INFO Listening on :9100 source="node_exporter.go:111" INFO - boottime source="node_exporter.go:97" INFO Enabled collectors: source="node_exporter.go:90" 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" Once you've downloaded it from the Prometheus downloads page extract it, and run it: # NOTE: Replace the URL with one from the above mentioned "downloads" page. The Prometheus Node Exporter is a single static binary that you can install via tarball. v monitoring/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml \Ĥ.NOTE: While the Prometheus Node Exporter is for *nix systems, there is the Windows exporter for Windows that serves an analogous purpose. # -restart always ensures the container restarts if it goes down due to any circumstances # -v specifies the volume mount and this must point to the location of the prometheus.yml file created in the previous step # -p specifies the port mapping where the left side indicates the host and the right side indicates to container # -name specifies the name of the container Run the Prometheus docker container # -d specifies the container to run in detached state Replace this with the IP of your Pi/Machineģ. # Here a sample IP address has been used (192.168.0.128). # The Port with the node-exporter job will be the port on which node-exporter is deployed (9100 in this case) # The Port with the prometheus job will be the port on which prometheus will be deployed (9090 in this case) Create the Prometheus YAML configuration file as shown # Edit the file using a file editor (nano is this case) Navigate to the Prometheus folder created previously and create a YAML configuration file for Prometheus # Navigate to the prometheus directoryĢ. Verify node exporter is working by browsing to where “IP” is the IP address of the Pi/Machine on which the docker container is deployedĬongratulations!! You’ve successfully deployed Node Exporter on Docker Steps to Deploy Prometheus on Dockerġ. # Node exporter is installed on 9100 port by defaultģ.
