Monitoring and Adding Alarm Policies

Note

Alarm policies are stored in compute nodes. Therefore, run the appmgr backup command on each compute node in addition to taking a backup of DCNM.
In case the Monitor>Alarms>Policies window was open while migrating the Performance Manager data, the alarm index may get deleted. In such scenarios, restart the DCNM server for the alarm policies to work as expected.

In Cisco DCNM SAN Federation deployment on Windows and Linux, ensure that the alarm.enable.external value in the Server Properties is set to true on both the Primary and Secondary nodes. Navigate to Administration > DCNM Server > Server Properties. Locate the alarm.enable.external field, and ensure that it is set to true. You must restart DCNM Server to bring this into effect.

You can forward alarms to registered SNMP listeners in DCNM. From Cisco DCNM web UI, choose Administration > DCNM Server > Server Properties, enter an external port address in alarm.trap.listener.address field, click Apply Changes, and restart DCNM services.

Note

Ensure that you select Forwarding check box in Alarm Policy creation dialog window to enable forwarding alarms to external SNMP listener.

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

The Regex definitions are simple expressions but not a complete regex. Variable regions of text are noted using $(LABEL) syntax. Each label represents a regex capture group (.+), which corresponds to one or more characters. The variable texts found in both raise and clear messages are used to associate the two messages. An Identifier is a sequence of one or more labels that appear in both messages. An Identifier is used to match a clear syslog message to the syslog message that raised the alarm. If the text appears only in one of the messages, it can be noted with a label and exclude it from the identifier.

Example: A policy with "Value": "ID1-ID2",

"syslogRaise": "SVC-5-DOWN: $(ID1) module $(ID2) is down $(REASON)"

"syslogClear": "SVC-5-UP: $(ID1) module $(ID2) is up."

In the example, ID1 and ID2 labels can be marked as an identifier to find the alarm. This identifier will be found in corresponding syslog messages. Label “REASON” is in the raise but not in the clear message. This label can be excluded from the identifier, as it has no impact on the syslog message to clear the alarm.

Table 3. 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 4. 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 5. 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.

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.
