【问题描述】:
利用 prometheus federation 进行 Kubernetes 监控。
尝试为多个集群更改此 promql 查询:
计数
by(node) (sum by(node, cpu) (node_cpu_seconds_total{job="node-exporter"}
* on(namespace, pod) group_left(node) node_namespace_pod:kube_pod_info:))
For multiple clusters, the query is giving:
Error executing query: found duplicate series for the match group {namespace="monitoring", pod="prometheus-k8s-1"} on the right hand-side of the operation: [{__name__="node_namespace_pod:kube_pod_info:", clustername="xyz", environment="dev", job="prometheus", location="haha", namespace="monitoring", node="228d5f45-27cc-4a59-b99d-3bab9ebe3b52", pod="prometheus-k8s-1", prometheus="monitoring/k8s", prometheus_replica="prometheus-k8s-0"}, {__name__="node_namespace_pod:kube_pod_info:", clustername="abc", environment="dev", job="prometheus", location="haha", namespace="monitoring", node="3faf3dfa-f8ab-4b3f-bda7-6662c1aa2a34", pod="prometheus-k8s-1", prometheus="monitoring/k8s", prometheus_replica="prometheus-k8s-1"}];many-to-many matching not allowed: matching labels must be unique on one side
添加 clustername 作为 prometheus 服务器的外部标签..
你能指导我吗?
