Apart from the counters that you can access through dbus, is there any other monitoring built into Ganesha?

I'm thinking of adding it with this higher level plan:

- Exporting metrics from Ganesha to Prometheus.

- Aggregate data in Prometheus.

- Display monitoring consoles and graphs with Grafana.

- Package up Prometheus, Grafana and the preconfigured rules/dashboards as a Docker image.

- This makes it straightforward to deploy monitoring alongside a Gansha binary.

My rough coding plan for the code is to:

- Add a USE_MONITORING directive to the CMakeLists.txt files.

- Add a build dependency to the Prometheus C client.

- Create a src/monitoring directory for the new source files and templates.

- Increment counters and timers throughout the code.

- Use histograms to compute latency percentiles, heatmaps, etc.

Is this a good idea? Any objections or suggestions?

Thanks,

Bjorn
