Metric http_server_duration_count always 1 after upgrading agent from 1.24.0 to 1.33.4

[fyuan1316]

Hi team:

After upgrading Otel Java Instrument Agent from version 1.24 to 1.33.4, the http_server_duration_count metric always shows a value of 1.

I suspect that there might be some configuration changes that need to be made along with the upgrade from Otel Java Instrument Agent 1.24.0 to 1.33.4?

I would like to ask:

• Are there any known configuration changes required alongside the upgrade to ensure proper metric collection?
• Could there be any specific settings or parameters that need to be adjusted for version 1.33.4?

Thank you for your assistance!

After some investigation, I discovered that the newly introduced label likely caused the metric to split into multiple different series. I'm closing this discussion.
