I'm a single person working on a real-time data hobby project in Scala. The rough of the app is:<p>- subscribes to a bunch of feeds over websockets<p>- aggregates the messages somewhat<p>- passes them through some ML models and decision makers which are organised hierarchically<p>- executes the decisions<p>- listens on feeds that relay decision updates<p>A lot of it is CRUD and a lot of it is actors passing messages around. I'm getting to the point where I don't want to be scanning through log lines anymore and need to set up some visibility but time is scarce so want to ask around:<p>What is there apart from Kibana?<p>Kibana is a pretty good fit, there's a Scala library that extracts structured logs from string interpolations (https://izumi.7mind.io/logstage) so before long I could have a very searchable log and all kinds of dashboards.<p>The one nice-to-have that I'd miss is capturing my hierarchies. It'd be more helpful if I could also have a network view of all my entities, their nestings and the throughput between them. That'd be really nice but again, it's a nice to have and I'd like it to be very low setup<p>Am I missing something obvious? Grafana?
