What about adding a debug api, just as what tidb does. ref: https://github.com/pingcap/tidb/blob/master/docs/tidb_http_api.md

Download TiDB debug info

curl http://{TiDBIP}:10080/debug/zip?seconds=60 --output debug.zip
zip file will include:

Go heap pprof(after GC)
Go cpu pprof(10s)
Go mutex pprof
Full goroutine
TiDB config and version
Param:

seconds: profile time(s), default is 10s.

However, the shell script is also needed for the old cdc version users.
