A Guide to Monitor Linux Server using Prometheus and Grafana

On this tutorial I’ll discuss Prometheus and Grafana. You’ll study to put in each on CentOS/RHEL and perceive methods to use Prometheus and Grafana to observe the Linux server.

Introduction

Grafana is a number one time collection, open supply platform for visualization and monitoring. It means that you can question statistics, visualize them, arrange alerts and get insights, no matter the place they’re saved. You may create nice dashboards in Grafana to visualise and monitor the statistics.

Prometheus is an open-source time collection monitoring system for machine-oriented and extremely dynamic service-oriented architectures. It might probably monitor actually every part. It integrates very easily with Grafana as Grafana additionally affords Prometheus as certainly one of its knowledge sources.

If you happen to’re a beginner, I like to recommend studying an introduction to the Prometheus and Grafana article.

I am going to present you methods to set up them on CentOS. You have to have a minimum of 2 GB of RAM. You should buy a cloud server from DigitalOcean to check out.

Set up Prometheus

Step 1: Obtain Prometheus

Obtain the most recent Prometheus Linux bundle from the official web page.

Examine the official launch web page to get the most recent launch.

Step 2: Configure Prometheus

Create a brand new consumer Prometheus utilizing the command beneath.

[centos@geekflare ~]$ sudo useradd -s /sbin/false prometheus

Give all possession of the Prometheus file to the Prometheus consumer. Make all information executable within the specified path.

[centos@geekflare ~]$ sudo chmod 755 prometheus-2.18.1.linux-amd64 -R
[centos@geekflare ~]$ sudo chown prometheus:prometheus prometheus-2.18.1.linux-amd64 -R

It is time to configure Prometheus as a service inside the system. Create a file prometheus.service and put the traces beneath into the file and put it aside.

[centos@geekflare ~]$ sudo gedit /and so on/systemd/system/prometheus.service
[Unit]

WantedBy=multi-user.goal

Step 3: Launch Prometheus

Utilizing systemctl, reload the systemd system and begin the Prometheus service. The standing ought to point out that the service is working if you happen to adopted all of the steps accurately.

[centos@geekflare prometheus]$ sudo systemctl daemon-reload
[centos@geekflare prometheus]$ sudo systemctl begin prometheus.service
[centos@geekflare prometheus]$ sudo systemctl allow prometheus.service

Set up Grafana

Step 1: Add Grafana Repo

By default, the Grafana repository will not be current in CentOS repositories, so you could add it. Create a file grafana.repo inside /and so on/yum.repos.d/ and add the traces beneath.

[centos@geekflare ~]$ sudo gedit /and so on/yum.repos.d/grafana.repo

[grafana]

Step 2: Set up Grafana

Replace CentOS and set up the Grafana bundle.

Step 4: Open the Grafana Internet UI

As soon as the service is up and working, entry the server’s IP tackle with port 3000 to entry Grafana’s internet interface. For the primary time you could use administrator as username and password; You’ll then be prompted to set your personal password.

Set up Node Exporter

node_exporter is an official bundle that should be put in on Linux servers with a view to be checked. It reveals a number of {hardware} and working system stats, which will probably be retrieved by Prometheus and finally visualized on Grafana.

Step 1: Obtain Node Exporter

Use wget to obtain the node exporter bundle in your server.

Examine the discharge web page for the most recent model

Add server to Prometheus

Step 1: Edit prometheus.yml

You have to add a brand new activity to the prometheus.yml file. Open a brand new tab within the terminal and edit the file as listed beneath.

[centos@geekflare ~]$ sudo gedit prometheus.yml

- job_name: 'node_exporter'
static_configs:
- targets: ['localhost:9100']

Word: Above I configured the localhost within the goal as a result of I need to monitor the Prometheus server itself. You may change this to the IP tackle of the particular Linux server. Port 9100 is the default port of node_exporter.

Step 2: Stop and launch Prometheus

[centos@geekflare]$ sudo systemctl cease prometheus.service
[centos@geekflare]$ sudo systemctl begin prometheus.service

Step 3: Examine objectives

Go to https://localhost:9090/targets; you will note targets are energetic, one will probably be a node exporter.

Combine Prometheus into Grafana

Now that Grafana and Prometheus are put in. let’s use them for monitoring servers.

  • Go to Grafana dwelling and click on on the settings signal on the left. Then click on on ‘Information Sources’.
  • Click on Add knowledge supply and choose Prometheus.

  • Set the URL because the IP tackle of the Prometheus server with port 9090. On this instance, I am utilizing Prometheus and Grafana on the identical server, so it could be http://localhost:9090.
  • Click on Save and Take a look at. You get successful message when the information supply is added.
