Measures reported by PgRtoTest

Recovery Time Objective is a metric that helps to calculate how quickly you need to recover your Application, database and other services following a disaster (crash) in order to maintain business continuity. If data and infrastructure are not recovered following a disaster within the time duration set for the Recovery Time Objective, then, businesses could suffer irreparable data loss and integrity. In a high availability setup, if the replica server is not restored within a shorter duration, the data in the master may not be in sync with the replica server. To avoid such unpleasant eventualities and to ensure that their business is back to normal in a very short duration, administarators may have to periodically keep track on the RTO of the target PostgreSQL server. The PgRtoTest test helps administrators in this regard!

In a high availability setup where the target database server is a replica server, this test reports the Recovery Time Objective i.e., replication lag duration (the time lag between the master and the replica server). Using this test, administrators can gain a fair knowledge on how long they can manage their business post a disaster/crash of the replica server.

Note:

This test will report metrics only if the monitored target PostgreSQL database server is a replica server in a high availability setup.

Outputs of the test : One set of results for the target PostgreSQL server
