Qryn is dropping my tracing information which was generated by opentelementry

[yatamraghu7]

Hi All,

I can see that qryn is dropping the tracing information like traceId, spanId which was generated for my request flow and I cannot find these information in qryn dashboard. I am using Http line instead of grpc and below are the screenshots.

My spring Boot Logs:

My Qryn Dashboard:

It would be great if someone can look into our code here

It's very unlikely for qryn to drop something. Are you sure you set the right labels for the fields?

Please try checking for the raw data inside the qryn database. Like:

SELECT * FROM samples_v3 
WHERE string LIKE '%dd2355bd377%' AND timestamp_ns >= <TIMESTAMP FOR 2024-09-16 17:09:41 IN THE TIMEZONE OF YOUR SCREENSHOT>

And check the result.

Hi @akvlad

I can see that in my logs that was produced in console contains the traceId and spanId and when it comes to qryn I cannot see that. Below are the screenshots

I tried the command that was provided earlier and no luck. Can you help me in understanding where my tracing information was lost.

Thanks

@yatamraghu7 you need to run this in clickhouse, not qryn

SELECT * FROM qryn.samples_v3 
WHERE string LIKE '%dd2355bd377%' AND timestamp_ns >= <TIMESTAMP FOR 2024-09-16 17:09:41 IN THE TIMEZONE OF YOUR SCREENSHOT>

Hi @lmangani

I did ran the provided command inside the clickhouse only and not able to get any results

Thanks

@yatamraghu7 you can't just run SQL in bash! You need to use a clickhouse-client or CLI to query the database: https://clickhouse.com/docs/en/interfaces/cli

Alternatively you can open port 8123 on the clickhouse-server container and use the ClickHouse PLAY UI to run the query

Hi @lmangani

Thanks for pointing out the mistake that I was doing and now I have connected to clickhouse and ran the query got below error.

Can you please suggest how can I move further.

Thanks

Hi @lmangani

Thanks a lot for the support. I am now able to find the issue that when we are exporting the logs from our spring boot to opentelemetry collector which is running on 4318 port it is dropping our tracing information. So I will check with opentelemetry team.

Thanks
