Are there any guides?
have you looked at this?
and
Thank you for your reply, i hava looked both at them, only 2 sql on the picture look useful in this situation, and i even dont know what kind of grafana panel suits for these sql.
There are 5 kinds of metric table that otelcol creates, and I am not sure how to effectively display these metric data in Grafana in detail to maximize their value.
What’s more, I know how to link logs and traces in Grafana, for example, the latest ClickHouse datasource allows jumping between fields. However, I can’t find any solutions or guides on how to link metrics with logs or traces.
start one table at a time. what visualization do you want to use for the first table? what are the columns in the first?
I’m facing a similar problem as @wudadada.
I’m considering using Clickhouse as the backend for a Device Observability platform with Otel, I’m still in the validation phase. However, I can’t seem to find en example of how to display data stored in otel_histogram or otel_exponential_histogram tables.
All I could find was this thread, but the proposed solutions there are quite cumbersome. I can imagine that having Clickhouse designed the destination tables, there should be a simple example of how to consume these data.
Also, by default sums are stored using cumulative aggregation temporality. While I understand the benefits of this while transmitting data (in case of data loss, it’s easy to interpolate missing values) but is it a good option to store sums as a cumulative metric?
