Epoch datasources provide the cpu, memory, queue status, etc. for monitoring health and performance of Epoch AOC and Epoch Collectors. The datasources also have attributes such as node_uuid and source to identify the stream processors within AOC and collectors.

Datasource Available Aggregations Unit Description
epoch.cpu_stats avg min max percent Percentage of CPU used.
epoch.mem_stats avg min max percent Percentage of Memory used.
