Re: [monit] Executing external script with monit

[ChetanK]

HI,

I am facing the same problem as first reported. After trying everything, I
finally specified the actual command in the "exec" block. Here is what I
have in the monitrc file (send a SNMP trap when memory usage exceeds 21%):

  check system myUbuntusystem
#    if loadavg (1min) > 4 then alert
#    if loadavg (5min) > 2 then alert
    if memory usage > 21% then exec "/usr/bin/snmptrap -v 1 -c public
localhost TRAP-TEST-MIB::demotraps 10.9.225.57 2 0 rr IF-MIB::ifIndex i 1"

Here I am specifying the "path" to the snmptrap program. The same command
when issued verbatim in a terminal window or a bash script (when invoked
manually) works just fine.

Any help will be really useful. If I do need to setup env variables, which
ones should I be setting? Also, if I specify this command in a script, do I
need to do anything special in the script?

Regards,
Chetan
