Hi ,

I am trying to use metricbeat (version 8.1.2) module for Redis.
Redis cluster is managed app.redislabs.com

Here is the config:

  metricsets: ["info", "keyspace"]
  hosts: ["redis-16058.internal.xxxxxxxxx.ec2.cloud.redislabs.com:16058"]
  password: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
  enabled: true
  period: 10s

Redis hosts

hosts: ["redis-16058.xxxxxxxxx.ec2.cloud.redislabs.com:16058"]

Redis AUTH password. Empty by default.

password: (blank if no auth. Tried with password as well as without)

I am getting below errors in /var/log/metricbeat/metricbeat.log:

{"log.level":"error","@timestamp":"2022-06-03T04:43:29.941Z","log.origin":{"file.name":"metrics/metrics.go","file.line":306},"message":"error determining cgroups version: error reading /proc/89458/cgroup: open /proc/89458/cgroup: no such file or directory","service.name":"metricbeat","ecs.version":"1.6.0"}

Also If i try to connect to my local redis running on localhost I am able to see the metrics.
Using hosts: ["127.0.0.1:6379"]

Any suggestion on what could be the reason?

Thanks!

Anybody has any idea what the issue could be? Am i missing something?
