Hello!
I'm doing some grafana+prometheus dashboarding for
flink-kubernetes-operator. Reading metrics docs
<https://stackoverflow.com/a/61795256>, I see that I have nice per k8s
namespace lifecycle current count gauge metrics in Prometheus.
Using kubectl, I can see that I have one FlinkDeployment in my namespace:
# kubectl -n stream-enrichment-poc get flinkdeployments
NAME JOB STATUS LIFECYCLE STATE
flink-app-main RUNNING STABLE
But, prometheus is reporting that I have 2 FlinkDeployments in the STABLE
state.
# curl -s <pod_ip>:<prom_port> | grep
flink_k8soperator_namespace_Lifecycle_State_STABLE_Count
flink_k8soperator_namespace_Lifecycle_State_STABLE_Count{resourcetype="FlinkDeployment",resourcens="stream_enrichment_poc",name="flink_kubernetes_operator",host="flink_kubernetes_operator_86b888d6b6_gbrt4",namespace="flink_operator",}
2.0
I'm not sure why I see 2.0 reported.
flink_k8soperator_namespace_JmDeploymentStatus_READY_Count reports only one
FlinkDeployment.
# curl <pod_ip>:<prom_port>/metrics | grep
flink_k8soperator_namespace_JmDeploymentStatus_READY_Count
flink_k8soperator_namespace_JmDeploymentStatus_READY_Count{resourcetype="FlinkDeployment",resourcens="stream_enrichment_poc",name="flink_kubernetes_operator",host="flink_kubernetes_operator_86b888d6b6_gbrt4",namespace="flink_operator",}
1.0
Is it possible that flink_k8soperator_namespace_Lifecycle_State_STABLE_Count
is being reported as an incrementing counter instead of a guage?
Thanks
