I am just starting out with mon (on AIX) and have run some examples
using fping.monitor and mail.alert.
I am planning to monitor some application servers on a datacenter with
a custom monitor plugin. I want to have another monitor running at a
remote location to monitor the main monitor at the datacenter (and
vice-versa). It looks like I should use mon traps in heartbeat mode.
How do I create the heartbeats. It looks like I should use a monitor
plugin for this purpose, since it will then verify that mon is
executing the plugins. But I must be missing something, since I would
expect there to allready be a hearbeatsend.monitor included in the
package.
Below is a stab at what that part of the configuration would look like,
with my assumptions in the comments. The other monitor would have a
simmilar configuration with the trap being sent and watched reversed
from this one.
Is this the way to go?
Do I need to write my own heartbeatsend.monitor?
#--------------------------------------------------------------------
# This section defines the heartbeat mechanism. A sender and a
receiver
# This area is not explained too clearly in the mon documentation!!!
# The mon framework has a built in monitor for traps (note none is
specified in the service section).
# When a mon trap of type <watch>:<service> is received it is routed to
the coresponding watch section.
# I don't see a built in sending mechanism, nor a supplied "monitor"
for generating the hearbeat traps,
# so I will create heartbeatsend.monitor that uses the perl trap api to
send it.
# The heartbeatsend.monitor does not require any alert. If it fails,
the other side won'nt get it, and report.

# This checks for the heartbeat trap from the other monitor every
traptimeout
watch trap-heartbeat
service FromBackupMon
traptimeout 2m
# no monitor needed, handled by framework
period wd {Mon-Fri} hr {8am-5pm}
alert mail.alert [EMAIL PROTECTED]
# This sends a heartbeat to the other monitor every interval
watch trap-heartbeat
service FromMainMon
interval 1m
# This sends a mon heartbeat as trap trap-heartbeat :
FromMainMon to the main monitor
monitor heartbeatsend.monitor
# no alert required

Thanks in advance for any advice,
