![]() So it seems as if EnvironmentFile from the unit keeps precedence over Environment in the drop-in unit. However, if I comment-out EnvironmentFile in the unit file it listens on 127.0.0.1:9101 ( tcp), as I want it to. The drop-in is meant to change this to 9101 and let the service listen only on localhost.Īfter systemctl start prometheus-node-exporter the service listens on :::9100 ( tcp6). the node exporter's default port 9100 applies. etc/default/prometheus-node-exporter sets ARGS="", i.e. It is relative to this unit from Debian package prometheus-node-exporter ( stretch-backports version): # /lib/systemd/system/rviceĭescription=Prometheus exporter for machine metricsĮnvironmentFile=/etc/default/prometheus-node-exporterĮxecStart=/usr/bin/prometheus-node-exporter $ARGS For a list of trademarks of The Linux Foundation, please see our Trademark Usage page.I have a this drop-in unit: # /etc/systemd/system//nfĮnvironment=ARGS=-web.listen-address=localhost:9101 I like hacking through software engineering problems. The Linux Foundation has registered trademarks and uses trademarks. Thats why Prometheus exporters, like the node exporter, exist. © Prometheus Authors 2014-2023 | Documentation Distributed under CC-BY-4.0 Next, check if anything is anything is still listening on port 9100: ss -tapn ( sport :9100 ). zypper rm golang-github-prometheus-nodeexporter. Please help improve it by filing issues or pull requests. Try to terminate any still running node-exporter processes and uninstall its RPM: systemctl disable -now prometheus-nodeexporter. ![]() The average network traffic received, per second, over the last minute (in bytes) In your case, Prometheus is running on docker, which means that the node exporter is located outside of the container. The filesystem space available to non-root users (in bytes) The average amount of CPU time spent in system mode, per second, over the last minute (in seconds) Once the Node Exporter is installed and running, you can verify that metrics are being exported by cURLing the /metrics endpoint: curl You should see output like this: # HELP go_gc_duration_seconds A summary of the GC invocation durations. INFO Listening on :9100 source="node_exporter.go:111" Navigate to localhost:9090/graphin your browser and use the main expression bar at the top of the page to enter expressions. The other targets are working (in the Prometheus UI) and I even got data, but not for node-exporter and kube-state-metrics. Now that Prometheus is scraping metrics from a running Node Exporter instance, you can explore those metrics using the Prometheus UI (aka the expression browser). In the stack, everything get deployed correctly, but somehow, prometheus can't find node-exporter and kube-state-metrics. INFO - boottime source="node_exporter.go:97" Everything works but the kube-prometheus-stack. INFO Enabled collectors: source="node_exporter.go:90" sudo nano /etc/prometheus/prometheus.yml. You should see output like this indicating that the Node Exporter is now running and exposing metrics on port 9100: INFO Starting node_exporter (version=0.16.0, branch=HEAD, revision=d42bd70f4363dced6b77d8fc311ea57b63387e4f) source="node_exporter.go:82" Add the new scrape config for the new node exporter to the Prometheus configuration YML on your Prometheus server. Once you've downloaded it from the Prometheus downloads page extract it, and run it: wget */node_exporter-*.* The Prometheus Node Exporter is a single static binary that you can install via tarball. NOTE: While the Prometheus Node Exporter is for *nix systems, there is the Windows exporter for Windows that serves an analogous purpose.
