I don't think this can be done with escalations. If Assaf has a way to do it,
I'd be very interested. Like the documentation says, any notification that
matches multiple escalations can only have one notification interval and it
chooses the smallest. The way we get around the problem is to put a wrapper
around the email notification command so that it only sends the first
notification of a state change. This is what it looks like:
define command{
command_namenotify-host-by-email
command_line\
if [ $HOSTNOTIFICATIONNUMBER$ -le 1 -o $HOSTSTATEID$ -ne
$LASTHOSTSTATEID$ ]$USER9$ then \
/usr/bin/printf "%b\n\n--" \
"* Nagios *\n\n\
Notification Type: $NOTIFICATIONTYPE$ Number: $HOSTNOTIFICATIONNUMBER$\n\n\
host=$HOSTNAME$\n\n\
Host: $HOSTNAME$\n\
Address: $HOSTADDRESS$\n\
State: $HOSTSTATE$\n\
Last State: $LASTHOSTSTATE$\n\
Info: $HOSTOUTPUT$\n\n\
$LONGHOSTOUTPUT$\n\n\
Date/Time: $LONGDATETIME$\n\n\
Comment: $NOTIFICATIONCOMMENT$" \
| /usr/bin/mail -r nagios -s \
"** Nagios $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is
$HOSTSTATE$ **" $CONTACTEMAIL$ \
$USER9$\
fi
}
The $USER9$ macro is defined as a semicolon ';' to keep it from being
interpreted as the start of a comment. The command for service e-mail
notifications looks similar. So, for e-mail notifications, it doesn't matter
what the interval is. Only one e-mail will actually be sent per state change.

Re: [Nagios-users] different escalation intervals possible?
Thanks Assaf. It's a little complicated, but here's my config for a 'critical
service':
### First my escalation definitions:
define serviceescalation {
namepage-primary
first_notification 1
last_notification 0
notification_interval 15
contact_groups primarypager
servicegroup_name critical-services
}
define serviceescalation {
namepage-secondary
first_notification 3
last_notification 0
notification_interval 15
contact_groups secondarypager
servicegroup_name critical-services
}
define serviceescalation {
nameemail-ops
first_notification 1
last_notification 0
notification_interval 120
contact_groups ops-group
servicegroup_name critical-services
}
Now my contact groups
define contactgroup {
contactgroup_name ops-group
alias Operations People
}
define contactgroup {
contactgroup_name primarypager
alias Primary Pager
}
define contactgroup {
contactgroup_name secondarypager
alias Secondary Pager
}
Now a pair of example contacts (and templates) that tie into those groups
define contact {
namegeneric-contact
host_notification_period24x7
service_notification_period 24x7
host_notifications_enabled 0
host_notification_options d,u,r
service_notification_optionsu,c,w,r
host_notification_commands host-notify-by-email
service_notification_commands service-notify-by-email
register0
can_submit_commands 1
}
# pager template
define contact {
namepager-template
use generic-contact
host_notification_options d,u
service_notification_optionsu,c
host_notification_commands host-notify-by-epager
service_notification_commands service-notify-by-epager
register0
}
define contact {
nameops-contact
contactgroups ops-group
use generic-contact
register0
}
define contact {
contact_namemb
alias Michael Barrett
use ops-contact
email lok...@gmail.com
}
define contact {
contact_namemb-phone
alias Mike Phone
contactgroups primarypager
use pager-template
email @mms.att.net
}
Now the servicegroup for critical-services
define servicegroup {
servicegroup_name critical-services
alias Services that should page
}
And finally a service that is in critical services (and its template)
define service {
namegeneric-service
is_volatile 0
check_period24x7
max_check_attempts 3
normal_check_interval 5
retry_check_interval1
active_checks_enabled 1
passive_checks_enabled 1
parallelize_check 0
obsess_over_service 1
check_freshness 0
notifications_enabled 1
notification_interval 120
notification_period 24x7
notification_optionsu,c,w,r
event_handler_enabled 1
flap_detection_enabled 1
process_perf_data 1
retain_status_information 1
retain_nonstatus_information1
contact_groups ops-group
register0
}
define service {
use generic-service
service_description puppet last run
check_command check_puppet
hostgroup_name all_hosts,!virtual-hosts
servicegroups critical-services
}
##
Let me know if you have any questions, and thanks again!

[Nagios-users] different escalation intervals possible?
Hi - I am trying to get alerts for my services to work like this: - all alerts (warning, critical, unknown, and recovery) go to the 'email-ops' contact every 2 hours - on some services (the ones deemed critical) in addition I want them to send an email to the 'primary-pager' contact every 15 minutes I thought I had the configuration setup appropriately for this, but now I'm not sure it's possible without a better understanding of how escalations work (and it may not even be possible then) since I read this about overlapping escalations: "Since it is possible to have overlapping escalation definitions for a particular hostgroup or service, and the fact that a host can be a member of multiple hostgroups, Nagios has to make a decision on what to do as far as the notification interval is concerned when escalation definitions overlap. In any case where there are multiple valid escalation definitions for a particular notification, Nagios will choose the smallest notification interval." Anyway, is there anyway to make that work? The way its working now is that it seems to email the email-ops list every 15 minutes on critical services, and for email we'd like to get less alerts.
