$DESCRIPTION = "Nagios Plugin to check MapR node heartbeats to CLDB via the MapR Control System REST API

By defaults checks all nodes for heartbeat age > 3 (--heartbeat-max). Can restrict by --cluster.

Alternatively check a single --node heartbeat age against the warning/critical thresholds.

Tested on MapR 3.1.0 and 4.0.1";
