Serial No. column displays the serial number of the switch.
Release column displays the switch version.
License column displays the DCNM license that is installed on the switch.
Up Time column displays the time period for which the switch is active.

Step 3

Click Health to access the Health score window for a device. The Health score window includes health score calculation and health trend. The Overview tab displays the overall health score. All the modules, switch ports and alarms are taken into consideration while calculating the health score. Hover over the graph under Health Trend for detailed information on specific dates. Hover over the info icon next to Alarms to display the number of Critical, Major, Minor, and Warning alarms that have been generated.

Click the Modules tab to display information about the various modules in the device. This tab displays information such as Name, Model name, Serial number, Status, Type, Slot, Hardware revision and Software revision.

Click the Switch Ports tab to display information about the device ports. This tab displays information such as Name, Description, Status, Speed, and the device to which a port is connected .

Click the Alarms tab to display information about the alarms that have been generated. This tab displays information such as alarm Severity, Message, Category, and the Policy that has been activated due to which the alarm is generated.

In the Health column, the switch health is calculated by the capacity manager based on the following parameters:

Total number of modules
Total number of modules impacted by the warning
Total number of switch ports
Total number of switch ports impacted by the warning
Total number of critical severity alarms
Total number of warning severity alarms
Total number of major severity alarms
Total number of minor severity alarms

Step 4

The value in the Health column is calculated based on the following:

Percentage of modules impacted by warnings (Contributes 20% of the total health).
Percentage of ports impacted by warnings (Contributes 20% of the total health).
Percentage of alarms (Contributes 60% of the total health). The critical alarms contribute the highest value to this percentage followed by major alarms, minor alarms and warning alarms.

You may also have your own health calculation formula by implementing the common interface class: com.cisco.dcbu.sm.common.rif.HealthCalculatorRif.

The default Java class is defined as: health.calculator=com.cisco.dcbu.sm.common.util.HealthCalculatorAlarms.

Capacity Manager calculates health only for the license switches. If the health column does not display a value, the switch either does not have a license or it has missed the capacity manager daily cycle.
If the switch is unlicensed, click Unlicensed in the DCNM License column. The Administration > License window appears which allows you to assign a license to the user.
The capacity manager runs two hours after the DCNM server starts. So, if you discover a device after two hours of the DCNM start time, the health will be calculated 24 hours after this DCNM start time

Starting from Cisco DCNM 11.3(1) Release, you can view information about switch health along with the switch summary by clicking on a switch in the Topology window or by choosing Control>Fabrics>Fabric Builder, selecting a fabric and clicking on a switch in the Fabric Builder window.

Note

Set the pmchart.doInterpolate property in the Server Properties window to false to use the Do not interpolate data option.

To export the data into a spreadsheet, choose Export from the drop-down list in the Chart menu and then click Save.

For the Rx/Tx calculation, see the following Rx/Tx calculation.

Note

The conversion for Fabrics is 10 bit = 1 byte and for LAN traffic, the conversion is 8 bit = 1 byte.

Average Rx/Tx % = Average Rx/Tx divided by Speed * 100
Peak Rx/Tx % = Peak Rx/Tx divided by Speed * 100

Note

If the performance tables do not contain any data, see the Performance Setup Thresholds section to turn on performance.

Monitoring a vPC

The virtual port channel (vPC) feature enables you to view the links that are physically connected to different devices as a single port channel. A vPC is an extended form of a port channel which allows you to create redundancy and increase bisectional bandwidth by enabling multiple parallel paths between nodes and allowing load balancing traffic. Traffic is distributed among two single device vPC endpoints. If there is an inconsistency in the vPC configurations, the vPC does not function correctly.

Note

To view the vPC in vPC Performance, both primary and secondary device should be designated to the user. If either one kind of switch is not designated, vPC information is isplayed.

Cisco DCNM Web Client > Monitor> vPC displays only consistent vPCs displays both the consistent and inconsistent vPCs.

You can identify the inconsistent vPCs and resolve the inconsistencies in each vPC by using the Cisco DCNM Web UI > Configure > Deploy > vPC Peer and Web Client > Configure > Deploy > vPC.

Table 1 displays the following vPC configuration details in the data grid view.

You can add alarm policies for the following:

Device Health: Device health policies enable you to create alarms when Device ICMP Unreachable, Device SNMP Unreachable, or Device SSH Unreachable. Also, these policies enable you to monitor chassis temperature, CPU, and memory usage.
Interface Health: Interface health policies enable you to monitor Up or Down, Packet Discard, Error, Bandwidth details of the interfaces. By default all interfaces are selected for monitoring.
Syslog Alarm: Syslog Alarm Policy defines a pair of Syslog messages formats; one which raises the alarm, and one which clears the alarm.

Procedure

Step 1

Choose Monitor > Alarms > Alarm Policies.

Step 2

Select the Enable Alarms check box to enable alarm policies.

Step 3

From the Add drop-down list, choose any of the following:

Device Health Policy: Select the devices for which you want to create policies. Specify the policy name, description, CPU Utilization parameters, Memory Utilization parameters, Environment Temperature parameters, device availability, and device features. Under Device Features, you can select the BFD, BGP, and HSRP protocols. When these check boxes are selected, alarms are triggered for the following traps: BFD- ciscoBfdSessDown, ciscoBfdSessUp, BGP- bgpEstablishedNotification, bgpBackwardTransNotification, cbgpPeer2BackwardTransition (), cbgpPeer2EstablishedNotification, and HSRP- cHsrpStateChange. Please refer https://snmp.cloudapps.cisco.com/Support/SNMP/do/BrowseOID.do?local=en for detailed trap OID definition.
Interface Health Policy: Select the devices for which you want to create policies. Specify the policy name, description, link-state, Bandwidth (In/Out), Inbound errors, Outbound errors, Inbound Discards, and Outbound Discards.

Syslog Alarm Policy: Select the devices for which you want to create policies and then specify the following parameters.

Devices: Define the scope of this policy. Select individual devices or all devices to apply this policy.
Policy Name: Specify the name for this policy. It must be unique.
Description: Specify a brief description for this policy.
Severity: Define the severity level for this syslog alarm policy. Choices are: Critical, Major, Minor, and Warning.
Identifier: Specify the identifier portions of the raise & clear messages.
Raise Regex: Define the format of a syslog raise message. The syntax is as follows: Facility-Severity-Type: Message
Clear Regex: Define the format of a syslog clear message. The syntax is as follows: Facility-Severity-Type: Message

Table 12. Example 1
Identifier	ID1-ID2
Raise Regex	ETHPORT-5-IF_ADMIN_UP: Interface Ethernet15/1 is admin up .
Clear Regex	ETHPORT-5-IF_DOWN_NONE: Interface Ethernet15/1 is down (Transceiver Absent)

In the above example, the regex expressions are part of the syslog messages that appear in the terminal monitor.

Table 13. Example 2
Identifier	ID1-ID2
Raise Regex	ETH_PORT_CHANNEL-5-PORT_DOWN: $(ID1): $(ID2) is down
Clear Regex	ETH_PORT_CHANNEL-5-PORT_UP: $(ID1): $(ID2) is up

Table 14. Example 3
Identifier	ID1-ID2
Raise Regex	ETHPORT-5-IF_SFP_WARNING: Interface $(ID1), High Rx Power Warning
Clear Regex	ETHPORT-5-IF_SFP_WARNING: Interface $(ID1), High Rx Power Warning cleared

Step 4

Click OK to add the policy.

Syslog Messages in Terminal Monitor and Console

The following examples show how the syslog messages appear in the terminal monitor and the console. The regex expression is matched with the part of the syslog messages after the % sign.

leaf-9516# terminal monitor
leaf-9516# conf t
leaf-9516(config)# int e15/1-32
leaf-9516(config-if-range)# no shut
2019 Aug 2 04:41:27 leaf-9516 %ETHPORT-5-IF_ADMIN_UP: Interface
Ethernet15/1 is admin up .
2019 Aug 2 04:41:27 leaf-9516 %ETHPORT-5-IF_DOWN_NONE: Interface
Ethernet15/1 is down (Transceiver Absent)
2019 Aug 2 04:41:27 leaf-9516 %ETHPORT-5-IF_ADMIN_UP: Interface
Ethernet15/2 is admin up .
2019 Aug 2 04:41:27 leaf-9516 %ETHPORT-5-IF_DOWN_NONE: Interface
Ethernet15/2 is down (Transceiver Absent)
2019 Aug 2 04:41:28 leaf-9516 %ETHPORT-5-IF_ADMIN_UP: Interface
Ethernet15/3 is admin up .

The syslog messages in the console have a similar format as they would appear in the terminal monitor, except for the additional port information enclosed in the %$ signs. However, the regex expression is matched with the part of the syslog messages after the last % sign.

1. Log into the DCNM server using SSH.
2. Set the alarm.enable.external property to true in the server.properties file.
  
  The filepath is /usr/local/cisco/dcm/fm/config/server.properties.

Configuration Compliance Alarms

Starting from Cisco DCNM Release 11.3(1), the alarm policies and alarms under the External category are created by the applications running on DCNM. These External alarm policies are created by the applications and cannot be created or added via the DCNM Web UI.

Config-Compliance(CC) is a core application running on DCNM. CC registers and creates Alarms under the External Alarm category.

Config-Compliance : Alarm Policy

This External alarm category policy is activated on creation of the fabric and is enabled on all the devices in that fabric. The severity level of the policy is CRITICAL. If any device in the fabric moves from In-Sync to Out-of-Sync and the Enable Alarms checkbox is selected, a critical severity alarm is generated.

Choose Monitor>Alarms>Policies to display the default alarm policies. This alarm policy is not editable on the web UI. Click Activate or Deactivate to activate or deactivate the selected policy.

In case an alarm policy is deactivated using the DCNM Web UI, any alarms created or cleared for that policy will not be displayed in the Monitor>Alarms>View tab. To delete a policy, select the checkbox next to the policy and click Delete. However, we recommend not deleting a policy from the DCNM Web UI. If a policy is deleted, CC regenerates the policy on the next periodic run or when a Re-sync is triggered at the device level or fabric level under that fabric.

Click the arrow icon next to Critical to display detailed information about the alarm.

An Out-of-Sync status indicates that there is a difference between the intent defined for the device on DCNM and the running configuration on the device. An In-Sync status indicates that the intent defined for the device on DCNM matches the running configuration and CC found no differences between the configurations. For more details on computation of diff, refer Configuration Compliance in DCNM.

When a fabric is deleted, the alarm policy along with all the active alarms for the devices in that fabric are deleted.

Config-Compliance : Active Alarms

Consider a scenario in which CC is running on a fabric and a device in that fabric moves to Out-of-Sync status. This leads to the generation of a Critical severity alarm. Choose Monitor->Alarms->View to display the alarms. These alarms are active until the device moves from Out-of-Sync to In-Sync.

To clear active alarms, select the checkbox next to the alarm, click Change Status and select Clear. In case the same device moves to Out-of-Sync status again, the active alarm is re-created.

To delete active alarms, select the checkbox next to the alarm and click Delete. In case the same device moves to Out-of-Sync status again, a new active alarm is created.

Config-Compliance : Cleared Alarms

When the device that is in Out-of-Sync status moves to In-Sync status, the active alarm is cleared. To view the cleared alarms, select Monitor>Alarms>View>Cleared Alarms. The cleared alarms do not contribute to the overall device health score.

To delete a cleared alarm from the list of cleared alarms, choose Monitor>Alarms>View>Cleared Alarms, select the checkbox next to the alarm, and click Delete. This will delete the selected cleared alarms from the list.

Alarms are cleared when a switch moves from Out-of-Sync to In-Sync. Configuration compliance alarms also contribute to the overall Health score of a device.

For more information on Alarms and Policies, refer Alarms.

Health Monitor Alarms

Starting from Cisco DCNM Release 11.4(1), alarms are registered and created under the External alarm category by the Health Monitor.

Health Monitor: Alarm Policy

The Health Monitor external alarm category policy is automatically activated and enabled on all the devices in a fabric. The severity level of this alarm policy can be MINOR, MAJOR, or CRITICAL.

Alarms are raised and categorized as CRITICAL for the following events:

Elasticsearch (ES) Cluster Status is Red: Critical (For Cluster/HA mode only)
CPU/Memory/Disk Utilization/ES JVM Heap Used Percentage >= 90%

Alarms are raised and categorized as MAJOR for the following events:

ES Cluster Status is Yellow (For Cluster/HA mode only)
ES has unassigned shards (For Cluster/HA mode only)
CPU/Memory/Disk Utilization/ES JVM Heap Used Percentage >= 80% and <90%

Alarms are raised and categorized as MINOR for the following events:

CPU/Memory/Disk Utilization/ES JVM Heap Used Percentage >= 65% and <80%
Kafka: Number of partitions without active leader > 0
Kafka: Qualified partition leader not found. Unclear leaders > 0

Choose Monitor>Alarms>Policies to display the Health Monitor alarm policies. These alarm policies are not editable on the web UI. Click Activate or Deactivate to activate or deactivate the selected policy.

In case an alarm policy is deactivated using the GUI, any alarms created or cleared for that policy will not be displayed in the Monitor>Alarms>View tab. To delete a policy, select the checkbox next to the policy and click Delete. However, we recommend not deleting a policy from the GUI. When a fabric is deleted, the alarm policy along with all the active alarms for the devices in that fabric are deleted.

Health Monitor: Active Alarms

Choose Monitor>Alarms>View to display the active alarms.

To clear active alarms, select the checkbox next to the alarm, click Change Status and select Clear.

To delete active alarms, select the checkbox next to the alarm and click Delete.

Health Monitor: Cleared Alarms

To view the cleared alarms, select Monitor>Alarms>View>Cleared Alarms.

Click the arrow icon to display detailed information about the required alarm.

To delete a cleared alarm from the list of cleared alarms, select the checkbox next to the alarm and click Delete.

For more information on Alarms and Policies, refer Alarms.
