I have a Nagios server which monitors many servers. There's a dashboard which has been coded in-house and it sends monitoring data using passive checks to the Nagios server. Whenever an issue occurs, the NOC team is being flooded with email notifications.
My aim is:
When an issue occurs, and even if the dashboard sends 100 notification emails to Nagios, I want Nagios to aggregate the notifications into one notification. Then I expect Nagios to send one more notification when the issue is resolved. How is it done?
Flapjack is designed to help with this.
I'm pretty sure that Etsy's Nagios Herald address this issue.I'm told that what you want instead is the check_check.rb within the ruby-nagios gem. (H/T Ryan Franz)
