PromQL查询以在警报中显示广告连播标签

问题描述

我在Prometheus运算符中具有以下默认警报规则，

   - alert: KubePodNotReady
      annotations:
        message: Pod {{`{{`}} $labels.namespace {{`}}`}}/{{`{{`}} $labels.pod {{`}}`}} has been in a non-ready state for longer than 15 minutes.
        runbook_url: https://github.com/kubernetes-monitoring/kubernetes-mixin/tree/master/runbook.md#alert-name-kubepodnotready
      expr: |-
        sum by (namespace,pod) (
          max by(namespace,pod) (
            kube_pod_status_phase{job="kube-state-metrics",namespace=~".*",phase=~"Pending|UnkNown"}
          ) * on(namespace,pod) group_left(owner_kind) topk by(namespace,pod) (
            1,max by(namespace,pod,owner_kind) (kube_pod_owner{owner_kind!="Job"})
          )
        ) > 0 
      for: 15m
      labels:
        severity: warning

我希望警报显示豆荚的标签“ teamname”。

我可以使用以下表达式获得豆荚标签，

kube_pod_info * on(namespace,pod) group_left kube_pod_labels{label_teamname="example"} 

kube_pod_info * on(namespace,pod) group_left(label_teamname) kube_pod_labels

但是我不确定如何更新警报规则以显示标签。我只是尝试添加标签而不编辑表达式，

  labels:
    severity: warning
    teamname: '{{ $labels.label_teamname }}'

但这没用。

是否需要更改表达式才能在警报中包含团队名称？如果是，请提出如何更改以下表达式。

  expr: |-
    sum by (namespace,pod) (
      max by(namespace,pod) (
        kube_pod_status_phase{job="kube-state-metrics",phase=~"Pending|UnkNown"}
      ) * on(namespace,pod) (
        1,owner_kind) (kube_pod_owner{owner_kind!="Job"})
      )
    ) > 0 

 

解决方法

此表达式对我有用，

(sum by (namespace,pod) (
          max by(namespace,pod) (
            kube_pod_status_phase{job="kube-state-metrics",namespace=~".*",phase=~"Pending|Unknown"}
          ) * on(namespace,pod)   group_left(owner_kind) topk by(namespace,pod) (
            1,max by(namespace,pod,owner_kind) (kube_pod_owner{owner_kind!="Job"})
          )
        ) > 0) * on(namespace,pod) group_left(label_teamname) kube_pod_labels
