Redis Monitoring

For Redis montioring we need to run an exporter to scrape the metrics from Redis and following is the command to pull the docker image and to run it:

docker pull oliver006/redis_exporter
docker run -d --name redis_exporter -p 9121:9121 oliver006/redis_exporter -redis.addr "redis://172.31.14.232:6379" -redis.password "password"

Please provide the password which is set for redis auth, along with -redis.password parameter.

Once redis-exporter docker service is running, user can get the metrics from

curl http://127.0.0.1:9121/metrics

9121 being the default port of exporter

Once we get the metrics, add /etc/prometheus/prometheus.yml following in prometheus.yml and restart the prometheus docker container:

- job_name: 'redis'
metrics_path: '/metrics'
scrape_interval: 5s
static_configs:
- targets: ['172.31.36.120:9121']

Login to Grafana and import custom dashboard (Redis.json) for Redis.
