Configuring Logging and Logging Correlation

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 a card 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 IOS XR System Management
Configuration Guide for more information.
