Redis Slave Connectivity Control

Merhaba! I wrote a plugin using the python to monitor a slave redis to get it really working properly which have replicated master.The reason that i was having replication trouble seeing due to some occurred issues.Sometimes, we couldn’t identify, and tracking this problem between master and slave redis, even we were monitoring many metrics of redis which was running on our monitoring systems.Thus this problem is very important that we capture it. Because we’re using much more redis to keep some specified data in memory of production application which have several structures.Whenever, i pushed this plugin to github for everyone after i started using it.
It is basic to use, and can be lifesaving.
