[Nagios-users] No notifications while restarting any services on remote host
Hi, When i restart any services on the remote client For example tomcat application server running on port 8080. I dont get any notifications or alerts. Just want to understand the technique is it because of the normal_check_interval 5 configured in services.cfg and interval_length=60 defined in nagios.cfg. Please explain.

When you restart something like a tomcat server, it takes to short a time for Nagios to notice. If you want a notice when something is restarted, write a script that checks the root PID of the process and make this generate an email. I don't Nagios is very well suited for this operation, but a small script written in your favourite language can do it without much problems. Example: --- $ cat pidcheck.sh #!/bin/sh PIDDIR=/var/pidcheck PIDFILE=$PIDDIR/$1 [ -d $PIDDIR ] || mkdir -p $PIDDIR thispid=`pidof apache2 | cut -d -f1` if [ ! -f $PIDFILE ] then echo -n $thispid $PIDFILE exit 0 fi # implicit 'else' oldpid=`cat $PIDFILE` if [ $thispid -ne $oldpid ] then echo New pid for $1: $thispid echo -n $thispid $PIDFILE exit 1 else exit 0 fi # $ ./pidcheck.sh apache2 $ ./pidcheck.sh apache2 $ sudo /etc/init.d/apache2 restart * Restarting web server apache2 ...done. $ ./pidcheck.sh apache2 New pid for apache2: 3125 $ echo $? 1 $ ./pidcheck.sh apache2 $ echo $? 0 -- Roy Sigurd Karlsbakk (+47) 97542685 / 98013356 r...@karlsbakk.net -- I all pedagogikk er det essensielt at pensum presenteres intelligibelt.

Please explain. Thanks and Regards Kaushal With those settings, Nagios will check the service every five minutes. If you restart the service in between those checks, Nagios will not notice. Even if Nagios does notice, it won't send you a notification until the specified number of retries specified by max_check_attempts. Make sure notifications are enabled, and that you have the correct notification_options set. A common error is accidentally to set the n option in notification_options which disables all notifications for that service. Another parameter which can have an effect on whether notifications are sent (new in 3.0 Nagios) is first_notification_delay. I assume you are using the check_http plugin, as you haven't said. If you want to be notified even for very short duration outages, you're probably best off checking the event log and/or one or more of the tomcat logs too. hth, Jim -- This SF.net email is sponsored by: High Quality Requirements in a Collaborative Environment.
