Clusters

After you register and authenticate an ESP manager node, you can monitor the availability and performance of the cluster to which it belongs using the Monitor Cluster view. This functionality is not available for controller nodes.

Log in with the espMonitorRole role to monitor a cluster. Statistics for the node and cluster are available only if the time-granularity option is enabled on the node in Event Stream Processor project configuration (.ccr) file. See the Event Stream Processor Administrators Guide for more information on the project configuration file.
