Check stack status of Netgear switches
(Count in SNMP the physical number of units in the stack)
Script usage:
$0 -H host -e [-c community] [-v version]
[-s 'any_snmp_args'] [-V] [--help]

Options :
-h, --help This help
-H, --host Checked switch virtual IP
-c, --community SNMP MIB (default = public)
-e, --expected Expected switches count
-p, --port SNMP port (default = 161)
-s, --snmp-args Any SNMP args you d'like to add to snmpwalk command
(credentials for SNMPv3, or whatever)
-v, --version SNMP version (default = 2c)
-V, --verbose Verbose output, mainly for debugging


Example: check for 2 switches in stack:
check_stack_netgear.sh -H 1.2.3.4 -e 2


Nagios definition example:
define command{
command_name check_stack_netgear
command_line $USER1$/check_stack_netgear.sh -H $HOSTADDRESS$ -e $ARG2$
}
define service{
use generic-service
host_name Switch-XXX
service_description Stack with 2 members
check_command check_stack_netgear!2
}


How it work:
It simply perform a snmpwalk on ENTITY-MIB:entPhysicalEntry (OID 1.3.6.1.2.1.47.1.1.1.1.7), search for 'Unit' devices and count them.
Reviews (2)
I added nagios performance data and check for errors, multicast, unicast and octetcs. Enjoy.

#!/bin/bash

##
#
# receive statusinfo from netgear switches
#
# you can get all snmp-options with:
# snmpwalk -m ALL -v 2c -c MYCOMMUNITY MYIPADDRESS .1.3.6.1.2.1
#
#
# Usage:
# ./check_netgear_switch -h IP-ADDRESS -c SNMP-COMMUNITY -s STATUSCHECK

Hi there,
than you for the script

I have this output with GS748TS http://pastebin.com/6xePiCqn


Could you add in the script to count the "Slot" if doesn't find the "Unit"



thank you again
