Start by creating the Systemd service file for Node Exporter. The steps for running Node Exporter are similar to those for running Prometheus itself. Now that you’ve installed Node Exporter, let’s test it out by running it before creating a service file for it so that it starts on boot. Lastly, remove the leftover files from your home directory as they are no longer needed. $ sudo cp node_exporter-0.15.1.linux-amd64/node_exporter /usr/local/bin $ sudo chown node_exporter:node_exporter /usr/local/bin/node_exporter This will create a directory called node_exporter-0.15.1.linux-amd64 containing a binary file named node_exporter, a license, and a notice.Ĭopy the binary to the /usr/local/bin directory and set the user and group ownership to the node_exporter user that you created in Step 1. If the checksums don’t match, remove the downloaded file and repeat the preceding steps.

Verify the downloaded file’s integrity by comparing its checksum with the one on the download page. Use the sha256sum command to generate a checksum of the downloaded file: You can find the latest binaries along with their checksums on Prometheus' download page. Node Exporter provides detailed information about the system, including CPU, disk, and memory usage.įirst, download the current stable version of Node Exporter into your home directory.

To expand Prometheus beyond metrics about itself only, we'll install an additional exporter called Node Exporter. Sudo useradd - no-create-home - shell /bin/false node_exporter Step 2 - Downloading Node Exporter We’ll use these accounts throughout the tutorial to isolate the ownership on Prometheus’ core files and directories.Ĭreate these two users, and use the - no-create-home and - shell /bin/false options so that these users can’t log into the server. Step 1 - Creating Service Usersįor security purposes, we’ll begin by creating two new user accounts, prometheus and node_exporter. In previous article we successfully installed prometheus serwer.

Well, I hope this helped many out with finding information about quickly changing the node exporter port. Note: Remember if you are running in Azure or AWS that you will need to open up firewalls as well. You should be able to navigate to your Prometheus targets and see the active target. Once you have made the change then restart the service by running: sudo systemctl restart prometheus Yes, there are several nodes on the setup that I have, but in particular, you can see the 7676 port. Modify the port with the endpoint with something like the following: - job_name: 'node_exporter' static_configs: - targets: Mine will look like this: sudo vi /etc/prometheus/prometheus.yml Go to the configuration file and edit it. Now we need to tell Prometheus where to grab the configuration from for the server. Now check that the service is running on the new port by running: curl If everything works ok then you will see the metrics being gathered from the API. Now restart the node_exporter by running: sudo systemctl restart node_exporterĬheck the status of the service by running: sudo systemctl status node_exporter Of course, we change the service so now run the following to reload the configuration change: sudo systemctl daemon-reload If you are new to vi then you just type in escape, add :wq! (which stands for Write and the Quit). Of course, you can make this any more you like. I did this to make sure that the web.listen-address for the Node_Exporter is on 7676. Notice that I added the following to the ExecStart: -web.listen-address=: Now add the following: ExecStart=/usr/local/bin/node_exporter -web.listen-address=:7676 So I will be using vi and editing the service like so: sudo vi /etc/systemd/system/node_rvice I currently have my service located at: /etc/systemd/system/node_rvice

Change the Prometheus Configuration File.

There are two main changes to make this work: So for that case, I need to change the Node Exporter port. Well in my case I have a Weblogic Server that already utilizes port 9100 for services and well I probably need to allow that to run. So let's first understand why do I need to change the Node Exporter port. If you know my article then you know how I like to make things short and sweet. This will give more information on how I am installing it. If you are installing the node exporter then you can read my article here. If you are reading this then you probably are well aware of this. The Node Exporter is a service from Prometheus that allows for the extraction of node information via an Application Program Interface (API).
