CpuLoggingMask
This property specifies which process accounting and throttling fields should be written to the IIS log file. All enabled fields will be written on every process accounting log. All values logged are for the reset interval in which the logging occurs.
Note
Because process accounting in IIS uses Windows Job Objects to monitor CPU times for an entire process, process accounting will log and throttle only applications that are isolated in a separate process from IIS.
You can also change the logging mask flags by directly manipulating the flags contained in CpuLoggingMask by using the hexadecimal values described in the following tables.
Process throttling and process accounting are independently controlled by several other metabase properties. In order to enable process accounting you must set CpuEnableLogging (which is a member of CpuLoggingMask) to TRUE, and set at least one other CpuLoggingMask property to TRUE. It is also necessary to set at least one member flag of the CpuLoggingOptions, set CpuLoggingInterval to a nonzero value, and set either CpuAppEnabled or CpuCgiEnabled, as appropriate, to TRUE.
To properly activate process throttling, CpuLimitsEnabled must be set to TRUE, and at least one of the following properties should be set to TRUE: CpuLimitLogEvent, CpuLimitPriority, CpuLimitProcStop, or CpuLimitPause.

Not specified. |
Flag Name |
CpuEnableEvent |
|---|---|
Versions Applicable |
[IIS 5.0] |
Description |
Setting this flag to true indicates that the event that triggered the creation of a log record is specified in the log record itself. |

CpuEnableKernelTime |
|---|---|
Versions Applicable |
[IIS 5.0] |
Description |
Setting this flag to true indicates that total kernel-mode CPU time is recorded when process accounting is performed. |

Flag Name |
CpuEnableLogging |
|---|---|
Versions Applicable |
[IIS 5.0] |
Description |
Setting this flag to true indicates that process accounting is enabled for the Web service or server. Process accounting can log the amount of CPU time that is taken by a Web server or service, as well as any process throttling events that might occur. Because process accounting in IIS uses Windows Job Objects to monitor CPU times for an entire process, process accounting will log and throttle only applications that are isolated in a separate process from IIS. |
