Nodes

After you register and authenticate an ESP node, you can monitor its availability and performance using the Monitor Node view. Log in using the espMonitorRole role to monitor a node.

Statistics for the node are available only if the time-granularity option is enabled on the node in the Event Stream Processor project configuration (.ccr) file. See the Event Stream Processor Administrators Guide for information on the project configuration file.
