Golerta

A simplified reimplementation of alerta in golang.

Rethinkdb is used instead of Mongodb for operational simplicity and real-time data features.

features

• All-in-one server - static content, api, and continuous queries
• LDAP Authentication
• OAuth Authenticaion
• Alert routing via plugins - current plugins: file, pagerduty
• Optional alert time outs - if an alert has a timeout field it will escalate to critical if a new alert isn't received within a given amount of time
• Timed acknowledgements - alerts will reopen after a specified amount of time
• Flap detection - alerts that continually change severity state will be marked as flapping
• Select and update alerts from the list view
• IN DEVELOPMENT: Web sockets on the client side - web browser no longer polls and new alerts are received immediately
• IN DEVELOPMENT: Fully distributed - Currently the continuous queries can only be run on a single node without duplicating effort.
