"The Oracle RAC Cluster Health Monitor, or CHM, stores operating system metrics in the CHM repository for all the nodes in the cluster. It is a default component of the 11gr2 grid install. It stores information on the key components, including the CPU, memory, process, network, and other OS data in the master repository. This information can be retrieved to troubleshoot and identify any cluster-related issues. The data is also replicated to a standby repository on a different node to prevent it from being lost if the master repository is corrupted."
