Nagios not sending alerts

[Allanm]

Nagios is sparingly sending alerts, not sure where the problem is, here is what I have done -

1) created generic contact template and contact (in contacts.cfg) called nagios which is also a local user on the box.

define contact{
name generic-contact ; The name of this contact template
service_notification_period 24x7 ; service notifications can be sent anytime
host_notification_period 24x7 ; host notifications can be sent anytime
service_notification_options w,u,c,r,f,s ; send notifications for all service states, flapping events, and scheduled downtime events
host_notification_options d,u,r,f,s ; send notifications for all host states, flapping events, and scheduled downtime events
service_notification_commands notify-service-by-email ; send service notifications via email
host_notification_commands notify-host-by-email ; send host notifications via email
register 0 ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL CONTACT, JUST A TEMPLATE!
}

define contact{
contact_name nagios ; Short name of user
use generic-contact ; Inherit default values from generic-contact template (defined above)
alias Nagios Admin ; Full name of user
service_notification_period 24x7
host_notification_period 24x7
service_notification_options u,c
host_notification_options n
service_notification_commands notify-by-email
host_notification_commands notify-host-by-email
email nagios@localhost ; <<***** CHANGE THIS TO YOUR EMAIL ADDRESS ******
}

2) within contacts.cfg made it part of admin group -

define contactgroup{
contactgroup_name admins
alias Nagios Administrators
members nagios
}

3) In commands.cfg, created a command to send an alert thru email -

define command{
command_name notify-by-email
command_line /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$" | /usr/bin/mail -s "** $NOTIFICATIONTYPE$ alert - $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$
}

4) In services.cfg added admins group for notification for each of the service defined -

contact_groups admins

5) added a couple of email ids in /etc/aliases -

nagios tom@xxx.com, harry@xxx.com

6) ran newaliases and nagios process using -v and -d switches and it ran just fine.

Sending alert from the commandline also works.Even I got a few email alerts but not consistently.Location of mail is same as defined above in commands,cfg.

Please help!

Thanks,
Allan
