[Reproduction Path] What operations were performed when the problem occurred
[Encountered Problem: Problem Phenomenon and Impact]
I am debugging the source code. After starting the service with the debug button in Goland on a MAC machine, how can I access the Dashboard locally? I checked the startup log and did not see the http service related to the Dashboard being started.

[Attachment: Screenshot/Log/Monitoring]

Below is the startup log:

The dashboard is integrated into PD, so you need to debug the PD source code.

Thank you for the reply. However, after downloading the source code of TiDB, when debugging, I start with the main() function in tidb-server/main.go. How do I debug PD? Which function should I set as the startup function?

PD is a separate repository, the source code is here:

Thank you for the reply. So, TiDB and PD each have their own separate repositories. If I want to debug the PD source code, how do I combine their source codes for debugging? For example, if I want to debug both TiDB and PD source codes, do I need to start TiDB first through the IDE, then download the PD source code, and then start PD through the debug button in the IDE to debug the PD source code? This way, both TiDB and PD source codes can be debugged?

Yes, you can think of them as two separate projects.

How are TiDB and PD associated? I don’t seem to see a configuration file that links the two. I only saw the configuration linking TiKV and PD.
