Infrastructure Integration

The System integration is enabled by default which means the user can see all of the below metrics in Epoch without any additional configuration.

Infrastructure Datasources

Datasource Available Aggregations Unit Description
cpuGuest avg max min sum % The percent of time the CPU spent running the virtual processor. Only applies to hypervisors.
cpuIdle avg max min sum % Percent of time the CPU spent in an idle state.
cpuWait avg max min sum % The percent of time the CPU spent waiting for IO operations to complete.
cpuStolen avg max min sum % The percent of time the virtual CPU spent waiting for the hypervisor to service another virtual CPU. Only applies to virtual machines.
cpSystem avg max min sum % The percent of time the CPU spent running the kernel.
cpuUser avg max min sum % The percent of time the CPU spent running user space processes.
memBuffers avg max min sum byte The amount of physical RAM used for file buffers.
memCached avg max min sum byte The amount of physical RAM used as cache memory.
memPhysFree avg max min sum byte The amount of free RAM.
