Image Object
The Image performance object consists of counters that monitor virtual address
usage of images executed by processes on the computer.
No Access
Image Space is the virtual address space in use by the selected image with
this protection. No Access protection prevents a process from writing or reading
these pages and will generate an access violation if either is attempted.
Detail Level: Wizard
Counter Type: PERF_COUNTER_RAWCOUNT
Read Only
Image Space is the virtual address space in use by the selected image with
this protection. Read Only protection prevents the contents of these pages from
being modified. Any attempts to write or modify these pages will generate an
access violation.
Detail Level: Wizard
Counter Type: PERF_COUNTER_RAWCOUNT
Read/Write
Image Space is the virtual address space in use by the selected image with
this protection. Read/Write protection allows a process to read, modify and write
to these pages.
Detail Level: Wizard
Counter Type: PERF_COUNTER_RAWCOUNT
Write Copy
Image Space is the virtual address space in use by the selected image with
this protection. Write Copy protection is used when memory is shared for reading
but not for writing. When processes are reading this memory, they can share the
same memory, however, when a sharing process wants to have read/write access to
this shared memory, a copy of that memory is made for writing to.
Detail Level: Wizard
Counter Type: PERF_COUNTER_RAWCOUNT
Executable
Image Space is the virtual address space in use by the selected image with
this protection. Executable memory is memory that can be executed by programs, but
cannot be read or written. This type of protection is not supported by all
processor types.
Detail Level: Wizard
Counter Type: PERF_COUNTER_RAWCOUNT
Exec Read Only
Image Space is the virtual address space in use by the selected image with
this protection. Execute/Read Only memory is memory that can be executed as well
as read.
Detail Level: Wizard
Counter Type: PERF_COUNTER_RAWCOUNT
Exec Read/Write
Image Space is the virtual address space in use by the selected image with
this protection. Execute/Read/Write memory is memory that can be executed by
programs as well as read and written.
Detail Level: Wizard
Counter Type: PERF_COUNTER_RAWCOUNT
Exec Write Copy
Image Space is the virtual address space in use by the selected image with
this protection. Execute Write Copy is memory that can be executed by programs as
well as read and written. This type of protection is used when memory needs to
be shared between processes. If the sharing processes only read the memory,
then they will all use the same memory. If a sharing process desires write access,
then a copy of this memory will be made for that process.
Detail Level: Wizard
Counter Type: PERF_COUNTER_RAWCOUNT
