we have master redis and 17 slaves running on k8s pods, and some of slave may share same redis host IP, this is used in production environment.

and when use redis exporter to collect metrics to prometheus side, exporter will report error as connected_slaves has duplicated data.

Googling showed that redis metric with "alias" label, but i'm not sure if its possible to add alias for dup redis slaves, thanks for help.

# Replication
role:master
connected_slaves:17
slave0:ip=1.2.3.4,port=6380,state=online,offset=248362542645,lag=0
slave1:ip=1.2.3.4,port=6380,state=online,offset=248362542645,lag=0

.....

# TYPE redis_connected_slave_offset gauge
redis_connected_slave_offset{addr="localhost:7000",alias="",slave_ip="127.0.0.1",slave_state="online"} 113638
redis_connected_slave_offset{addr="localhost:7001",alias="",slave_ip="127.0.0.1",slave_state="online"} 186453
redis_connected_slave_offset{addr="localhost:7002",alias="",slave_ip="127.0.0.1",slave_state="online"} 186396
