Has anyone completed additional debug on hostmon null alerts?
I too have found problems with hostmon similar to what Rusell reported
back
in March. I have monitors based upon the hostmon script that I am
recycling.
The scripts give null information on reporting monitor, device and
variable.

Discussions locally suggested that there may be some interaction near
the polling time. Dumping various datafiles reveals no exact match,
( ../bin/display_snips_datafile hostmon-output) but does indicate some
problems with 'unknown' state variables on startup. The only place that
I see null device/agent are hostmon,snmpmon, and dhcpmon (recycled
hostmon).
The times are the same for all 3 monitors. Could there be a race
condition,
or deadlock on resources common to all of the above?
