Change into the observability-stats directory.

In a terminal run this command to get a shell prompt inside the running Docker container:

A simple way to to generate some load is to open another terminal and run:

Since most of the stats data comes from the INFO command you should first run this to view that there.

Try piping this output to a file.

Since we generally recommend setting the maxmemory size, it is possible to calculate the percentage of memory in use and alert based on results of the maxmemory configuration value and the used_memory stat.

First set the maxmemory.

Then you can pull the two data points to see how that could be used to calculate memory usage.

You can pull the clients section of the INFO command

or maybe a particular metric you would want to track:

Use redis-cli to list the full 'stats' section.

A cache hit/miss ratio could be generated using two data points in the stats section.

Eviction occurs when Redis has reached its maximum memory and maxmemory-policy in redis.conf is set to something other than volatile-lru.

The following data could be used for graphing the size of the keyspace as a quick drop or spike in the number of keys is a good indicator of issues.

The following stats are a good indicator of workload on the Redis server.
