@vitalygorohovik93 would this be based on the redis RESP protocol that garnet exposes or something specific to garnet? meaning - is there some existing docker image we could simply add as a another container or do we need to create something new?

Grafana/Prometheus integration probably requires #379

We can use Grafana OSS with the Redis plugin, which comes with a built-in dashboard. The problem is that some panels don't show data, as comments (like COMMANDSTATS, SLOWLOG) are not yet supported. Other panels worked as expected when I tested them locally with Garnet. @PaulusParssinen, we don't need OpenTelemetry; this works with the RESP protocol. Still better to have OpenTelemetry as well.
