On some systems, there are lines in /proc/meminfo that don't match the regex.
Currently these cause resmon to throw an error and give a blank metric. This
change skips those metrics rather than throwing an error.

value to determine whether to use cache_command or run_command.

report its output.

Allow setting an absent => X config param for file checks.  If set will return all the metrics the module normally would, but with their integer values set to whatever you defined for absent.  present will still = 0 and text values will be undef

This allows you to have multiple checks on the same file, but with a different
match string in order to count different types of errors.

Allow escaped commas in config parameters.  Update Core::SMART docs and stop prefixing metrics with the disk name, as Resmon already uses check_name in the final metric output.

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).

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.
