OmniPITR module

Add support for counting Linux Process types

support for HOSTS ALLOW/DENY in resmon.conf and fix regexp check in nagios plugin to match '^$'

Fix redhat init script

Uses ps to count the amount of processes on a system. I've placed this
into the Linux area as I've only tested it on a Linux system (Ubuntu
11.04).

To avoid warning messages like:
"Use of uninitialized value $bits in string eq at /opt/resmon/lib/Resmon/Config.pm line 16..."
$bits variable should be checked if it is defined before comparison with empty string

When ./check_resmon_metric -H myhost -M Core::Fmadm -C failures -m resources -r '^$'
Use of uninitialized value $value in pattern match (m//) at /etc/nagios3/CS.conf.d/check_resmon_metric line 378.
Use of uninitialized value $value in concatenation (.) or string at /etc/nagios3/CS.conf.d/check_resmon_metric line 383.
OK: resources -
To avoid false critical status check if $value is not defined and if so define as empty string

Hosts allow-deny lists are the coma or blank separated lists of
a dotted decimal IPv4 addresses of the form a.b.c.d. to match incoming machine’s IP address exactly,
or an 'ipaddr/n' where ipaddr is the IP address and n is the number of one bits in the netmask.
The first to occur match gives the result, skipping other rules.
If nothing matches IP is allowed.

They are still available in the resmon1 branch if needed.

This module is meant to be generic enough that it can do any query based check against postgres. You just need to add the entry to %queries for it to be available.

The backslash at the end of the line wasn't a line continuation, and turned
the following string into a reference. Yay perl!

The generic Cpu module makes use a vmstat, and the columns used vary across
different linux installations. This improves the situation somewhat.

MemFreeBufCache == MemFree + Buffers + Cached

Add a module to report OS name/version.  Helpful for correlating events with OS changes like patching or upgrading.  Add a gitignore at the top level with resmon.conf in it.  This will prevent the loss of a live conf file during a git clean.

The filter patterns for identifying local port/remote port and so on are taken
directly from the resmon 1 module. They look like they could use some
improvement to prevent some misdetection, but if the resmon 1 module worked
for your purposes, the resmon 2 module should also.

If a client connection dies (connection reset by peer) then previously the web
server would just exit. This shouldn't happen.

An example of this is the resmon main page. By default this check will look
at http://hostname:81/modulename/checkname which will output a single check.
However, this change lets you specify a custom URL which returns metrics for
multiple modules and it will find the correct one.
