CpuLimitLogEvent

This property specifies the percentage of CPU time, in 1/1000ths of a percent, that all isolated processes on the Web server are allowed to occupy during a given process accounting interval (specified by CpuResetInterval). If the processes attempt to occupy more CPU time than specified in CpuLimitLogEvent, a note will be made in the Windows Event Log that the processes have exceeded the limits. If process accounting is enabled, the limit overrun will also be entered into the IIS log.

If CpuLimitLogEvent is set to 0, or a value greater than 100,000 (100 percent), IIS will not log any events against the process. However, one of the other process throttling properties, such as CpuLimitPriority, CpuLimitProcStop, or CpuLimitPause, could generate a response from IIS if a CPU limit is exceeded.

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 flag of 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.

Important Note:
Applications that do not have process throttling enabled do not contribute to the total CPU time for the purposes of calculating CPU limit overruns.
