The Windows Processes test reports additional statistics pertaining to processes running on Microsoft Windows systems.
Target of the test : A Windows host
Agent deploying the test : An internal agent
Outputs of the test : One set of results per process pattern specified
Measurement | Description | Measurement Unit | Interpretation |
---|---|---|---|
Number of processes running |
Indicates the number of processes that are currently running. |
Number |
|
Handle count |
Indicates the number of handles opened by the process. |
Number |
An increasing trend in this measure is indicative of a memory leak in the process. |
Number of threads |
Indicates the number of threads that are used by the process. |
Number |
|
Virtual memory used |
Indicates the amount of virtual memory that is being used by the process. |
MB |
|
I/O data rate |
Indicates the rate at which processes are reading and writing bytes in I/O operations. |
Kbytes/Sec |
This value counts all I/O activity generated by each process and includes file, network and device I/Os. |
I/O data operations |
Indicates the rate at which the process is issuing read and write data to file, network and device I/O operations. |
Operations/Sec |
|
I/O read data rate |
Indicates the rate at which the process is reading data from file, network and device I/O operations. |
Kbytes/Sec |
|
I/O write data rate |
Indicates the rate at which the process is writing data to file, network and device I/O operations. |
Kbytes/Sec |
|
Page fault rate |
Indicates the total rate at which page faults are occurring for the |
Faults/Sec |
A page fault occurs when a thread refers to a virtual memory page that is not in its working set in main memory. This may not cause the page to be fetched from disk if it is on the standby list and hence already in main memory, or if it is in use by another process with |
Memory working set |
Indicates the current size of the working set of a process. |
MB |
The Working Set is the set of memory pages touched recently by the threads in the process. If free memory in the computer is above a threshold, pages are left in the Working Set of a process even if they are not in use. Comparing the working set across processes indicates which process(es) are taking up excessive memory. |
