Re: [Nagios-users] single email alert to multiple contacts?
Agree totally! All alerts from Nagios go to the same post-processing script we built and that's where they get shuffled off where they need to go, based on user preferences. We built a database and simple CGI interface (within Nagios pages). Users click on the preferences link and subscribe to systems they are interested in receiving alerts from. They can then decide what email address to send to, based on time of day, hostname, alert level, etc. That takes virtually all the alert management off the Nagios maintainer (me!) and allows people to modify their own contact information (e.g. at work, send to instant messenger. on vacation, send to phone. At home, send to home email. etc) There are fall through rules that can optionally send to an admin group mailbox (with appropriate verbiage in the alert message indicating the fall through) if no one is subscribed to get the alert. Finally, we built a quick dirty reporting page that lists all contacts for all services for all hosts, so we can glance through and pin down gaps. -Original Message- From: Herb J.

Issues like this is just one of the reasons why we had to abstract out all notifications from Nagios to an external script.

[Nagios-users] single email alert to multiple contacts?
Does anyone know how (or if it is even possible) to configure nagios to send a single email to all contacts associated with the host/service/etc as opposed to a separate email to each contact? The problem I'm facing is with emailing distribution lists. If both distribution_list_A and B contain user_A, said user ends up getting 2 email for the same event. If nagios could be configured to send a single email to both distribution lists, our exchange server would recognize that user_A is a member of both lists and send only 1 email to him.
