Introduce a tracectl tool
rburchell opened this issue · comments
To control traced without restarting it.
For instance:
- tracectl start -- I want to see what's going on, please start dumping to a file
- tracectl stop -- I don't care now. Stop dumping and clear buffers if any.
- tracectl restart -- obvious
Other possibilities, who knows... "show me only PIDs X, Y, Z, thread IDs A, B, C"... but that can come later.
