The Canadian Light Source (CLS) PV Monitor provides system status for the CLS EPICs network, which consists of some 370,000 PVs hosted by 950 EPICs Applications running on 400 IOCs. The existing EPICs beacon, while useful, does not fully expose system status. We present an EPICs "heartbeat" that requires a 1-line code change in any EPICs Application. The CLS PV Monitor is able to determine instantaneous PV status for every PV hosted by a heartbeat-enabled EPICs Application, negating the need for database crawling or PV scanning. So far, the heartbeat has been rolled out to 40 CLS EPICs Applications.
