One thing that I love about Prometheus is that it has a multitude of Integration with different services, both officially supported and the third party supported.
Let's see how can we monitor MySQL with Prometheus.

Those who are the starter or new to Prometheus can refer to our this blog.

MySQL is a popular opensource relational database system, which exposed a large number of metrics for monitoring but not in Prometheus format. For capturing that data in Prometheus format we use mysqld_exporter.

I am assuming that you have already setup MySQL Server.
Configuration changes in MySQL For setting up MySQL monitoring, we need a user with reading access on all databases which we can achieve by an existing user also but the good practice is that we should always create a new user in the database for new service.
CREATEUSER 'mysqld_exporter'@'localhost' IDENTIFIED BY 'password' WITH MAX_USER_CONNECTIONS 3;
After creating a user we simply have to provide permission…

The CI process in GitLab CI is defined within a file in the code repository itself using a YAML configuration syntax.
The work is then dispatched to machines called runners, which are easy to set up and can be provisioned on many different operating systems. When configuring runners, you can choose between different executors like Docker, shell, VirtualBox, or Kubernetes to determi…
