Description |
Measurement
Unit |
Interpretation |
| No_of_processes |
The number of w3wp.exe processes that are currently running in the application pool |
Number |
A zero value in this measure indicates that the application pool is crashed. |
| Cpu_util |
The percentage CPU utilization of the application pool |
Percent |
A higher value indicates excessive CPU utilization. |
| Memory_util |
The percentage of total memory utilized by the application pool |
Percent |
If the value of this measure consistently increases, it indicates a memory bottleneck. |
| No_of_threads |
The number of threads that are currently active in the application pool |
Number |
This is an indicator of the workload on the pool. |
| No_of_handles |
The number of handles currently opened by the application pool |
Number |
|
| Page_faults |
The rate of page faults happening in the application pool |
Faults/Sec |
Ideally, this value should be low. |
| Private_data |
The data that the application pool has currently allocated and cannot be shared with other application pools |
MB |
A gradual growth in this measure indicates a memory leak in the websites that are running in the application pool. |
| Pool_paged_data |
The amount of memory currently allocated from the paged pool. The Paged Pool is an area of the System's virtual memory that is limited in size and used for various system related functions. |
MB |
A gradual growth in this measure indicates a memory leak in the websites that are running in the application pool. |
| Pool_non_paged_data |
The amount of memory currently allocated from the non-paged pool. The Non-Paged Pool is an area of the System's virtual memory that is limited in size and used for kernal and device driver functions. |
MB |
A gradual growth in this measure indicates a memory leak in the websites that are running in the application pool. Running out of space in the nonpaged pool often results in a Blue Screen. |
| IO_reads |
The rate at which the W3WP.exe process is reading data from I/O operations |
KBytes/Sec |
|
| IO_read_operations |
The rate at which the W3WP.exe process is issuing read I/O operations |
Operations/Sec |
|
| IO_writes |
The rate at which the W3WP.exe process is writing data into I/O operations |
KBytes/Sec |
|
| IO_write_operations |
The rate at which the W3WP.exe process is issuing write I/O operations operations |
Operations/Sec |
