Performance analysis considerations
In agri, vs-renderer is sometimes overloaded and it's not always easy to find out what is happening in the system.
- enable prometheus metrics (there should be support in eoxserver already)
- build grafana dashboard with interesting metrics
- request ids, also as correlation id for requests from other services or frontends
- add metrics and/or logging on where time is spent, e.g. IO vs DB or mapserver call
what else could be helpful?
