Summary

We have basic usage docs for loki, but we are lacking usecase documentation. Some things that initially come to mind:

How do I...

• Check logs for my deployed apps?
• Check logs for my jupyter server?
• Check logs for conda-store (server/worker)?
• See how many people are on the platform?
• Check memory usage of my server?

Steps to Resolve this Issue

These docs need to be expanded: https://www.nebari.dev/docs/how-tos/monitoring#loki

No problem, we can just focus on what is available right now.
