Hardware Keeping CPU Busy

This indication is sent when the queue length is normal but CPU usage is high and a high percent of the CPU is being used for interrupt requests. This keeps the CPU busy.

The indication has the following attributes:

PercentProcessorTime: The total current percentage usage of the CPU
PercentInterruptTime: The current percentage usage of the CPU as it handles interrupt requests
InterruptsSec: The number of interrupts per second that are passed to the CPU
Processor: The processor being monitored (Key attribute)

The indication is generated when the following thresholds are exceeded:

Threshold	Description	Default
High CPU Usage (HighCPUUsage)	This threshold indicates when a high percent of the CPU is being used. CPUs are expected to reach 100% marks quite often, but generally not expected to sustain that rate for an extended amount of time.	80
High CPU Usage Interrupt (HighCPUUsageInterrupt)	This threshold indicates when a high percent of the CPU is being used for interrupt requests, generally made by hardware devices.	20
High Interrupts per Second (HighInterruptsSec)	This threshold must not be exceeded.	600
N/A	The queue length must be normal.	N/A
Total CPUs Modifier (TotalCPUsMod)	This threshold must not be exceeded.	10

The following table shows the default settings for this indication:

Setting	Default
Send indications to Tivoli Enterprise Console	Yes
Send indications to Tivoli Business Systems Manager	No
Occurrences	15
Holes	3
