My iOS app is making too many calls to stat(), but I can’t find a good way to trace them with Instruments:
- The I/O Activity instrument, to my surprise, doesn’t show stat/lstat/fstat, although it does show most other filesystem calls.

Figured it out: The solution is to select the I/O Activity instrument, and under “Active Probes” check the box labeled “Stats”.

See, it’s another terrible UI! How was I supposed to notice the word “stat” there when they capitalized it and appended an “s”? Grumble grumble... O_o
