oclumon can be used to query the CHM repository to display node-specific metrics for a specified time period.The cluster logger service manages the operating system metric database in the Oracle Grid Infrastructure Management Repository. If the cluster logger service fails (because the service is not able come up after a fixed number of retries or the node where it was running is down), Oracle Clusterware starts ologgerd on a different node. Another ologgerd is spawned for every additional 32 nodes (which can be a sum of Hub and Leaf Nodes). There is one cluster logger service, ologgerd, for every 32 nodes in a cluster. The cluster logger service receives the information from all the nodes and persists in a Oracle Grid Infrastructure Management Repository database. The system monitor service (osysmond) is the monitoring and operating system metric collection service that sends the data to the cluster logger service. There is one system monitor service on every node.
