In our previous tutorial, we learned how to install Prometheus & gather the system data for monitoring but the data provided by Prometheus was in raw format & was not at all easy to understand. So that is where the Grafana comes into the picture.

Grafana is an open-source tool that allows us to understand the data by visualizing it. Not only can we visualize the data, we can query it or can also create alerts. Grafana can visualize the data from a number of data sources like Prometheus, Graphite, Elasticsearch, AWS cloud-alerts & many more.

install grafana

In this tutorial, we will learn to install Grafana on Linux systems & also integrate it with Prometheus to get our data visualized in nice & easy to understand dashboards.

Install Grafana

We will install Grafana by using the source package, we can download the Grafana with the following command,

$ wget

Next extract the tar package,

$ tar xvf grafana-6.4.4.linux-amd64.tar.gz

$ cd grafana-6.4.4/

Now to start the service we will execute the following command,

$ nohup ./grafana-server &

Note:- To restart the Grafana service, kill the PID of grafana & run the above-mentioned command again.

Configuring Grafana

Now that the Grafana server is up, we can configure it from our web-browser. Open the following URL from the browser,

http://localhost:3000         or       http://IP_address_of_server:3000

We will get the login screen, enter the user ‘admin’ & password ‘admin’ & we would be redirected to next screen where we would be asked to set up a new password,

install Grafana

We would then be redirected to the homepage, here we would configure a datasource i.e. Prometheus. Click on ‘Add Data Source’

install Grafana

Next select ‘Prometheus’ & press ‘Select’,

install Grafana

Next, we need to enter the Prometheus details. Once you have entered the details correctly, click on ‘Save & Test’, if details entered are correct you will get the message ‘Datasource is working’,

install Grafana

Once the datasource has been added successfully, we can either create our own custom dashboard or can use one of many dashboards available on the grafana official website. So now click on ‘+’ icon on left side on the homepage & click on ‘Import’,

install Grafana

Now we can either enter the dashboard number or the JSON for the dashboard to import it, here we will be using a dashboard numbered ‘159’ to visualize our data (Check it here

install GrafanaClick on ‘Load’ to load the dashboard & now we have named the Dashboard & select the Prometheus datasource,

install Grafana

Click on ‘Import’ & we are done. We can now see the newly created dashboard,

install grafana

There are a number of other dashboards that we can use or we can also create custom dashboards as per our own needs.

That’s it, we now end our tutorial on how to install Grafana & integrate it with Prometheus. Please feel free to send in any questions or queries using the comment box below.
