get CPU Usage in cores

[Darshil Saraiya]

I want to get CPU usage in cores. I searched the metrics that prometheus provides. Here is the list of cpu metrics:

cluster:cpu_allocation:percent

cluster:node_cpu_use:percent

cluster_namespace_controller_pod_container:cpu_usage:rate

cluster_namespace_controller_pod_container:spec_cpu_shares

container_cpu_cfs_periods_total

container_cpu_cfs_throttled_periods_total

container_cpu_cfs_throttled_seconds_total

container_cpu_system_seconds_total

container_cpu_usage_seconds_total

container_cpu_user_seconds_total

container_spec_cpu_period

container_spec_cpu_quota

container_spec_cpu_shares

go_memstats_gc_cpu_fraction

kube_node_status_allocatable_cpu_cores

kube_node_status_capacity_cpu_cores

kube_pod_container_resource_limits_cpu_cores

kube_pod_container_resource_requests_cpu_cores

machine_cpu_cores

node_cpu

process_cpu_seconds_total

I can not get CPU usage in cores.

These two are usage in cores.

You want something like

rate(container_cpu_usage_seconds_total[5m])

The X_seconds_total metrics "count" the time spent executing since the container was created. A container using 53% of a core is executing 530ms out of every second, so the counter increases at 0.53 seconds per second, and the rate function calculates exactly that.

See this page

https://prometheus.io/docs/querying/examples/

for more examples.

I find that  promethues that rate(container_cpu_cfs_throttled_seconds_total[1m]) > 1  ,Theoretically it can’t be > 1? is it  container_cpu_cfs_throttled for all cpu ?
