How to use the heartbeat functionality

The heartbeat functionality in TM Master v2 helps you keep track of when the office last received replication data from the replicating units in your fleet. This is a vital tool for administrators tasked with overseeing and troubleshooting the replication of data from units to the office.

It works by having each replicating unit send an extremely small file with a timestamp to the office each replication interval. Once received on the office side the timestamp is entered into the database and can be viewed in the "Last heartbeat" column under [Fleet -> Units].

For an explanation of the heartbeat symbols please see https://support.teromarine.com/en-us/article/205-what-do-the-different-heartbeat-symbols-mean

The heartbeat functionality can be customized for each individual unit, and it's possible to set up automated notifications of replication downtime. To access these settings please go to [Fleet -> Units], double click the unit you want to set up and go to the "Heartbeat" tab.
