Ciclope
Simple utility to show the replication status for MySQL hots. Usefull to inspect seconds behind master status.
NOTE: This gem depends on Rails and ActiveRecord as ORM.
Configuration
Only has to specify a array of two or more Rails database config names:
Ciclope.connections = [:production, :production_in_aws, :production_in_other_location]
The ring will be auto-sorted guessing the master host for each connection, you could bypass this feature setting:
Ciclope.auto_sort_connections = false
Use
Actually there is one class methods to inspect replication data and one to show seconds behind master:
Ciclope.replication_status # => returns a array of hashes with replication data
Ciclope.replication_seconds_behind_master # => returns a simple string with the host status like:
host1 ––– 0 seconds –––> host2 ––– 0 seconds –––> host3 ––– 0 seconds –––> host1
TODO
Extend and refact in order to let work with others frameworks ruby based (Sinatra, Merb), and others ORMs (DataMapper).
