To include rules in Prometheus, create a file containing the necessary rule statements and have Prometheus load the file via the rule_files field in the Prometheus configuration. Prometheus alerting rule not detecting first time metric increase. Prometheus relabel_configs - multiple target labels. Configuring rules. For example, the following VictoriaMetrics-specific relabeling rule is equivalent to the rule above, but it looks more clear: I want to reduce the number of metrics that are scraped under Kube-state-metrics. * matches any text. is a user error, . yml I expect you used the command to check the config and not the rules. Relabeling rules: - source_labels: [__address__] source_labels: [__address__] target_label: __param_target - source_labels: [__address__] Prometheus relabeling provides powerful control over your monitoring data by dynamically modifying targets, metrics, and alerts at various stages in the monitoring pipeline. Rules are structured into named groups, with each group having the ability to set the evaluation interval (default is 60s, as specified by the evaluation_interval option in the Prometheus configuration file), and an This page documents proper naming conventions and aggregation for recording rules. For some reason, my Pod in k8s could possibly labeled with syscode or cib_syscode, how can I relabel both of them to cib_syscode? That is to say if pod labeled with one of them, choose its label va This relabeling rule adds {foo="bar"} label to all the incoming metrics. S. If no rules are defined, This will spin up prometheus and the static metrics server. *) target_label: __address__ replacement: [__address__]:${1} EDIT: The following seems to work: The deployment is pretty straight-forward, and so is editing the rules, however I could not find my way when trying to relabel the exporters using static_configs when using Prometheus-operator. yml). Understanding these configurations allows you to Hi, thanks all for the help! @brian-brazil I believe the alerting. Learn about discovery. Hi @ThomasBöhm! Would be happy to see your solution indeed. Are you looking to get away from proprietary instrumentation? Are you interested in open source For example, a relabeling rule may keep or drop an object based on a regular expression match, may modify its labels, or may map a whole set of labels to another set. In this video, I explain the concept of relabeling in Prometheus, a powerful tool for filtering and transforming your flows of labeled objects in the Prometh What is rules in Prometheus? Time series queries can quickly become quite complicated to remember and type using the Expression Browser in the default Prometheus . If you want to drop a label with a particular value from the collected metric, then use the following relabeling rule at metric_relabel_configs section of the needed scrape_config: - source_labels: This is a quick demonstration on how to use prometheus relabel configs, when you have scenarios for when example, you want to use a part of your hostname and assign it to a prometheus label.

I used the relabel rules and in green are marked meaningful relabels. These improvements can simplify some relabeling tasks as this one. Recording rules should be of the general form level:metric:operations. Next, *. Labels are sets of key-value pairs that allow us to characterize and organize what’s actually being measured in a Prometheus metric. GitHub Gist: instantly share code, notes, and snippets. In Flow, targets are defined as sets of key-value pairs called labels. The first two will be covered in this lab in detail, so let's dig into their configuration layouts. (In fact, relabel_configs doesn't even have a paragraph. See this article for details. 1. 2.

It connects to the local_system component as its source or target. Prometheus metrics from recording rules. The relabel_configs option in Prometheus allows you to manipulate labels before they are stored. scrape component named scrape_metrics which does the following:.
