Hi, I try to collect some trace to understand some behaviors in webkit. I see that Xcode provides some os logging methods, and one is call "os_signpost". So I insert those trace functions in source codes and try to use Instruments to collect some trace. No error goes out but I cannot capture any reserved critical events displayed in Instruments.
Is os_signpost supported in webkit? If not, what other tools could we use to capture some start and end times of interested events?
Thanks

Could you please reach out via one of the help channels listed at <https://webkit.org/getting-started/#staying-in-touch>?
Since this is a question and there is no indication of a WebKit bug, resolving this bug report as invalid.
