Statistics

Indicators

• event ingestion metrics: the number of accepted and discarded events and the event stream rate in events per second
• data rate: the volume of data received per unit of time
• average event size: used with the data rate to estimate network and disk load
• queue load: current ingestion queue usage relative to its capacity
• memory circuit breaker state: current memory usage relative to the limit and whether the circuit breaker has tripped
• number of open correlation windows: the number of rule states currently stored in memory
• CPU and memory usage: processor load and the amount of memory used by the node process
• last event ingestion: the time when the correlator last received an event

Cluster State

The cluster node list shows each node's roles and identifies the current cluster leader. A master node participates in the metadata quorum, while a replica without this role is a non-voting member.
