Exception Attributes Query in ClickHouse Table

TLDR Vishnu needed help locating exception attributes in ClickHouse table. Srikanth confirmed that the attributes are stored in signoz_index_v2, not the exceptions table, and recommended creating an issue for further development.

Hi,
I want to create dashboard/query for the exceptions recorded grouped by a custom field like userId/tenantId.
While recording the exception in the application, we have the option to pass Attributes with opentelemetry.

 Span.current().recordException(throwable, Attributes.of(AttributeKey.stringKey("userId"), userId));

Can you please let me know which table in clickhouse will store this attribute or query to achieve the above. I checked in signoz_traces.signoz_error_index_v2 table.
Also please share if there is any documentation on the database schema for clickhouse.

You are looking at the right table

Srikanth Not able to find that field in this table, can you please let me know the column. There is a column of resourceTagsMap but that dosen't contain this

I just realised we are not storing all the exception attributes. This needs some development work. Would you mind opening an issue?

Srikanth Sure will do that, but i can see the attribute on the event tab of the trace where the exception is recorded. But could not find in the table that i mentioned above.

Srikanth I can see the new attributes on the ui, not sure which table this is being stored.

They are not part of the exceptions table. They are part of the signoz_index_v2 which has stringified event json.

Understood. These should be present in the error index as well. Should i create a issue?
