questions regarding a few metrics (Active Request/Datasource).

[jaca-p]

I have questions regarding the Active Request and Datasource metrics.

We are currently using version 2.3.3 of the web/collector/agent.
The Datasource metrics are intermittently displayed per service.
I've checked issue #4602 regarding the Datasource.
Are DBCP1, DBCP2, and HikariCP the only ones supported currently?

Additionally, Active Request metrics are mostly not measured correctly (showing as 0),
and the Application Inspector shows Active Request as "No data."
I've reviewed issue #9908, but the communication between the collector and web is functioning normally.
When sending Active Request data from the Agent to the collector, does it use a specific port?
Also, could you explain how Active Requests are measured?

I checked and found that only ports 9991-9994 are open for the agent, while ports 9995 and 9996 are closed.
Could this be the main cause? What is the difference between data that communicates over UDP and data that communicates over TCP?
