Redis Monitor Prometheus

Executes the redis-cli monitor, parse the query and export as a prometheus metrics on port 8080.

The metrics will look like this:

# HELP redis_processed_queries_total The total number of processed events
# TYPE redis_processed_queries_total counter
redis_processed_queries_total 13
# HELP redis_query_executed Total number that a query was executed
# TYPE redis_query_executed counter
redis_query_executed{query="hgetall my_executed_keys"} 13

Environment

* PORT=8080 // Webserver port
* REDIS_URI=redis://your-redis-server-uri:6379;redis://your-redis-server2-uri:6379 // It's also supported multiple servers
* GRANULARITY=1 // Check the section about granularity below

Granularity

It's how many parts of the executed commands do you want.

E.g: The command sismember firstpart secondpart

GRANULARITY = 0 = sismember firstpart secondpart // The whole command
GRANULARITY = 1 = sismember 
GRANULARITY = 2 = sismember firstpart
GRANULARITY = 3 = sismember firstpart secondpart

How to run it with docker (easiest way)

The image is a linux:alpine with redis-cli and the build binary installed. It's only 16.8MB 😄

$ docker run -e PORT=8080 \
    -e REDIS_URI=redis://your-redis-server-uri:6379 \
    -p 8080:8080 \
    herlon214/redis-monitor-prometheus

You can check the docker-compose.yml file, it's a working example.

How to run it without docker

Environment:

• REDIS_URI=redis://your-redis-server-uri:6379

You need the redis-cli installed on your machine.
