Vedr.: Re: checking for reboots of a host

[Thomas Jens Lauritsen]

Hi List,

I use this snmp-script....


#!/bin/sh
#
# check_booted.sh via SNMP
#
# Autor         : Thomas Jens Lauritsen <tjl at topdanmark.dk>
# Date          : 4. june 2004
# Version       : 1.0
# Description   : Script that checks if a box just has been booted via
SNMP.
# Req.          : The script uses the bc - calulator (Installed on most
*nix's)
# Advice        : Run the script for every 60 min - to keep the load down
on the cpu.
# Nagios        : In the services.cfg. Exampel:
check_booted.sh!public!100!1000!
# Info          : You have to change Oid for your system - see below (num1
and num2).
#
#                                                     crit  warn
# ./check_booted.sh <ip-address> <public> <100> <1000>
#
# Verify that there is an input
# ------------------------------
#
if [ -z "$1" ]; then
echo "usage  : check_booted.sh <hostname> <snmp-community> <crit-num1>
<warn-num2>"
echo "example: check_booted.sh 192.168.1.1 public 2 2 100 1000"
