There are a few options to filter or allowlist metrics before they are sent to the remote storage via remote_write in Prometheus: 1. Use metric relabeling You can configure relabelling rules on the remote_write config to filter or transform metrics before they are sent. For example: with metrics: my_metric_http{status_code=200, cluster=nim] 100my_metric_http{status_code=500, cluster=nim] 100k8s_metric_memory{container=web, cluster=nim] 100…

Look into Mutation testing. Mutation testing is a type of software testing where certain statements in the source code are changed (or “mutated”) to determine if the test cases can detect the changes. The idea is to ensure that the test suite is robust and can catch defects in the code. Here’s a basic overview…
How to join labels of 2 different metrics on PromQL
Look into the situation Đầu tiên chúng ta có 2 metric labels như sau: Metrics and Labels: Look into kube_pod_container_info metrics. With kube_pod_container_info Look into windows_container_cpu_usage_seconds_kernelmode windows_container_cpu_usage_seconds_kernelmode thì có container_id, nhưng lại không có namespace, pod, container==> Bằng mắt: thì chúng ta không thể nào nhận biết được CPU usage này của container nào. Từ…
