© Prometheus Authors 2014-2023 | Documentation Distributed under CC-BY-4.0 When using Prometheus' file-based service discovery mechanism, the Prometheus instance will listen for changes to the file and automatically update the scrape target list, without requiring an instance restart. Node Exporter will expose these as Prometheus-style metrics. Please help improve it by filing issues or pull requests. Set up and configured Node Exporter to collect Linux system metrics like CPU load and disk I/O. In this guide, you installed and ran a Prometheus Node Exporter and configured Prometheus to discover and scrape metrics from the Node Exporter using file-based service discovery. Go_gc_duration_seconds metric should display two instances with instance labels localhost:9100 and localhost:9200. This is a completely optional step and can be skipped if you do not wish to gather system metrics. The Node Exporter is a project that is maintained through the Prometheus project. To ensure that the Node Exporter is exposing metrics: curl The metrics output should look something like this: # HELP go_gc_duration_seconds A summary of the GC invocation durations. The Node Exporter is an agent that gathers system metrics and exposes them in a format which can be ingested by Prometheus. See this section of the Monitoring Linux host metrics with the Node Exporter guide.
Node exporter prometheus config install#
Install and run a Prometheus instance that is configured to discover the Node Exporter using the targets.json file.Create a targets.json file specifying the host and port information for the Node Exporter.Install and run a Prometheus Node Exporter locally.If you need to use a service discovery system that is not currently supported, your use case may be best served by Prometheus' file-based service discovery mechanism, which enables you to list scrape targets in a JSON file (along with metadata about those targets). Prometheus offers a variety of service discovery options for discovering scrape targets, including Kubernetes, Consul, and many others.
