Channel Path Activity - SMF record type 73

One qualifier is possible:

cpid: A two-digit hexadecimal number that identifies a channel path.
cptype: Channel path type (as contained in SMF73ACR) enclosed in quotes.

For overview processing, one qualifier is required. If it is omitted for exception reporting, the threshold applies to all channel paths in the SMF record.

For most conditions, there exist two condition names. The second in the list has always the prefix CHG (instead of CH for the first one — to be used with the qualifier cpid) and has to be used with the qualifier cptype. This condition can be used for channels that are under control of Dynamic Channel Path Management (DCM). All channels of the specified type will be accumulated and then processed. Therefore, the formulas for the algorithm contains summary values instead of single-channel values, for example:

(SMF73TUT*100)/SMF73PTI*8              see CHTBSY(cpid)		
(Sum(SMF73TUT)*100)/Sum(SMF73PTI*8)    see CHGTBSY(cptype)

Condition	Condition Name	Qualifier	Source	Algorithm (depending on channel type)
For processors earlier than z990, use the following condition if CPMF is not available or for CPMF compatibility mode:
Percent channel busy	CHPBSY CHGPBSY	cpid cptype	SMF73BSY SMF73SMP	(BSY*100)/SMP Note: In case of monitoring z990 hardware, both fields are zero.
