Hello @sandeep_reddy,
I completely agree with @Damo. Environment Manager allows you to monitor the postgresql database (WIP database), and also to test the connection of a user to the database, so not only the availability of the port for the service.
If your company has got any other enterprise-level monitoring tool, they can use ir as well to monitor the port, to test the connection to the database, etc, and send alerts if needed, and even trigger commands under certain conditions.
