If you are just having trouble with launching net monitor after Ha fail-over then make sure any left over pid files in each site ($HCISITEDIR/exec/hcimonitord/pid) got cleaned up before trying to start the net monitor.
In fact, probably a good idea to check for any left over pid files for each site after fail-over before launching anything
cd $HCISITEDIR; find . -name pid 2>/dev/null
