PostgreSQL, also known as Postgres, is one of the world's most popular relational database management systems. It is a free and open-source relational database management system emphasizing extensibility and SQL compliance. It was originally named POSTGRES, due to its origins as a successor to the Ingres database.

Millions of developers rely on PostgreSQL as their transactional data store to drive application health and decision-making. Developers can use their SQL experience to quickly leverage PostgreSQL's capabilities as a fast, functional, and powerful data resource.

Why monitor PostgreSQL

It is important to monitor your PostgreSQL database — as the transactional store for our important applications — in order to maintain its health. Monitoring your PostgreSQL database helps you identify issues as well as help to continuously improve the database’s performance. The typical way to monitor your PostgreSQL database is to collect metrics from the operating system and the database itself.

How to use PostgreSQL Monitoring Template

Once your InfluxDB credentials have been properly configured in the CLI, you can install the PostgreSQL monitoring template using the Quick Install command. Once installed, the data for the dashboard will be populated by the included PostgreSQL Telegraf configuration, which includes the relevant PostgreSQL Input. Note that you might need to customize the input configuration to better serve your needs, including by specifying a new input value. All of this will depend on how your organization is currently running PostgreSQL.
