Configuring Logging and Logging Correlation

F I N A L D R A F T — C i s c o C o n f i d e n t i a l

Alarm Logging Correlation

Alarm logging correlation is used to group and filter similar messages to reduce the amount of redundant logs and isolate the root causes of the messages.

For example, the original message describing the online insertion and removal (OIR) and system state being up or down can be reported, and all subsequent messages reiterating the same event can be correlated. When you create correlation rules, a common root event that is generating larger volumes of follow-on error messages can be isolated and sent to the correlation buffer. An operator can extract all correlated messages for display later, should the need arise. See Cisco ASR 9000 Series Aggregation Services Router System Management Configuration Guide for more information.

Configuring Basic Message Logging

Numerous options for logging system messages in Cisco IOS XR software are available. This section provides a basic example.

To configure basic message logging, complete the following steps:

SUMMARY STEPS

1.configure

2.logging {ip-address hostname}

3.logging trap severity

4.logging console [severity]

5.logging buffered [severity buffer-size]

6.commit

7.end

8.show logging

DETAILED STEPS

		Command or Action	Purpose
	Step 1
	Step 1	configure	Enters global configuration mode.
		Example:
		RP/0/RSP0/CPU0:router# configure
	Step 2
	Step 2	logging {ip-address hostname}	Specifies a syslog server host to use for system logging.
		Example:
		RP/0/RSP0/CPU0:router(config)# logging 10.1.1.1
	Step 3
	Step 3	logging trap severity	Limits the logging of messages sent to syslog servers to
			only those messages at the specified level.
		Example:	• See Table 4-2for a summary of the logging severity
		RP/0/RSP0/CPU0:router(config)# logging trap	levels.
		debugging
