I have setup a few host and HTTP service checks and alerts. When a host goes down I recieve an email, but when the check_http service fails (e.g. the TCP port is shutdown on the web server) I see the service alert in the nagios.log as follows:
[1168038639] EXTERNAL COMMAND: SCHEDULE_FORCED_SVC_CHECK;ebro;Website App Server MS2;1168038636
[1168038644] SERVICE ALERT: ebro;Website App Server MS2;CRITICAL;SOFT;1;Connection refused
[1168038824] SERVICE ALERT: ebro;Website App Server MS2;CRITICAL;SOFT;2;Connection refused
[1168039004] SERVICE ALERT: ebro;Website App Server MS2;CRITICAL;SOFT;3;Connection refused
But I do not recieve an email. The following service is defined:
define service{
host_name ebro
service_description Website App Server MS2
check_command check_http_fitness_app
max_check_attempts 5
normal_check_interval 5
retry_check_interval 3
check_period 24x7
contact_groups jboss-admins
notification_interval 30
notification_period 24x7
notification_options w,u,c,r,f
}
The following contact is setup for the jboss-admins groups:
define contactgroup{
contactgroup_name jboss-admins
alias JBoss Administrators
members wnorth
}
The following contact is setup for wnorth:
define contact{
contact_name wnorth
alias Wes North
service_notification_period 24x7
host_notification_period 24x7
service_notification_options w,u,c,r,f
host_notification_options d,u,r,f
service_notification_commands notify-by-email
host_notification_commands host-notify-by-email
email wnorth at verizon.net
}
If I bring a host offline I see the following alert in the nagios.log:
[1168037707] HOST NOTIFICATION: wnorth;ebro;DOWN;host-notify-by-email;CRITICAL - Host Unreachable (10.0.33.8)
[1168037767] HOST ALERT: ebro;UP;HARD;1;PING OK - Packet loss = 0%, RTA = 0.40 ms
[1168037767] HOST NOTIFICATION: wnorth;ebro;UP;host-notify-by-email;PING OK - Packet loss = 0%, RTA = 0.40 ms
But if I bring a web service offline it fails to email me. I don't know why, I have specified everything correctly. Any insight would be much appreciated.
