Failed to allocate Injector, Error = INJECTOR_ERR_FAILED_TO_CREATE_REMOTE_THREAD

Uzair_A_ — Tue, 01 Mar 2016 04:13:17 GMT

I'm trying to use an evaluation version of VTune Amplifier XE for windows 2016 to profile my application which is a windows service.

I got the following collection log:

[Instrumentation Engine]:Failed to allocate Injector, Error = INJECTOR_ERR_FAILED_TO_CREATE_REMOTE_THREAD

Profiling Details:

OS: windows server 2008 R2
target type: Attach to Process
target is a running windows Service

Could you please help me on this? Thank you!

A simple solution is to use

A simple solution is to use hardware PMU event-based sampling, e.g. advanced-hotspots, general-exploration,... (with administrator privilege)

If you profile a windows service application with user-mode sampling (basic-hotspots, for example), read this article

Hi Peter,

Hi Peter,

Thanks for your prompt reply. Your post was very helpful and I was able to attach to my service and could profile it.
Now I have another doubt.
My whole application consists of a service and a file system filter driver.

Now, is it possible to do windows kernel profiling and specifically file system filter driver profiling with VTune?
Thanks in advance.

This is good news from you.

You may try advanced-hotspots (or other event-based sampling collectors) with "-analyze-system" option, after data collecting to open Bottom-up report, move to "bottom" called "Filter" panel to set "User/system functions", select module of your interest to filter data. I think that your *hot* driver should be there.

If your application have many waits e.g. disk IO, consider to use locksandwaits analysis to measure IO waits.
