Problem with High Availability of Redis Sentinel in Windows

[Tarun Khurana]

Hi folks,

I am running into a problem with Sentinel. When I issue the command SENTINEL slaves mymaster it doesn't return anything whereas I have 2 slaves. If I run the info command again after few minutes it displays master0:name=redisvm,status=sdown,address=10.0.17.4:6379,slaves=0,sentinels=1 Can you please offer any ideas.

Sentinel Configuration:

sentinel myid 87a5f828aeb1e2cb5d8b2a4bbf1c5e46da2bca21

# Generated by CONFIG REWRITE

port 26379

dir "C:\\Program Files\\Redis"

sentinel monitor redisvm x.x.x.x 6379 2

sentinel down-after-milliseconds redisvm 60000
