The HeartbeatTrans Transformer is a simple transformer which can be configured to monitor an individual message channel. If there isn't any alerts after the set amount of time, it will create an alert in BES.
This is simple to configure you just need to create a config file in $PPHOME/cfg. An example of this config file can already found in $PPHOME/cfg/HeartbeatTrans.cfg. You can set up the match globally on the message channel or matching on particular parts of an alert.
