitter = 9 –ICMP Jitter = 16 •Services Operations –DNS = 8 –DHCP=11 –HTTP = 7 –FTP = 12 –DLSw = 10 –TCP Connect = 6 •VoIP Operations –Call Setup Post Dial Delay = 18 –Gatekeeper Registration Delay = 19 –RTP = 14 •Metro Ethernet Operations –Ethernet Ping = 1019 –Ethernet Jitter = 1020 –Ethernet Ping Auto IP SLA = 1119 –Ethernet Jitter Auto IP SLA = 1120	1
Source Interface Address	Specify the source interface address . This column is optional.
Collector Type	Specify the numeric value associated with the type of collector. It can be: •Historical = 1 •Real-time = 2	1
Start Date	Specify the start date in the MM/DD/YYYY format.	08/27/2009
End Date	Specify the end date in the MM/DD/YYYY format.	01/31/2021
Poll Start Time	Specify the poll start time in the Hour:Minutes:Seconds format.	0:00:00
Poll End Time	Specify the poll end time in the Hour:Minutes:Seconds format.	0:00:00
Days Of Week	Specify the days of the week when polling should happen. The numeric value for each day of the week is: •Monday = 1 •Tuesday = 2 •Wednesday = 4 •Thursday = 8 •Friday = 16 •Saturday = 32 •Sunday = 64	If you want the IPM server to poll only on: •Monday,Tuesday and Friday means, it will be: 19 (Mon+Tue+Fri = 1 + 2 + 16 = 19) •Week days, it will be: 31 (Mon+Tue+Wed+Thu+Fri = 1+ 2 + 4 + 8 + 16 = 31) •Saturday and Sunday, it will be: 96 (Sat + Sun = 32 + 64 = 96)
Poll Interval	Specify the frequency with which the IPM server polls the source router to collect the statistics. The value must be in milliseconds.	60000

Monitoring a Collector

You can use the Monitor option to monitor the real-time statistics of a collector in the Running status. The statistical data displayed is not stored in the IPM database.You can view the real-time graph for both Historical/Statistical and Monitored/Real-Time collectors. You can monitor more than one collector's statistics in real time.

The sample interval, in the report, indicates the frequency at which the values are plotted on the real-time graph. For example, if the sample interval is 60 seconds, the values in the graphs are plotted every 60 seconds. The sample interval depends on the operation used by the collector.

To monitor a collector:

---

Step 1 Go to LMS Portal and select Internetwork Performance Monitor > Collector Management > Collectors.

The Collector Management page appears with the list of collectors.

Step 2 Select one of the following collectors for monitoring.

•A collector in Running status if the collector type is Historical/Statistical.

•A collector that has the collector type as Monitor/Real-Time.

Step 3 Click Monitor.

A Real-Time graph appears.

Stopping the Collectors

You can use the Stop option to stop the collectors in Running status. As a result of stopping, the collectors become inactive on the source router and the data polling is stopped.

To stop the collectors:

---

Step 1 Go to LMS Portal and select Internetwork Performance Monitor > Collector Management > Collectors.

The Collector Management page appears with the list of collectors.

Step 2 Select the collectors check box that you want to stop.

The selected collectors must be in the Running status.

Step 3 Click Stop.

The Stop Confirmation dialog box appears.

Step 4 Click OK.

The selected collectors are stopped.

Starting the Collectors

You can use the Start option to start the stopped collectors. As a result of starting, the collector is activated on the source device and IPM starts polling.

To start the collectors:

---

Step 1 Go to LMS Portal and select Internetwork Performance Monitor > Collector Management > Collectors.

The Collector Management page appears with the list of collectors.

Step 2 Select the collectors in Stopped status.
