Redis exporter doesn't expose redis-cli info to prometheus metrics about redis_exporter HOT 10 CLOSED

That's trying to connect to localhost but from within the context to your container, that shouldn't be valid. Try passing the actual address of the redis container (in my docker-compose example that's redis://redis-server:6379).

from redis_exporter.

Same for me, I couldn't find any solution, to receive specific keys here.. Had you already success?

In my case, only some info e.g. redis_up is available.. not more..

redis_up{addr="prod.redis",endpoint="http-metrics",instance="172.31.19.191:9121",job="redis-exporter",namespace="monitoring",pod="redis-exporter-2724175770-gtzsg",service="redis-exporter"}

from redis_exporter.

no it's not working for me ,im using this grafana templates https://github.com/oliver006/redis_exporter/tree/master/contrib
and it's failed to pull all the metrics from the template

from redis_exporter.

Using this minimal docker-compose file:

version: '2'

services:
  redis-server:
    image: redis:3.2.10
    ports:
      - 6379:6379

  redis-exporter:
    image: oliver006/redis_exporter:v0.11.3
    ports:
      - 9121:9121
    entrypoint: /bin/redis_exporter -redis.addr redis://redis-server:6379

First, docker-compose up

If you now run curl -s localhost:9121/metrics | grep redis_

I see all the redis_ metrics as expected.

How are you running / configuring the redis_exporter ?

from redis_exporter.

hi
im running this command
docker run -d --name redis_exporter -p 9121:9121 oliver006/redis_exporter -redis.addr redis://localhost:6379 -redis.password 'haha'

my redis server is running as a service and not as docker command

and i got only this metrics

from redis_exporter.

now it's working you are right the problem was with the localhost

from redis_exporter.

thanks a lot

from redis_exporter.

Good to hear it's working now!

from redis_exporter.

I found out, that in my case problems with DNS caused the problem.. The telnet prod.redis 6379 works..

that did not work
REDIS_ADDR=tcp://prod.redis:6379 /bin/redis_exporter -web.listen-address :9122 -check-keys connected_clients

error message:
INFO[0173] redis err: dial tcp: lookup prod.redis on 172.31.0.2:53: no such host

using the IP directly works..
REDIS_ADDR=tcp://10.100.123.75:6379 /bin/redis_exporter -web.listen-address :9122 -check-keys connected_clients

from redis_exporter.

In my case, redis was configured to open only local connections. Then updated bind parameter in /etc/redis/redis/conf to accept external connection and restarted redis service. It resolved.
