Re: [Nagios-users] start a script automatically
Hi,
I just did this a few days ago using eventhandlers, I'll post my config
for your convenience, actually, it's dead easy:
this is the config of the service check:
define service{
use generic-service ; Name of
service template to use
host_name www..be
service_description HTTP_check_www.x.be_.5_interface
contact_groups solaris-admins
retry_check_interval3
event_handler restart_xxxweb
check_command check_webtest!xxx-5.scr!http://www.xxx.be interface
.5 via internet
}
the key here is the event_handler line. This 'function' is executed
whenever a state change occurs.
in checkcommands.cfg you must define this function:
define command{
command_namerestart_xxxweb
command_line
/usr/lib/nagios/plugins/eventhandlers/restart_xweb $SERVICESTATE$
$SERVICESTATETYPE$ $SERVICEATTEMPT$
}
This provides the link to the script that will be executed each time a
state change occurs.
below the contents of this script (I found it somewhere on a nagios
support site) and modified it slightly for my environment. As you will
see, I'm using the nagios client mechanism to restart the service on the
remote host.
#!/bin/sh
#
# Event handler script for restarting the web server on the local machine
#
# Note: This script will only restart the web server if the service is
# retried 3 times (in a soft state) or if the web service somehow
# manages to fall into a hard error state.
#
# What state is the HTTP service in?
case $1 in
OK)
# The service just came back up, so don't do anything...
;;
WARNING)
# We don't really care about warning states, since the service is
probably still running...
;;
UNKNOWN)
# We don't know what might be causing an unknown error, so don't
do anything...
;;
CRITICAL)
# Aha! The HTTP service appears to have a problem - perhaps we
should restart the server...
# Is this a soft or a hard state?
case $2 in
# We're in a soft state, meaning that Nagios is in the middle of
retrying the
# check before it turns into a hard state and contacts get
notified...
SOFT)
# What check attempt are we on? We don't want to restart
the web server on the first
# check, because it may just be a fluke!
case $3 in
# Wait until the check has been tried 3 times before
restarting the web server.
# If the check fails on the 4th time (after we restart the
web server), the state
# type will turn to hard and contacts will be notified
of the problem.
# Hopefully this will restart the web server successfully,
so the 4th check will
# result in a soft recovery. If that happens no one
gets notified because we
# fixed the problem!
1)
echo $(date): Dit is de eerste soft state voor
web, we herstarten de gateway /tmp/eventhandler_test
/usr/lib/nagios/plugins/check_nrpe -H
193.110.158.5 -c restart_xxxweb
;;
2)
echo $(date): Dit is de tweede soft state voor
xxxweb, we herstarten de gateway voor de 2e keer
/tmp/eventhandler_test
/usr/lib/nagios/plugins/check_nrpe -H
193.110.158.5 -c restart_xxxweb
;;
3)
echo $(date): Dit is de derde soft state voor
xxxweb, we herstarten de gateway voor de laatste maal, indien het nog niet
werkt is er iets goed fout /tmp/eventhandler_test
/usr/lib/nagios/plugins/check_nrpe -H
193.110.158.5 -c restart_xxxweb
;;
esac
;;
# The HTTP service somehow managed to turn into a hard error
without getting fixed.
# It should have been restarted by the code above, but for some
reason it didn't.
# Let's give it one last try, shall we?
# Note: Contacts have already been notified of a problem with the
service at this
# point (unless you disabled notifications for this service)
HARD)
echo $(date): na 3x proberen wil de xxxweb gateway nog
altijd niet opstarte, misschien eens proberen met de server te rebooten ?

[Nagios-users] integrating swatch with nagios
Hi, I'm trying to integrate swatch in nagios (via passive checks, I want swatch as a reaction to a 'hit' run the submit_check_result into a passive check). But I'm having a lot of problems with the commandline parameters. for example, swatch offers the $_ parameter containing the entire line from e.g. a solaris message file. But these files then to contain characters that are interpreted by the shell such as [ and ' and whatever. Basicly, I want to search a logfile for a regular expression, and if there's a match, I want the entire line to be sent to nagios (preferrably via a passive check). I do not want to use the nagios plugin checklog because it's too kludgy for my taste. How do you integrate logfile parsing in to nagios ? I've installed SEC also (http://simple-evcorr.sourceforge.net) but it appears to be far too complex for my needs. Thanks for your input on this matter. regards, Tom. --- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.

Re: [Nagios-users] Event Handlers
Hi James, I just came accross your message on the nagios mailing list, and i have exactly the same request. I didn't see any answers on the list, so I was wondering if you have found a solution ? regards, Tom. --- Tom Van Overbeke - ABSI Service Delivery Coordinator email: [EMAIL PROTECTED] Tel: +32 2 333 40 00 - Fax: +32 2 332 34 69 website: http://www.absi.be --- Dehnert James Sr [EMAIL PROTECTED] Sent by: [EMAIL PROTECTED] 10/03/2006 23:29 To: nagios-users@lists.sourceforge.net cc: Subject:[Nagios-users] Event Handlers Most of all of the processes and such I monitor are not on the Nagios server. I do want to be able to use event handlers to try and resolve things before I get paged though, so I am wondering if there is a plug-in that can be used through NCSA or NRPE that will allow me to run an event handler script on a remote system.
