I have installed Nagios 2.10 in RedHat 5, all works fine. Nagios checks all things that I need it.
But passive check, that I use to monitoring host with snmp, dont send me alerts mails.
I have checked the configuration of services and host, and the notifications are enabled.
The notifications for active checks works fine.
In the logfile when an alert appear, I can see this:
[28-02-2008 15:52:50] SERVICE NOTIFICATION: admin_mail;3GServer;3GB02 HTTP;CRITICAL;notify-by-mail;Conexin rehusada
