Check various hardware environmental sensors

I'm missing performance data and i tried checking a juniper SA2500 cluster on which it doesn't work.
On Cisco equipment it does work though and i give 3 stars for basically doing what it does, i would've given 4 if performance data was generated and 5 if more tresholds could be finetuned.

Hi!

Good plugin.
I found a little bug. Here is a patch for fixing it:

my %volt_status;

+if ($voltexist !=0) {
for ($i=0;$i

Excellent script, its huge.

Thanks a lot for sharing and taking your time to make this.

However can you explain to me how i am able to see what the exact temperature is?

Example:./check_snmp_environment -H pgpa0sw1 -C netstat -T cisco -c 10
3 Fan OK, 2 ps OK, 10 temp OK : OK

I only get ok's but would like to know the exact temperature.

I have added support for netscreen internal temperature sensors. Plaese find the patch in your email box.

Thanks a lot for your work!

I wrote a small patch. Added state PSUs "PowerOff".

I have loaded the check_snmp_environment plugin and I believe that I have loaded the correct MIB (CISCO-ENVMON-MIB). Currently I get the following error when I test the following service check

Check: check_snmp_env -H $HOSTADDRESS$ -T cisco -l netmanager -x N0GUe5$MD5HPS -X N0GUe5$DESHPS

Error: ERROR opening session: Received usmStatsWrongDigests.0 Report-PDU with value 36 during synchronization.

I'm using SNMP v3.

Thanks for sharing this plugin. We're using it to monitor a few dozen Cisco switches. It was very simple to deploy and has accurately identified problems.

Very Good!

Very good and comprehensive, love this check.

We did however change the OID for the Extreme_ps_status to the next .1. as we have only 1 power supply connected in the switches it was returning an warning on the second supply.
Around line 273
#my $extreme_ps_status = "1.3.6.1.4.1.1916.1.1.1.27.1.2";
# only want PS one. DA 6/5/2011
my $extreme_ps_status = "1.3.6.1.4.1.1916.1.1.1.27.1.2.1";

I'm sure someone can do a more elegant solution however this works for us ATM.

This plugin enable us to start monitoring the various components of our Juniper devices mostly Juniper MX960.
Setting up the plugin in Nagios Version 3.2.3 is straight forward the only problem i faced was plugin works fine from command line but giving error 'Service check did not exit properly', quick googling reports its something to do with embedded perl. simple fix it to prefixes the command_line with full path to the perl. The command definition look like...

define command{
command_name check_snmp_components
command_line /usr/bin/perl $USER1$/check_snmp_environment.pl -H $HOSTADDRESS$ .....
}

Tested using Nagios 3.2.0 running on Ubuntu 10.04LTS checking various Cisco gear (6509, 2940, etc).
