Prometheus - PromQL - filter by dict attribute

Question

I am trying to get memory usage by K8S PODs in particular states only:

sum(container_memory_usage_bytes{kube_pod_status_phase{phase="Pending"}})

but am getting an error: "parse error: unexpected left brace '{'"

What's the correct syntax?

Answer 1

if you want to calculate sum memory usage in kube_pod_status_phase:

sum(container_memory_usage_bytes) by (kube_pod_status_phase)

or if you want to sum all memory usage:

sum(container_memory_usage_bytes)
