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.
