Prometheus Trainings by PromLabs | Relabeling The labelkeep action performs the following steps, in sequence:. It matches the regular expression in regex against all label names.; It keeps only those labels that match. The labeldrop action works like labelkeep, but drops a label rather than keeping it.. Use case examples. Let's look at some example use cases for the labelkeep action.. Removing HA replica labels from alerts Reducing Prometheus metrics usage | Grafana Cloud documentation To drop a specific label, select it using source_labels and use a replacement value of "". To bulk drop or keep labels, use the labelkeep and labeldrop actions. You can use a relabel_config to filter through and relabel: Scrape targets Samples and labels to ingest into Prometheus storage Samples and labels to ship to remote storage

Prometheus: Adding a label to a target - Niels's DevOps Musings Prometheus relabel configs are notoriously badly documented, so here's how to do something simple that I couldn't find documented anywhere: How to add a label to all metrics coming from a specific scrape target. Example scrape_configs: # The job name is added as a label `job=` to any timeseries scraped from this config.

Prometheus target labels dropped

How Prometheus Querying Works (and Why You Should Care) If your target exposes ephemeral labels, you can consider dropping them using the drop action in relabel_config in Prometheus scrape_config. 2. Keep your scrape interval high—you can use downsampling for this. The scrape interval is the interval in which Prometheus scrapes a metric target. Prometheus relabeling tricks - Medium action: labeldrop This snippet will drop the label with name container_label_com_amazonaws_ecs_task_arn from all metrics and time-series under the job. This is useful when you don't want Prometheus... Writing exporters | Prometheus The second case is when a label is really a target label. These are things like region, cluster names, and so on, that come from your infrastructure setup rather than the application itself. ... These should all be dropped, as they're not very useful and add clutter. Prometheus can calculate rates itself, and usually more accurately as the ...

Prometheus target labels dropped. Configuration | Prometheus If more than this number of targets are present after target # relabeling, Prometheus will mark the targets as failed without scraping them. # 0 means no limit. This is an experimental feature, this behaviour could # change in the future. [ target_limit: | default = 0 ] Where must be unique across all scrape configurations. Labels in Prometheus alerts: think twice before using them As developers, we hear a lot about the importance of monitoring and alerts. But without proper notification, we might spend too much time trying to understand what really is going on. This blog post will give you an overview of common caveats of using labels in Prometheus alerts and demonstrate some technics how to get concise and easy to understand notifications. Drop data using Prometheus remote write - New Relic This tells Prometheus that you want to do some action against metrics with these labels. To limit which metrics with these labels are affected, you must include some value for regex. By default this value is set to .* and it will include all metrics. In this case, it will drop all metric data points coming out of Prometheus via remote write. Understanding and using the multi-target exporter pattern - Prometheus After saving the config file switch to the terminal with your Prometheus docker container and stop it by pressing ctrl+C and start it again to reload the configuration by using the existing command. The terminal should return the message "Server is ready to receive web requests."

HTTP API | Prometheus The following endpoint returns an overview of the current state of the Prometheus target discovery: GET /api/v1/targets Both the active and dropped targets are part of the response by default. labels represents the label set after relabelling has occurred. Advanced Service Discovery in Prometheus 0.14.0 Global labels, which are assigned to every target scraped by the Prometheus instance. The job label, which is configured as a default value for each scrape configuration. Labels that are set per target group within a scrape configuration. Advanced label manipulation via relabeling. Each stage overwrites any colliding labels from the earlier stages. Prometheus: metric_relabel_configs does not drop __-prefixed labels as ... The docs suggest using the __-prefix (or even __tmp prefix) for such temporary labels and states that such labels will be removed after completing relabeling: Labels starting with __ will be removed from the label set after relabeling is completed. This does not seem to be the case. Writing exporters | Prometheus The second case is when a label is really a target label.
