Configuring an SNMP Alarm on a C Series Controller (SRC CLI)


You can configure SNMP to establish alarms for custom monitors.


Configure only one monitor test at a time.

To configure an SNMP alarm:

  1. Specify an SNMP username.

    See Configuring an SNMPv3 Security Name for SNMP Monitoring (SRC CLI).

  2. From configuration mode, access the configuration statements that configures an alarm. For example:

    where saeHeapUsage is the name of the alarm.

  3. Specify the number of seconds between which SNMP samples the value of an object. For example:

  4. Specify whether to sample the actual value of the object or the difference between two values. For example, to use the actual of the object:

    If you set the sample type to delta-value, you can configure a discontinuity check. See Defining a Discontinuity Check to Validate Delta Values (SRC CLI).

  5. (Optional) Indicate that an alarm not be sent when the alarm is initially activated.

  6. (Optional) Specify the name of the event to be generated in response to an alarm condition. For example:

  7. Specify the name or object identifier (OID) of the MIB variable to be monitored. For example:

  8. (Optional) Specify whether to monitor the SNMP object instance identified by a variable attribute. To monitor the SNMP object instance specified by the variable attribute:

    Do not enable the strict-oid option when you monitor a column of an SNMP MIB table. An alarm for a column monitors the column on all entries of the table. If an entry for an object in the column passes an alarm test, an event is generated for that object.

  9. Configure a Boolean, existence, or threshold test for the alarm.
