with redis auth and --is-cluster "NOPERM this user has no permissions to run the 'cluster' command or its subcommand"

acl user rights: +client +ping +info +config|get +cluster|info +slowlog +latency +memory +select +get +scan +xinfo +type +pfcount +strlen +llen +scard +zcard +hlen +xlen +eval allkeys

I am able to run cluster info from redis-cli authorized with that user In the log i see redis_exporter[11745]: time="2023-04-12T13:26:41+03:00" level=error msg="Cluster refresh failed: redisc: all nodes failed\nNOPERM this user has no permissions to run the 'cluster' command or its subcommand" If I do "acl setuser +cluster", message dissapear, if do again "acl setuser -cluster +cluster|info" message appears again. Without --is-cluster flag there is no such message in the log.

ACL LOG doesn't contain anything about this, also i see in the code if "CLUSTER", "INFO" is failed will be other log message.

Ah, interesting. How do you run the exporter? What's the full cmd line? (strip passwords or other sensitive information)

[gzivdo]

/etc/default/redis_exporter: REDIS_EXPORTER_OPTS="--is-cluster --check-streams=somestream1,... systemd service with Environment=REDIS_USER=redis-exporter Environment=REDIS_PASSWORD=somepw EnvironmentFile=-/etc/default/redis_exporter ExecStart=/usr/bin/redis_exporter $REDIS_EXPORTER_OPTS

And the rights are correctly set for the user "redis-exporter" ? (Not obvious from your original post as I don't think that includes the user name)

Somehow it doing cluster slots, but in the code i see cluser info only I think it do go redis lib, we need adjust rights and just add +cluster|slots
