Syslog Alarm

Syslog Alarm Policy defines a pair of Syslog messages formats; one which raises the alarm, and one which clears the alarm.

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.

  • Forwarding: You can forward alarms to registered SNMP listeners in Cisco Nexus Dashboard Fabric Controller . From Web UI, choose Settings > Server Settings > Events.


    Note

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

  • Email: You can forward alarm event emails to recipient when alarm is created, cleared or severity changed. From Cisco Nexus Dashboard Fabric Controller Web UI, choose Settings > Server Settings > Events. Configure the SMTP parameters, click Save, and restart Cisco Nexus Dashboard Fabric Controller services.

  • 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 1. 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 2. 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 3. 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
Hardware Health Policy

The hardware health policy is used to raise hardware-related alarms for different parameters, such as fan status, power supply, modular status and all interface-related alarms.

By default, there is a hardware policy called as discovery that is standard with the NDFC installation. This hardware policy defines various conditions for different parameters. You can also create custom hardware policies for the parameters listed above and define regex expressions based on which alarms are raised.

By default, the All Devices option is selected automatically.

  • Policy Name: Specify a name for the policy. It must be unique.

  • Description: Specify a brief description for the policy.

  • Forwarding: You can forward alarms to registered SNMP listeners in Cisco Nexus Dashboard Fabric Controller . From the Web UI, choose Settings > Server Settings > Events.


    Note

    Ensure that you select Forwarding check box while configuring alarm policies to forward alarms to an external SNMP listener.

  • Email: You can forward alarm event emails to recipients when an alarm is created, cleared or when the severity is changed. From Cisco Nexus Dashboard Fabric Controller Web UI, choose Settings > Server Settings > Events. Configure the SMTP parameters, click Save, and restart Cisco Nexus Dashboard Fabric Controller services.

Hardware alarms are raised based on regex expressions that you enter when you are creating the policy.

In the Alarms area, create a hardware health policy to raise alarms for the following parameters:

  • Fan: Define the severity for fan-related alarms and determine the condition for the alarms.

    1. Click the toggle switch next to Fan to enable the fan-related alarms.

    2. Select the severity of the alarm:

      • Critical

      • Major

      • Minor

      • Warning

      • Cleared

    3. Click Edit Regex, then enter the value that will trigger the alarm when the status is not that value.

      For example, if you enter ok in the Trigger alarm when status is not field, NDFC will raise an alarm for any status other than ok, such as N/A.

    4. Click Save.

  • Power Supply: Define the severity for power supply-related alarms and determine the condition for the alarms.

    1. Click the toggle switch next to Power Supply to enable the power supply-related alarms.

    2. Select the severity of the alarm:

      • Critical

      • Major

      • Minor

      • Warning

      • Cleared

    3. Click Edit Regex, then enter the value that will trigger the alarm when the status is not that value.

      For example, if you enter ok in the Trigger alarm when status is not field, NDFC will raise an alarm for any status other than ok, such as failed, OffEnvpower, OffDenied, and so on.

    4. Click Save.

  • Module: Define the severity for module-related alarms and determine the condition for the alarms.

    1. Click the toggle switch next to Module to enable the module-related alarms.

    2. Select the severity of the alarm:

      • Critical

      • Major

      • Minor

      • Warning

      • Cleared

    3. Click Edit Regex, then enter the value that will trigger the alarm when the status matches that value.

      For example, if you were to enter the following value in the Trigger alarm when status matches regex field, as shown in the information (i) button:

      ^(?!ok|poweredDown|okButDiagFailed).*$

      NDFC will raise an alarm when modules are in states other than ok, poweredDown, and OkButDiag failed.

    4. Click Save.

  • Interface Status: Define the severity for interface-related alarms and determine the condition for the alarms.

    1. Click the toggle switch next to Interface Status to enable the interface-related alarms.

    2. Click one or more toggle switches next to the appropriate severity to select the severity of the alarm:

      • Critical

      • Major

      • Minor

      • Warning

      • Cleared

    3. Click Edit Regex, then enter the value that will trigger the alarm when the status matches that value. The provided regex expression is matched against the combined field of admin_status:oper_status:status_reason.

      For example, if you were to enter the following value in the Trigger alarm when status matches regex field:

      ^up:down:(?!Link not connected|XCVR not inserted|sfpNotPresent|Channel admin down).*$

      NDFC will raise an alarm when interfaces are in states that match these values.

    4. Click Save.

Endpoint Locator Alarms

Alarms are registered and created under the External alarm category by the Endpoint Locator (EPL).

Alarm Policy

The EPL external alarm category policy is activated when EPL is enabled on a fabric. Alarms are raised for issues such as Duplicate IP addresses, Duplicate MAC addresses, Endpoints appearing on a VRF and Endpoints disappearing from a VRF, Endpoints moving within a fabric, loss of Route Reflector connectivity, and restoration of Route Reflector connectivity. Depending on the issue, the severity level of the alarm policy can be CRITICAL or MINOR.

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

  • Route Reflector disconnection

  • Detection of a duplicate IP address

  • Detection of a duplicate MAC address

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

  • Movement of an endpoint

  • Appearance of a new VRF in a fabric

  • Number of endpoints in a fabric goes down to 0

  • Number of endpoints in a VRF goes down to 0

  • Disappearance of all endpoints from a switch

  • Connection of a Route Reflector (RR)

CRITICAL alarms are cleared automatically when the condition is corrected. For example, when the connectivity between NDFC and RR is lost, a CRITICAL alarm is generated. This alarm is automatically cleared when the connectivity between NDFC and RR is restored. Other MINOR alarms are automatically cleared after 30 minutes have passed since the alarm was generated.


Note

You must clear the duplicate MAC and duplicate IP alarms after the condition is resolved.

Choose Event Analytics > Alarms > Alarm Policies to display the EPL alarm policies. These alarm policies are not editable on the web UI. Choose Actions > Activate or Deactivate to activate or deactivate the selected policy.

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

  5. Click Add Rule.

Step 5

Perform the following steps to create rules for suppressing events:

Nexus Dashboard Fabric Controller allows you to suppress specified events based on user-specified rules. Such events will not be displayed on the Nexus Dashboard Fabric Controller Web UI and SAN Client. The events will neither be added to the Nexus Dashboard Fabric Controller database, nor forwarded via email or as SNMP traps.

You can view, add, modify, and delete rules from the table. You can create a rule from the existing events. Select an existing event as the template and open the Add Rule window by navigating to Operations > Event Analytics > Events page, select the event and choose Actions > Add Suppresor. The details are automatically ported from the selected event in the events table to the fields of the Add Rule window.

  1. In the Name field, enter a name for the rule.

  2. In the Scope field, select one of the following options - SAN, Port Groups or Any.

    In the Scope field, the LAN/SAN groups and the port groups are listed separately. For SAN and LAN, select the scope of the event at the fabric or group or switch level. You can only select groups for port group scope. If use select Any as the scope, the suppression rule is applied globally.

  3. In the Facility field, enter the name or choose from the SAN/LAN switch event facility list.

    If you do not specify a facility, a wildcard is applied.

  4. In the Type field, enter the event type.

    If you do not specify the event type, wildcard is applied.

  5. In the Description Matching field, specify a matching string or regular expression.

    The rule matching engine uses regular expression that is supported by Java Pattern class to find a match against an event description text.

  6. Check the Active Between check box and select a valid time range during which the event is suppressed.

    By default, the time range is not enabled.

    Note

     

    In general, you must not suppress accounting events. Suppression rule for Accounting events can be created only for certain situations where accounting events are generated by actions of Nexus Dashboard Fabric Controller or switch software. For example, 'sync-snmp-password' AAA syslog events are automatically generated during the password synchronization between Nexus Dashboard Fabric Controller and managed switches. To suppress accounting events, navigate to Operations > Event Analytics > Events page, select the event and choose Actions > Add Suppressor.

  7. Click Add Rule.
