If your site has one of the CICS reporting tools available (MXG, MICS, TDS, CICS PA, CA-JARS, SAS IT Resource Manager), then you would best use it to analyze the data.
If your site does not have one of the CICS reporting tools, you need to be aware that correctly interpreting the SMF type 110 records is NOT a simple task. You need to find and retain the dictionary record written each time the CICS region starts up (or when monitoring is turned on for the region) in order to correctly evaluate the various monitor components of the SMF 110 subtype 1 record. Furthermore, every recent version of CICS compresses its data so you need to run the SMF 110 records through the decompression routine before you attempt to use the dictionary to define and extract the data fields you're wanting. Tools like MXG do the decompression and matching for you automatically.
If you are going the do-it-yourself route, research DFHMNDUP and DFH$MOLS as you will become VERY familiar with them.
