<tt>Hello Alejandro, </tt> <tt>first of all: please do not "toppost" and "fullquote" the messages.</tt> <tt>It's considered rude and makes reading and understanding your message</tt> <tt>harder then necessary. Thanks for your understanding.</tt> <tt>Second: You have misunderstood something.</tt> <tt>You posted a service definition.</tt> <tt>> --- > define service{ [snip]</tt> <tt>> } > --- </tt> <tt>But you then posted a host problem notification.</tt> <tt> > at 13:20pm > Notification Type: PROBLEM > Host: cn016 > State: DOWN </tt> <tt>Service problems and host problems are two different things.</tt> <tt>The fact that you have a PING service might be the reason</tt> <tt>you misinterpreted the mail. A PING service is most of the time</tt> <tt>not necessary, because Nagios will ping the host anyways</tt> <tt>via the check-host-alive command.</tt> <tt>> How i can make to receive only one alert? </tt> <tt>Check your host definition for the notification_interval.</tt> <tt>Regards</tt> <tt> Sascha</tt> -- Sascha Runschke IT-Infrastruktur fon : +49 (201) / 102-1879 fax : +49 (201) / 102-1102105 mobil : +49 (173) / 5419665 GFKL Financial Services AG Vorstand: Dr. Peter Jänsch (Vors.), Jürgen Baltes, Dr. Till Ergenzinger, Dr. Tom Haverkamp Vorsitzender des Aufsichtsrats: Dr. Georg F.
