The nagios plugin that you find in the package nagios-plugins-snmp was insufficient for my needs in a new nagios deployment. The biggest reason that it was insufficient was that it gets integer values, and then can only issue a warning or alert if that integer value is GREATER than what value you gave it. The deployment I’m setting up required that the values could be checked against a range, which is necessary when receiving SNMP data from a thermometer or hygrometer. This plugin supports receiving a range of values to check against, and then it returns the appropriate exit code.

I’ve written a tad bit of documentation in the top of the file, but here it is again, in block quotes! Download link is just below the block quote area.

# This script written with haste by Benjamin Rose, July 8th 2009 @ 11:45:42 AM
# It was written because the check_snmp plugin provided by the nagios package
# does not support range matching. It can check if the snmp value is greater than
# a given number but not less than, nor a range consisting of either a high value
# or a low value. Hence, this script, given a mode of 1 and a good range with
# which to work, will report back appropriately.
#
# Modes:
# 1 = Number comparison, reports on a given range. Argument order given in
# the usage statement.
# 2 = String comparison, which for now is just “Open” or otherwise.
#
# TODO:
# 1) Change the order of the arguments, putting mode in front of the
# variables, and then change the usage based on the given mode.
# 2) Allow the user to configure which strings are “good” and which are “bad”.

Plugin link: [snmp_plugin_wrapper]

It exists! It’s not in the Adobe yum repos yet, as it’s still an alpha build, but you can download it here:

[Native Linux 64-bit Flash Player from Adobe Labs]

It works very well. No longer do you need to get nspluginwrapper working, and then configure pulseaudio (if that’s your distro) to listen to 32-bit apps, blah blah blah. Simply unpackage, throw the .so file into the firefox plugins directory, and restart firefox. Great stuff. I’ve also noticed there’s a performance gain to be seen, my flash videos used to lag and flicker on youtube when I made them fullscreen, and this doesn’t happen anymore. Sound worked out of the box with pulse.

And the best part, although it’s supposedly an alpha build, it crashes a heck of a lot less than it used to. No more npviewer.bin segfaults in the /var/log/messages file! My guess is that this is because of the lack of a hacked wrapper. But, that being said, if it crashes on you a lot after trying it, don’t be too upset. At least they’re trying.
