Nagios script output issue
Hi Folks,

Nagios is acting a little weird for me, I have this external script which I hooked into Nagios, it merely does a curl/wget on a URL and returns the status based on string in the content/output. Initially for 2-3 hrs the script returns the right status and Nagios reports correctly i.e. OK, WARN, ERROR based on the exit from the script. After 2-3 hrs output which was (and should be) OK or WARN starts returning CRITICAL and the output line says "Application is" and not even "Application is ERROR" or "Application is FATAL".

There is nothing in the logs to suggest what could be the problem. Have you experienced this before and let me know the corrective action. I am running Nagios on Mac OSX.

Here is the script for the curious -
Code:
#!/bin/bash

read URL < "$1"

STATUS=`curl -s $URL |grep summary|awk -F\" '{print $2}'`
echo "Application is $STATUS"
echo "curl $URL"

case $STATUS in
OK)
   exit 0
   ;;
WARN)
  exit 1
  ;;
ERROR)
  exit 2
  ;;
FATAL)
  exit 2
  ;;
*)
  exit 2
  ;;
esac

Thanks,
Jack

When I run the script on the commandline it returns the correct status.

But on nagios it shows different error.

Any clues?

Thanks,
Jack

NAME

       Nagios - network/systems status monitoring daemon

SYNOPSIS

       nagios [-h] [-v] [-s] [-d] <main_config_file>

DESCRIPTION

       nagios  is a daemon program that monitors the status of various network accessible systems, devices, and more. For more information, please
       consult the online documentation available at http://www.nagios.org, or on your nagios server's web page.

OPTIONS

       main_config_file
	      The main configuration file.  On openSUSE systems this defaults to /etc/nagios/nagios.cfg

       -h     A helpful usage message

       -v     Reads all data in the configuration files and performs a basic verification/sanity check.  Always make sure you verify  your  config
	      data before (re)starting Nagios. You can also use the Nagios init script to verify your configuration - try: rcnagios check_verbose

       -s     Shows projected/recommended check scheduling information based on the current data in the configuration files.

       -d     Starts Nagios in daemon mode (instead of as a foreground process).

FILES

       /etc/nagios
	      Default configuration directory for nagios
