CpuLoggingOptions
This property contains flags that specify how IIS should log CPU times for services, servers, or applications. You can use this property to configure IIS to sum the CPU times of CGI applications only, of ISAPI extensions and ASP applications only, or of all applications.
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 directly manipulate the bit flags within CpuLoggingOptions by using the hexadecimal values in the following Bitmask Values table.
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.
