Question: I am trying to clear all the stale old renamed clients from my `uchiwa` dashboard. I am unable to clear them. 

Basically I renamed the clients with a new name, but the old clients keep showing up on the dashboard.

I restarted `sensu-server`, `uchiwa` dashboard, and `redis-server`. Still I keep seeing the stale entries.

Answer: 
I had to get into `redis-cli` prompt, and run `flushall`. This cleared all the old events. Ideally redis-server restart should have cleared it. Well, now its all neat.

I also restarted rabbitmq-server.
In Uchiwa, under clients, you can select a client and delete it. The client will then disapear.
