@ngyuki: which storage? pdo or mongodb?

[glensc]

seems to be the same problem: #146

[ngyuki]

@glensc Thank you for reply. I using mongodb.

#146 (comment)
Yes, xhgui assumes you have cpu profiling enabled throughout the code unfortunately.

If that is case, I think it would be more friendly if ProfilingFlags::CPU and ProfilingFlags::MEMORY could not be disabled.

[glensc]

Is the profiling even useful if you have not enabled any profiling flags?

I believe that just hiding the notices is not a solution. I think the saver here should reject incomplete profiles so they are not recorded at all.

[ngyuki]

I can only confirm it with tideways_xhprof, but even if all the flags are disabled, only the wall time is measured.

I think the problem is that the flag defaults to empty in php-profiler, so xhgui errors in that config.

[glensc]

so, only wall time is measured is actually useful?

[ngyuki]

It's same problem as #146, so I'll close it

[glensc]

I tested submitting only wall time, the output is useful. just cpu and mem columns are empty.
