Span status code not indicating as error in the trace UI

[nextrevision]

What happened:

I'm using the latest version of the OpenTelemetry Clickhouse Exporter and have it integrated with Grafana 10.x using the latest Clickhouse datasource version. I can view the trace, but the error icon/indicator does not appear.

What you expected to happen:

When viewing a trace with spans that are of STATUS_CODE_ERROR, I would expect a visual hint.

How to reproduce it (as minimally and precisely as possible):

I think what is missing is a SpanAttribute named error being explicitly set. Since OpenTelemetry doesn't appear to support error as a SpanAttribute through their SDKs, would it be better to key off of the StatusCode column directly?

Screenshots

Below without the indicator:

A query showing the result:

SELECT StatusCode
FROM otel_traces
WHERE SpanId = 'e13714f30858326c'

Query id: 13342227-f21a-4196-8a1b-d970b7211ce5

   ┌─StatusCode────────┐
1. │ STATUS_CODE_ERROR │
   └───────────────────┘

1 row in set.

Environment:

• Grafana version: 10.4.1
• Plugin version: Clickhouse 4.0.6
• OS Grafana is installed on: Linux/Docker
• User OS & Browser: Firefox

The trace panel requires a specific column name to be returned, usually with a specific data type.

This structure is defined here: https://grafana.com/docs/grafana/latest/explore/trace-integration/#data-api

You can try writing a query that shows the status you want. If you have any suggestions on how to do this consistently from one of the other columns (such as StatusCode or Severity*), let me know and we could look into adding it.

Thanks!

Hi @nextrevision, I'm closing this as based on the comment from @SpencerTorres above this should have a workaround to provide the correct data schema. Please re-open if this is still a problem for you!

I'm not sure this is something that should be solved outside of the plugin, mainly because the plugin requires the opentelemetry clickhouse exporter to function. I am using the exporter with no modifications. I think the since clickhouse datasource plugin requires the otel exporter, it should add support for displaying errors that are builtin to the schema.

I'm sorry, but where is the structure described? How do I know what field names and types the plugin expects for full display?
