Configure Perf Collection (CFGPFRCOL)

The Configure Performance Collection (CFGPFRCOL) command changes certain collection attributes and determines how Collection Services will manage data collection. Some attributes changed with this command will take effect immediately, while others will take effect the next time a collection object is created. See the parameter help to determine how each attribute will be handled. The Collection Services server job (QYPSPFRCOL) can be started or cycled by using the Start Performance Collection (STRPFRCOL) command.

Parameters

Default interval (INTERVAL)

Specifies the default collection interval (in minutes). This value is used by most data categories as the collection sample interval. When a category has a minimum or maximum interval size associated with it and it also uses the default collection interval, the default interval will be used as long as it does not conflict with those other settings. When there is a conflict, the minimum or maximum will be used. For example the maximum interval size is five minutes for *DISK and *IPCS. If the default collection interval is set to a value larger than five minutes, the category will still collect at five minute intervals. This change will take effect immediately.

*SAME

The value does not change. If the value has never been modified, the interval will be 15 minutes.

0.25

The default collection interval will be 15 seconds.

0.5

The default collection interval will be 30 seconds.

1.0

The default collection interval will be 1 minute.

After the retention period has expired, the object will be automatically deleted by the Collection Services server job (QYPSPFRCOL). Expired collections are removed from the system each time a collection starts or cycles. Collection objects will be automatically deleted only when they exist in the system's configured collection library. This change will take effect immediately and will apply to the current and future collection objects.

Examples

Example 1: Configuring Default Interval and Collection Library

CFGPFRCOL INTERVAL(5) LIB(QMPGDATA)

This command will cause the default interval at which most sample data is collected to be changed immediately to 5 minutes. In addition, the library where data is collected will change to QMPGDATA the next time a management collection object (*MGTCOL) is created.

Example 2: Configuring Cycle Time and Cycle Interval

CFGPFRCOL CYCTIME(030000) CYCITV(6)

This command will change the cycle time and cycle interval of the collection. The base cycle time will be 3:00 a.m. and the collection will cycle every six hours from the base time. New management collection objects (*MGTCOL) will be created at the following times: 3:00, 9:00, 15:00, 21:00, 3:00, 9:00, and so on.

Example 3: Configuring Retention Period

CFGPFRCOL RETPERIOD(25 *DAYS)

This command will cause the current and future collection objects to be retained on the system for 25 days before being automatically deleted by the Collection Services server job (QYPSPFRCOL).

Example 4: Configuring Default Collection Profile and Create Database Files

CFGPFRCOL DFTCOLPRF(*STANDARD) CRTDBF(*YES)

This command causes changes that will take effect the next time a management collection object (*MGTCOL) is created. At that time, the collection profile will change to *STANDARD and the Create Performance Data (CRTPFRDTA) job will be submitted.

Example 5: Configuring System Monitoring Support

CFGPFRCOL ENBSYSMON(*YES) SYSMONCGY((*SYSLVL .25) (*DISK .5)
                                    (*JOBMI 1) (*JOBOS 1))

This command enables system monitoring support the next time the collection is cycled or the collector is started. Data associated with the *SYSLVL category is collected at 15 second intervals, *DISK category data is collected at 30 second intervals, and job data (*JOBMI and *JOBOS categories) is collected at one minute intervals.

The CRTPFRDTA2 job will be submitted creating a system monitor collection that includes only these categories. The QAPMSMSYS, QAPMSMDISK, QAPMSMJMI, and QAPMSMJOS files will also be produced.
