How to make parallel processing rather than serial processing ??
Hello everybody,
I have a little problem with one of my program. I made a plugin for collectd (a stats collector for my servers) but I have a problem to make it run in parallel.
My program gathers stats from logs, so it needs to run in background waiting for any new lines added in the log files.
My problem is that I call my program in a bash script that tails my log files, like this :
The problem is that it does not work very well. So I would like to make the "tail -f" parallel processing directly in my perl program.
Here is the perl program (collection.pl) I'd like to make parallel processing with :
I have seen that parallel processing could be done with fork or something like that but I don't really understand how to do it. Does anyone has an idea of how I could do that ?

COLLECTDMON(1) collectd COLLECTDMON(1)NAME
collectdmon - Monitoring daemon for collectd
SYNOPSIS
collectdmon [options] [-- collectd options]
DESCRIPTION
collectdmon is a small "wrapper" daemon which starts and monitors the collectd daemon. If collectd terminates it will automatically be
restarted, unless collectdmon was told to shut it down.
OPTIONS
collectdmon supports the following options:
-c <path>
Specify the pathname of the collectd binary. You may either specify an absolute path or simply the name of the binary in which case the
PATH variable will be searched for it. The default is "collectd".
-P <pid-file>
Specify the pid file. The default is "/var/run/collectdmon.pid".
-h Output usage information and exit.
collectd options
Specify options that are passed on to collectd. If it is not already included, -f will be added to these options. See collectd(1).
SIGNALS
collectdmon accepts the following signals:
SIGINT, SIGTERM
These signals cause collectdmon to terminate collectd, wait for its termination and then shut down.
SIGHUP
This signal causes collectdmon to terminate collectd, wait for its termination and then restart it.
