Hello,
I am trying to represent in a Grafana dahboard the cumulative count of all
Kubernetes pod phases per a list of nodes.
The metrics uses are from the kube-state-metrics project:
https://github.com/kubernetes/kube-state-metrics/blob/v1.9.4/docs/pod-metrics.md
- kube_pod_info
- kube_pod_status_phase
The *kube_pod_status_phase* serie does not have a *node* label, while the
*kube_pod_info* does.
I have tried to join the two series using the group_left function of
Prometheus, but it seems that I can't conditionally select on the joined
label.
My query currently looks like the following:
sum(sum(kube_pod_info{cluster_id="$region",node=~"$node"} * on(pod,
namespace) group_right(node) kube_pod_status_phase{cluster_id="$region"}) by
(node,phase)) by (phase)
I get the following as a result (taken from the Grafana panel legend):
kube_pod_status_phase{phase="Running"} 57
kube_pod_info{} 8
kube_pod_status_phase{phase="Pending"} 0
kube_pod_status_phase{phase="Failed"} 0
kube_pod_status_phase{phase="Unknown"} 0
kube_pod_status_phase{phase="Succeeded"} 0
I would like to count the number of pods (according to the selected nodes)
grouped by pod phase.
What do I need to change to achieve that ?
Thanks
William
