Uptime is pretty easy. CPU and Storage are well handled by these plugins:
http://nagios.manubulon.com/
Here's braindead (positional parameters, Oh My!) simple plugin for sysUptime
that is useful if you want to know when the uptime crosses some threshold:
#!/usr/local/nagios/bin/perl
use warnings;
use strict;
use Net::SNMP;
my ($session, $error) = Net::SNMP->session(
-hostname => shift || 'localhost',
-community => shift || 'public',
-port => shift || 161
);
my $criticaldays = shift;
if (!defined($session)) {
printf("ERROR: %s.\n", $error);
exit 1;
}
my $sysUpTime = '1.3.6.1.2.1.1.3.0';
my $result = $session->get_request(
-varbindlist => [$sysUpTime]
);
if (!defined($result)) {
printf("ERROR: %s.\n", $session->error);
$session->close;
exit 1;
}
my $uptime = $result->{$sysUpTime};
$session->close;
if ($uptime =~ /(\d+) days/) {
my $daysup = $1;
if (defined $criticaldays and $daysup > $criticaldays) {
print "UPTIME CRITICAL: >$daysup days. Too long, reboot\n";
exit 2;
} else {
print "UPTIME OK: $uptime\n";
}
} else {
print "UPTIME OK: $uptime\n";
}
exit 0;
So your command definition looks like:
/usr/local/nagios/libexec/check_snmp_uptime.pl $HOSTADDRESS$ $USER21$ 161 720

Subject: [Nagios-users] Nagios SNMP Plugin
Anyone out there have any examples of using Nagios SNMP plugin to perform
simple queries for Cisco Routers and Linux boxes? I'm thinking of basic
queries such as uptime, cpu, storage, etc..
I was thinking of using the check_snmp cmd, but syntax is a bit confusing...if
you know of a better way that would be helpful too.
Thanks!
