Cluster Latency Alarm

The Cluster Latency alarm is raised when cluster latency from all causes (interconnect, GES, LMS overhead) exceeds a specified threshold. Possible causes for this alarm are:

• High interconnect latency caused by overloading of the cluster interconnect.
• Queuing or overloading of GES (Global Enqueue Services) processes or LMS global cache service processes.
• A large amount of cache fusion activity.

Possible solutions to this problem include:

• Increasing the bandwidth of the cluster interconnect.
• Configuring additional GES or LMS processes.
