Record type 73 (X'49') — RMF Channel Path Activity

For information on using RMF, see z/OS RMF Reporter User's Guide.

For information on Monitor I and II, see z/OS RMF Report Analysis.

Record type 73 is written when channel path activity measurement is requested. Entries are created for all 256 theoretical possible channel paths in the system.

As with all records produced by RMF, this record contains a header section followed by the RMF Product section. These are followed by:

Channel Path control section: Identifies number of times any channel path was busy. The SMF73CFL flag byte indicates (X'08') whether the record might include data sections that are not valid.
Channel Path data section: Identifies and gives information on each channel path. The SMF73FG3 flag byte indicates (X'02') whether the channel path is a real entry. This is of relevance only if the channel path control section indicates that invalid entries might occur.

Macro to Symbolically Address Record Type 73: The SMF record mapping macro for all records produced by RMF is ERBSMFR. Its format is ERBSMFR (n1,n2,...) where n1, n2, ... are the SMF record types you want to map. Note that the parentheses are required only when two or more record types are specified. The mapping macro resides in SYS1.MACLIB.
