What I used to do in the past was to customize prometheus. relabel component that has a single rule. Prometheus metrics from recording rules. These relabeling rules are applied post-scrape against the metrics returned from the scraped target, no __meta* labels are present. To better explain, I have these couples of hosts (host=instance): host1. Some of the metrics which the Node Exporters exports have a mountpoint label. +" replacement: It just sets an empty value to url_rule label for metrics with names starting from test_ prefix. *"} Basically i want my regex to be compared with all label values . relabel is to filter log entries or We are using Prometheus as the monitoring component in our Kubernetes cluster to observe incoming requests to our pods and assist in autoscaling when requests exceed the predefined threshold. Component health. The value for $1 will come from elsewhere (list of assets). metric_relabel_configs: - source_labels: [__address__] target_label: instance Recording rules allow you to pre-compute frequently needed or computationally expensive expressions and save the results as a new set of time series. yaml |__b1. The stack looks like this: The prometheus UI will be made available under localhost:9090. Prometheus is a powerful, widely used open source monitoring tool. For example, when measuring HTTP latency, we might use labels to record the HTTP method and status returned, which endpoint was called, and which server was responsible for the request.
