Configuration Examples for Alarm Management and Logging
Correlation
This section provides these configuration examples:
Increasing the Severity Level for Alarm Filtering to Display Fewer Events and
Modifying the Alarm Buffer Size and Capacity Threshold: Example
This configuration example shows how to set the capacity threshold to 90 percent, to reduce the size of the
logging events buffer to 10,000 bytes from the default, and to increase the severity level to errors:
!
logging events threshold 90
logging events buffer-size 10000
logging events level errors
!
Increasing the severity level to errors reduces the number of alarms that are displayed in the logging events
buffer, because only alarms with a severity of errors or higher are displayed. Increasing the threshold capacity
to 90 percent reduces the time interval between the threshold crossing and wraparound events; the logging
events buffer thus does not generate a threshold-crossing alarm until it reaches 90 percent capacity. Reducing
the size of the logging events buffer to 10,000 bytes decreases the number of alarms that are displayed in the
logging events buffer and reduces the memory requirements for the component.
Configuring a Nonstateful Correlation Rule to Permanently Suppress Node
Status Messages: Example
This example shows how to configure a nonstateful correlation rule to permanently suppress node status
messages:
logging correlator rule node_status type nonstateful
timeout 4000
rootcause PLATFORM INVMGR NODE_STATE_CHANGE
nonrootcause
!
!
logging correlator apply rule node_status
all-of-router
!
In this example, three similar messages are identified as forwarded to the syslog process simultaneously after
a card boots:
