What is Grafana Dashboard?

• A Grafana dashboard is a web-based visualization tool that allows you to visualize data from a variety of sources, including metrics, logs, and traces. Dashboards are made up of panels, which are individual visualizations that display data in different ways, such as graphs, charts, and tables.

• Grafana dashboards are highly customizable, and you can use them to create dashboards that meet your specific needs. For example, you can create dashboards to monitor your infrastructure, track your application performance, or analyze your business data.

Why do we need Grafana Dashboard?

• Easy to use: Grafana dashboards are easy to create and use, even for users with no prior experience with data visualization.

• Powerful: Grafana dashboards offer a wide range of features and functionality, including the ability to create complex visualizations, drill down into data, and set alerts.

• Flexible: Grafana dashboards can be used to visualize data from a variety of sources, including metrics, logs, and traces.

• Open source: Grafana is an open-source project, which means that it is free to use and modify.

Task: Build your own Grafana Dashboard.

• Before building the Grafana Dashboard, we need to install the Grafana in our system or on the cloud.

• For detailed installation steps, please visit my Day 73 Blog for complete steps on how to Install Grafana on AWS EC2.

• Blog Link: Grafana Installation on AWS EC2 Instance

• After installing Grafana, we need to configure Grafana Loki and Promtail to collect the logs from the system which I have already explained in my Day 75 Blog.

• Blog Link: Grafana Loki and Promtail Setup

Let's create a Nginx & Docker Visualization in the Grafana Dashboard.

• Step-01: Install Nginx on EC2 Instance.

sudo apt-get install nginx -y

• Step-02: Click on Add Visualizations and then select the varlogs and then click on the Operation and the select Rate Count and then click on Apply.

• Thus it show how many times Nginx is called in the last hour.

• Step-03: So Now we will add this Nginx logs to Visualization.

• Step-04: Now if we want logs from Docker.So do the similar steps as we did for Nginx.Thus we have Docker logs to Visualization.

• Step-05: See the Dashboard of Grafana Loki which have varlogs, Nginx and Docker logs.
