Re: Monitor a wireless network
Doesn't matter I worked it out.. I think.
Testing the attached now. If anyone wants to glance it over it feel free to
give feedback. Please excuse my rusty Perl.

Monitor a wireless network
Hi All,
I'm new to mon but its working great monitoring several servers for me already
with fping.
In the past I have noticed my wireless network stops broadcasting the SSID at
times and I would like to detect when this happends (so I can reboot the AP).
What I need your help with is with writing a mon monitor script. I haven't
seen any information on the input/output required to interact with mon. I
believe its as simple as the below but any pointers would be appreciated.
If your script exits with state 1 = error
If your script exits with state 0 = ok/normal
Any information printed before exit is printed in the mon report.
So something along the lines of
foreach $interface (@ARGV) {
do my testing here for each interface passed to the mon script
}
if (@failures) {
print @failures
exit 1;
}
exit 0;
Is that all there is to it, any hints/tips ?
Regards,
Lee
p.s. Sorry about the bad pseudo code :)
