NC_NET Scripts

[Anthony Montibello]

Hi Paul,

I think you need to split your issues into seperate posts,

I have not worked a lot with event Handlers in Nagios yet, so I willo not be
able to help with that,

BUt I can help on the NC_NEt side of the issue.
first, create the script,  (make sure you are using the most recent version
of NC_NEt and check_nc_Net due to a few bug fixes and other options enabled
in the most recent version.
your script should print to standard output, and should have an exit code.
make sure the script is in the Script folder of NC_NET.
IF you want to pass arguments to the script you must modify the
Startup.cfgof NC_NET in order for the Arguments to be accepted.
on a simplest case, you can try to hardcode the script as a BAT file simply
running a command like
net start xyzservice
to test the script call it using Check_nt/check_nc_net
if the script runs from the command line, then you need to start worrying
about getting the Event Handler running,
For that, make sure to read the Nagios Documentation I thought the example
was oK in it.
WHen running the event handler make sure only to run it on the proper state,
also make sure you do not have your retry interval to close together,
sometimes it takes 20 sec or longer to restart a service.  thus  int he
check_nt command make sure to have long enough timeouts for your command.

If you get the problem down to just the event handler aspect of it, then you
may want to repost with a new subject and description for just the event
handler.

good Luck,
Tony (author of NC_NEt)
