通过$labels.<labelname>变量可以访问当前告警实例中指定标签的值。$value则可以获取当前PromQL表达式计算的样本值。 #To insert a firing element's label values:{{ $labels.<labelname>}}#To insert the numeric expression value of the firing element:{{ $value }} 例如,可以通过模板化优化summary以及descrip...
同时Alertmanager的UI也会根据这两个标签值,显示告警信息。为了让告警信息具有更好的可读性,Prometheus支持模板化label和annotations的中标签的值。 通过$labels.<labelname>变量可以访问当前告警实例中指定标签的值。$value则可以获取当前PromQL表达式计算的样本值。 # To insert a firing element's label values: {{ ...

在K8S 1.16版本,Cadvisor 的指标去掉了 pod_Name 和 container_name 的 label,替换为了pod 和 container。如果你之前用这两个 label 做查询或者 Grafana 绘图,需要更改下 Sql 了。因为我们一直支持多个 K8S 版本,就通过 relabel配置继续保留了原来的**_name。
<labelname>:与正则表达式匹配的字符串[a-zA-Z _][a-zA-Z0-9 _]* <labelvalue>:一串unicode字符 <filepath>:当前工作目录中的有效路径 <boolean>:一个可以取值为true或false的布尔值 <string>:常规字符串 <secret>:一个秘密的常规字符串,例如密码 ...
