[Nut-upsuser] how do you test (nagios) that upsmon is connected?

How about using a dummy ups to set up a regular end-to-end heart beat. 
As long as the heart beats, there is no news, but if it stops, 
upssched-cmd sends out an e-mail or other warning.

In ups.conf, add

[heartbeat]
         driver = dummy-ups
         port = heartbeat.dev
         desc = "Dummy ups sends heart beat to upssched-cmd"

In heartbeat.dev, write

ups.status: REPLBATT
TIMER 300

In upsmon.conf, write

NOTIFYFLAG REPLBATT SYSLOG+EXEC

In upssched.conf, add

# Heatbeat from dummy ups every 5 minutes, re-start 6 minute timer
AT REPLBATT heartbeat CANCEL-TIMER heatbeat-timer
AT REPLBATT heartbeat START-TIMER  heatbeat-timer 360

In upssched-cmd, if heatbeat-timer completes, then send "UPS heatbeat 
failure" message to sysadmin.

If this works, let me know, and I will use it myself :-)
It would be nice to have a HEARTBEAT status instead of using REPLBATT.
