Use Cluster Health Monitor to collect diagnostic data to analyze performance degradation or failures of critical operating system resources.
You can now configure Oracle Cluster Health Monitor to operate in local mode to report
the operating system metrics using the
oclumon dumpnodeview command
even if you have not deployed GIMR.
In local mode, you can get only the local node data. The local mode has limited Oracle
Cluster Health Monitor functionality in the deployments where you have not installed
GIMR. In earlier releases, Oracle Cluster Health Monitor required GIMR to report the
operating system metrics using the
oclumon dumpnodeview command.
