DCMT VARY STATISTICS Command

The DCMT VARY STATISTICS command has been enhanced to let you vary the time of day and day interval when statistics are written and reset.

DCMT VARY STATISTICS Syntax

The following syntax shows updates to the DCMT VARY STATISTICS command.

DCMT VARY STATISTICS Parameters

This section describes the new parameters for the DCMT VARY STATISTICS command:

ROLl

Varies the interval at which statistics are written to the log file and reset.

TIMe interval-roll-time

Specifies time of day in twenty-four hour format (HH:MM) format at which statistics are written to the log and reset.

FREquency day-frequency

Specifies the day frequency at which statistics are written to the log and reset.

NOROLl

Varies the system not to perform statistics interval roll.

Example: Changing Interval Roll Time and Day Frequency

The following example shows how the roll interval was changed to 8:30 p.m., each seventh day:

DCMT V STATISTICS ROLL TIME 20:30 FREQUENCY 7
STATISTICS INTERVAL ROLL WAS OFF
CHANGED TO 20:30 FREQUENCY IS 7   DAY(S)

The following example shows how the day frequency was changed to 10 days:

DCMT V STATISTICS ROLL FREQUENCY 10
STATISTICS INTERVAL ROLL TIME WAS 20:30 INTERVAL WAS 7   DAY(S)
CHANGED TO 20:30 FREQUENCY IS 10  DAY(S)

The following example shows how the roll interval was changed to 10:00 p.m., day frequency is unchanged:

DCMT V STATISTICS ROLL TIME 22:00
STATISTICS INTERVAL ROLL TIME WAS 20:30 INTERVAL WAS 10  DAY(S)
CHANGED TO 22:00 FREQUENCY IS 10  DAY(S)

The following example shows how to disable interval roll:

DCMT V STATISTICS NOROLL
STATISTICS INTERVAL ROLL TIME WAS 22:00 INTERVAL WAS 10  DAY(S)
CHANGED TO NOROLL

The following example shows how to enable interval roll with the last used values:

DCMT V STATISTICS ROLL
STATISTICS INTERVAL ROLL WAS OFF
CHANGED TO 22:00 FREQUENCY IS 10  DAY(S)
