Re: Unable to analyse thread level information in MySQL server

[Rick James]

Please elaborate on what you hope to learn -- at a higher level.

See "Performance Schema" for detailed timings (but not at the OS thread level).

Here are some general statements about thread usage. Here, I refer to MySQL threads; I don't know if they map to OS threads, or whether they wander around.
* Each connection directly uses only one thread.
* InnoDB has several background threads to handle I/O, etc.
