3.2.1 Processor monitoring definition examples

This subsection describes examples of definitions for processor monitoring.

Organization of this subsection

(1) Monitoring template
(2) Definition examples other than for monitoring templates

(1) Monitoring template

(a) Processor-related monitoring template alarms

Processor-related alarms in the monitoring template are stored in the alarm table for PFM UNIX Template Alarms [CPU] 09.00.

Table 3‒7: Processor-related monitoring template alarms
Monitoring template alarm	Record	Field	Error threshold	Warning threshold	Description
Kernel CPU	`PI`	`Kernel` `CPU` `%`	> 75	> 50	If the percentage of time during which the processor operates continues to be above the threshold, there might be a problem with the OS or the operation method.^#
User CPU	`PI`	`User` `CPU` `%`	> 85	> 65	If the percentage of time during which the processor operates continues to be above the threshold, there might be a problem with a specific application.^#
Run Queue	`PI`	`5-Minute` `Run` `Queue` `Avg`	> 8	> 4	If the average number of threads is above the threshold, there might be a problem with the OS, operation method, or a specific application.^#
CPU Per Processor(K)	`PI_CPUP`	`Processor ID`	>= 0	>= 0	If the CPU usage continues to be at or above the threshold, there might be a problem with the OS or operation method.
CPU Per Processor(K)	`PI_CPUP`	`System %`	> 75	> 50
CPU Per Processor(U)	`PI_CPUP`	`Processor ID`	>= 0	>= 0	If the CPU usage continues to be at or above the threshold, there might be a problem with a specific application.
CPU Per Processor(U)	`PI_CPUP`	`User %`	> 85	> 65

#: Any processes that are excessively using the processor must be found, and appropriate action must be taken. If no such processes exist, operations that outstrip the kernel's scheduling capabilities, such as the generation and deletion of many processes in a short time, might be occurring. In such a case, because the system environment is not adequate for the processing, you might need to upgrade the processor or add processors.

If you want to perform more detailed monitoring of processor performance you can use your own alarms or reports in addition to the existing alarms. For details about how to create your own alarms or reports, see 3.1.1(2) Monitoring methods.

For details about the settings for the existing alarms, see 8. Monitoring Templates.

(b) Processor-related monitoring template reports

Table 3‒8: Processor monitoring template reports
Report name	Displayed information
CPU Per Processor Status	Real-time information about the processor status
CPU Per Processor Usage	Real-time information about the CPU usage for a processor
CPU Trend	Daily CPU usage for a host for the last month
CPU Usage Summary	A history of the CPU usage on a minute-by-minute basis for the last hour
CPU Status(Multi-Agent)	An hourly history of the CPU usage by multiple hosts for the last 24 hours
CPU Status	Real-time information about the CPU usage
CPU Trend(Multi-Agent)	A daily history of the CPU usage by multiple hosts for the last month

For details about settings for existing reports, see 8. Monitoring Templates.
