Then calculate the delta and do something with it (print it, aggregate it, whateva). In the return, make sure you have a starting timestamp recorded (this avoids race conditions if the script is run if the function is currently in-flight). To time stuff in DTrace, get the timestamp (wall-clock time) or vtimestamp (on-CPU time) in the entry. Sure enough, it's the MacAppStore program, downloading updates even though it's been told not to. Sudo dtrace -q -n 'syscall::open*:entry/execname="backupd"/ 'ĭtrace: description 'syscall::read:entry ' matched 1 probeĭtrace: description 'syscall::read_nocancel:entry ' matched 1 probe Seeing what time machine is looking at Ĭurious what Time Machine is looking at while doing backups?

Participants use the free eClicker Audience app, or their device’s web browser, to view and answer the questions, right on their smartphone, tablet or laptop. Teachers and presenters use the eClicker Presenter app to enter questions and begin the polling. To work around this, let the function you're tracing do its work, cause the fault of the data into memory, then access the data in the :::return clause. eClicker Presenter is made up of two parts: the Presenter and the Audience. This can happen if you're accessing the data in an :::entry clause before the data is used. This happens because the page in question hasn't been faulted in yet, or in general isn't available to the kernel or DTrace at this moment.

(In case the quickies stripped off the backslashes, it's three backslashes, then a space, then Presenter) You might want to run dtrace against an program, which might has a space in the name:ĭtrace -n 'objc$target:NSUndoManager*:+alloc:entry' -c `pwd`/eClicker Presenterĭtrace: failed to execute /Users/markd/Library/Developer/./eClicker: file is set-id or unreadableīut it's right there!
