<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Hello all, I have Nagios running on my system currently. I purposely shut down one of my sites and Nagios to monitor it. From the browser it's telling me that there is a problem which is ok for me but it does not send me a mail. I checked nagios log and this is what I saw 1282660775] SERVICE ALERT: seamfix;HTTP;CRITICAL;HARD;4;HTTP CRITICAL: HTTP/1.1 503 Service Temporarily Unavailable - 616 bytes in 1.649 second response time [1282660775] SERVICE NOTIFICATION: nagiosadmin;seamfix;HTTP;CRITICAL;notify-service-by-email;HTTP CRITICAL: HTTP/1.1 503 Service Temporarily Unavailable - 616 bytes in 1.649 second response time Is there any other thing I need to set on my OS (am using Cent OS) to get the mail to start working.

I want to know whether Nagios would report that the site is down if for instance Apache Tomcat or the db service is not running. If the services are on a Windows server, you can check whether they are up either using an SNMP query ( the check_snmp_win plugin which you'll find at <a href="http://nagios.manubulon.com/" target="_blank">http://nagios.manubulon.com/</a> ), or if you would prefer not to use SNMP, then look at the NSClient++ agent for Nagios at <a href="http://nsclient.org/nscp/" target="_blank">http://nsclient.org/nscp/</a> . For simple web sites you can use check_http to test that the web page is up and running too. If you want a head start in understanding how the various plugins, agents and add-ons for Nagios fit together, I recommend the book "Nagios" by Wolfgang Barth published by No Starch Press. It gives a really good explanation from first principles and goes in to plenty of detail too. ------------------------------------------------------------------------------ Sell apps to millions through the Intel(R) Atom(Tm) Developer Program Be part of this innovative community and reach millions of netbook users worldwide.
