Redis : Failed to fetch redis info for keyspaces: read tcp xxx->xxx i/o timeout

[masyutka]

Hi ,

I am trying to use metricbeat (version 7.12.1) module for Redis.
Redis cluster is managed AWS ElastiCache.

Here is config:

• module: redis
  metricsets: ["info", "keyspace"]
  enabled: true
  period: 2m

  Redis hosts

  hosts: ["clustercfg.sandboxXXXXXX.amazonaws.com:6379"]

  Redis AUTH password. Empty by default.

  password: ${redispwd}

I am getting below errors:
2022-03-09T03:06:12.709Z ERROR redis/redis.go:70 Error retrieving INFO stats: read tcp 192.168.59.219:39884->192.168.168.181:6379: i/o timeout

However I can telnet from node where metricbeat is running to Redis clustercfg.sandboxXXXXXX.amazonaws.com 6379.

Any suggestion on what could be the reason?

Thanks!

Hi @masyutka!

when you tried to telnet was clustercfg.sandboxXXXXXX.amazonaws.com resolved to the same IP as in error logs - 192.168.168.181?
did you try to telnet directly to IP?

IP 192.168.59.219 is it IP of the node, where you tried to telnet from?
