mftrace.pthread_ids

Specifies whether CTF evaluates the $(THREAD) component of a trace event as the current pthread_id (that is, a pointer), or a real Linux thread ID.

Syntax:

mftrace.pthread_ids=bool

Parameter:

bool
  • True: evaluates $(THREAD) as the pthread_id.
  • False: evaluates $(THREAD) as a real Linux thread ID.

Default:

mftrace.pthread_ids=true

Comments:

Setting mftrace.pthread_ids=false makes CTF more readable when tracing programs with many threads, but comes with a small performance impact.

Examples:

To evaluate $(THREAD) to the real Linux thread ID:

...
mftrace.pthread_ids=false
...
