Hello everyone,
I have a problem with host and service escalations in Nagios 2.0. I have
upgraded to Nagios 2.0 when I tried to use escalations and thought there was
a bug in Nagios 1.2. I'm going to describe the problem:
I'd like to escalate the notifications to send only once an SMS about an
HOST or SERVICE DOWN, but still have the e-mails being sent periodically.
To get things even more complicated I would like that, in some cases, the
SMS to sent only in the nightly hours.
For start I have built a config using only 24x7 time periods. This way I
prepared the following config:
(See the results after this sample config)
-- start of sample config --
# 'sms-host' host group definition
define hostgroup {
hostgroup_name sms-host
alias SMS Hosts
members testhost
}
define host {
host_name testhost
alias testhost
address 1.2.3.4
check_command check-host-alive
active_checks_enabled 1
checks_enabled 1
max_check_attempts 3
check_interval 5
notification_interval 5
contact_groups testhost-email-contacts,testhost-sms-contacts
}
# Send the first notification to the SMS-Contacts (only when DOWN)
define hostescalation {
host_name testhost
contact_groups testhost-sms-contacts
first_notification 1
last_notification 1
notification_interval 5
escalation_period 24x7
escalation_options d
}
# Send notifications to e-mail contacts periodically since the beginning
# of the problem until RECOVERY.
define hostescalation {
host_name testhost
contact_groups testhost-email-contacts
first_notification 1
last_notification 0
notification_interval 5
escalation_period 24x7
escalation_options d,u,r
}
# For the service let's try a different approach
# The first notification will use service default "contact_groups"
define service {
host_name testhost
service_description SSH
check_command check_ssh
max_check_attempts 3
normal_check_interval 5
retry_check_interval 1
check_period 24x7
notification_interval 5
notification_period 24x7
notification_options c,r
contact_groups testhost-email-contacts,testhost-sms-contacts
}
# The rest of notifications send only to email contacts
define serviceescalation {
host_name testhost
service_description SSH
first_notification 2
last_notification 0
notification_interval 5
contact_groups testhost-email-contacts
}
-- end of sample config --
The Results:
For the host config, Nagios doesn't send any notification at all no matter
the host status is (DOWN, UNREACHABLE or RECOVERY)!
For the service config it sends the first notification to both e-mail and
sms contacts and rest of notifications only to e-mail contacts.
The service config approach almost does what I need, but doesn't let change
the timeperiod of the first notification for the sms contacts without
affecting the e-mail contacts too.
Of course the notification intervals are short for test purposes only.
The problem:
Why Nagios doesn't send any notification at all with sample host config?
What am I doing wrong? Is there a global variable config that I have missed
in documentation that could change escalations behaviour?
I have read several times this explanation about escalation and I can't
reproduce the same behaviour the document states:
http://nagios.sourceforge.net/docs/2_0/escalations.html
Thanks in advance for the help!
Best Regards,
Jorge Matias
