Redis transport duplicate checks

[sstarcher]

Servers are running checks five times. I have dropped the redis cache and restart all of the sensu clients and server.

Sensu 0.24.1

• transport - redis
• client - no checks locally
• server - checks loaded, seperate server from api, single server
• api - checks loaded, seperate server from api, single api

@sstarcher what version of Redis are you using? What does your Redis deployment look like?

[sstarcher]

@portertech This is an AWS elasticache redis instance

Engine: 2.8.24

I'm using the AWS defaults for 2.8. I can get a list of them if you want.

[portertech]

We need to investigate TCP connection error/failure vs Redis error and the difference in handling.

Sensu 0.27 will have several sensu-transport Redis improvements and fixes, the release is expected to drop in the next 2 weeks. We are still able to reproduce duplicate check results when triggering an Elasticache HA failover 👎

@portertech Any updates on using redis as a transport for Sensu core 1.5/1.6 ?
