+1 for Grafana together with Loki and Prometheus. This saved us so much trouble. We thought about using DD first but the costs were so intransparent.

Grafana Tempo for the traces looks interesting too! Especially now that it doesn't require Elastic anymore

Curious, do you use self-host Prom+Loki?

I do it with my clients, but we're not using a lot of clusters.

Grafana, for long, has been used to monitor time-series data and recently has been moving towards observability (including traces and logs). We are different in quite a few fronts.

1. There are specific observabilty specific UI widgets like serviceMap, SLOs and error budgets, I don't know whether Grafana provides it now. Also, last I used Grafana, linking and moving from one dashboard to another is still a pain. You can get a better idea of how different observability UI can get from Grafana by looking into LightStep demo.

2. We can run aggregated on filtered traces. Eg, I can get 99th percentile response time of a tag say payment_channel. am afraid this can be extracted from traces by Grafana.

3. SigNoz is easily extendible by adding your stream processing application to slice n dice data in your own way
