Processing type 115 SMF records

Use this topic as a reference for processing type 115 SMF records.

We must process any data you collect from SMF to extract useful information. When you process the data, verify that the records are from IBM MQ and that they are the records we are expecting.

Validate the values of the following fields:

  • SM115RTY, the SMF record number, must be X'73' (115)
  • SM115STF, the record subtype, must be 0001, 0002, 0005, 0006, 0007, 0201, 0215, or 0231

Reading from the active SMF data sets is not supported. We must use the SMF program IFASMFDP to dump SMF record to a sequential data set so that they can be processed. For more information see Use System Management Facility.

There is a C sample program called CSQ4SMFD which prints the contents of SMF type 115 and 116 records. The program is provided as source in thlqual.SCSQC37S and in executable format in thlqual.SCSQLOAD. Sample JCL is provided in thlqual.SCSQPROC(CSQ4SMFJ).
