I was looking into this just yesterday. So the Loki + … comparison is a bit off in the Open Source space. The main ones are Signoz and ClickStack in this space. Both using ClickHouse as the database. Heavy compared to something like Loki, but they are OTEL native and not log monitoring. So not in the same category.
I used Signoz + Clickstack on a vibe coded Go server project a few weeks ago. I just made codex figure out how to setup signoz + dependencies via docker compose. I even got it to pre-populate signoz with dashboards. It wasn't too bad. The whole thing runs with a few GB. I tried to cover metrics, tracing, and logging at the same time. This is not a production ready setup but you need to trade off cost vs. utility here. If it's useful enough, that could justify extra cost.
I have a background in having done a lot of stuff on the Elastic stack related to this; including setting up a big Elastic Fleet based stack for one client at some point. It might not be the cheapest, but it does provide awesome filtering and querying capabilities. However, a lot of teams that use it don't really know how to tap into that capability so it tends to be overengineered for what it does in the end. And the extra, underutilized complexity is why a lot of teams are wary of dealing with that stack.
Storing the data is the easy part but what's the point if you can't run queries against it and produce dashboards and diagnostic tools that actually help you? Prometheus/grafana or older graphite type setups tend to be compromises where you get lots of data but are then limited on the querying front or the number of metrics. The tradeoff is always between scale and querying flexibility. If you store tens/hundreds of GB of telemetry per day, you need a way to make sense of it. Clickhouse seems to be quite good at scaling and querying. It's basically a column database. I don't have direct experience with Loki.
But in the end, all that power only matters if people actually use it. And, again, in my experience teams tend not to. They tend to have a lot of unrealized aspirations around their tools and infrastructure. If it's just a dumping ground for data + a few simplistic dashboards, optimize for that. A lot of that data is actually only kept for compliance/auditing reasons. For that, querying is usually a secondary concern and it's OK if queries take a bit longer and are less powerful.
- ClickStack (ex HyperDX) - SigNoz - Traceway - a few more
does someone has enough feedback on those to be able to tell which one works best?

But you can't beat the excellent price and performance. Does what I need and much more
