Having to tack an incantation onto every simple expression would be annoying; figuring out how to build more complex PromQL queries with multiple metrics is another entirely. They allow us to filter the targets returned by our SD mechanism, as well as manipulate the labels it sets. Enter relabel_configs, a powerful way to change metric labels dynamically. The prometheus_sd_http_failures_total counter metric tracks the number of This block would match the two values we previously extracted, However, this block would not match the previous labels and would abort the execution of this specific relabel step.

And what can they actually be used for? metric_relabel_configs are commonly used to relabel and filter samples before ingestion, and limit the amount of data that gets persisted to storage. stored in Zookeeper. A relabel_configs configuration allows you to keep or drop targets returned by a service discovery mechanism like Kubernetes service discovery or AWS EC2 instance service discovery. We could offer this as an alias, to allow config file transition for Prometheus 3.x. If the new configuration Follow the instructions to create, validate, and apply the configmap for your cluster. Furthermore, only Endpoints that have https-metrics as a defined port name are kept. What if I have many targets in a job, and want a different target_label for each one? I'm working on file-based service discovery from a DB dump that will be able to write these targets out. Default targets are scraped every 30 seconds. their API.

OpenStack SD configurations allow retrieving scrape targets from OpenStack Nova The relabel_config step will use this number to populate the target_label with the result of the MD5(extracted value) % modulus expression. vmagent can accept metrics in various popular data ingestion protocols, apply relabeling to the accepted metrics (for example, change metric names/labels or drop unneeded metrics) and then forward the relabeled metrics to other remote storage systems, which support Prometheus remote_write protocol (including other vmagent instances).
