I just launched redis_failover 1.0. It now supports distributed monitoring among the Node Managers! Previously, the Node Managers were only used as a means of redundancy in case a particular node manager crashed. Starting with version 1.0 of redis_failover, the Node Managers will all periodically report their health report/snapshots. The primary Node Manager will utilize a configurable “node strategy” to determine if a particular node is available or unavailable.

redis_failover now supports a configurable “failover strategy” that’s consulted when performing a failover. Currently, a single strategy is provided that takes into account the average latency of the last health check to the redis server.
