Sentry solves tangential but different use cases. E.g does not allow you to define custom metrics to e.g. monitor resource utilization

I think that might not quite be the case in the latest versions: https://docs.sentry.io/product/performance/metrics/#custom-p...

  In addition to the automatic performance metrics described above, Sentry supports setting custom performance metrics on transactions. 
  Custom performance metrics allow you to define metrics (beyond the ones mentioned above) that are important to your application and send them to Sentry.
  For example, you might want to set a custom metric to track:
  - Total memory usage during a transaction
  - The amount of time being queried
  - Number of times a user performed an action during a transaction
  You define and configure custom metrics in the SDK.

Though for my use cases, Sentry's technical complexity is more of a stumbling block, were I to self-host it: https://github.com/getsentry/self-hosted/blob/master/docker-...
