hi,
Excuse me, what do you understand about "realtime"?
If your daemon examines the logfile in "realtime", the fasted way to
transport the results to nagios would be using the NSCA-Sys.; the
nsca-script transfers the results to the NSCA-Daemon running on your
Nagiosserver, and the nsca-daemon pushes the results into the
nagios.cmd-file (as far as i understood).
The NRPE-Daemon is called passivly by the Nagiosserver to execute some
plugin, so your time-intervals to get results are normally far away from
"realtime".

Hello all,
this is my first time posting to this list. I'm trying to create a custom
plugin that monitors an applications log file in real time.
I'm unclear as to whether or not I can do this explicitly with a plugin (the
real time aspect).
I'm running a Nagios 2.x management console that's getting data from a
production Linux system running nrpe. The real time monitoring needs to run
on the production box.
I'm trying to create the plugin (using Perl as my language) thus;
1. Create a daemon that actually monitors the log file.
2. On a specific event, the daemon will write status information to a data
file.
3. The plugin will read the data file at a specified interval and send it
back through the nrpe daemon to the nagios console.
Is this the right way to go about it? I don't quite see how to merge the
steps so that the plugin does all of the functionality in one program.
Since the code needs to run in real time, for example, I can't output any of
the Nagios error codes since the daemon never quits unless the entire system
goes down.
Thanks for your help.
