Redis Sentinel output in conf file

Question

I was testing Redis Sentinel's failover ability. It worked, and Sentinel added some lines to the conf files. It auto-discovered the other sentinels and slave replicas, but it added some weird ids.

Can anyone tell me what those ids represent? Since they come right after known-sentinel, I assume they are the id of those sentinels but I can't be sure.

# Generated by CONFIG REWRITE
sentinel known-slave redis_master 127.0.0.1 6379
sentinel known-slave redis_master 127.0.0.1 6381
sentinel known-sentinel redis_master 127.0.0.1 26380

It's the run_id of sentinel. Remember sentinel is a special redis instance. Log into the sentinel and using "info server" to see its information, which includes the run_id. e.g.

redis-cli -h sentinel_host -p sentinel_port
info server

If you have multiple sentinels, you can use

sentinel sentinels mymaster(or redis_master in your situation)

to list all other sentinels' infomation.
