       opamergeperf2

       Merges  the  output  from two opaextactperf2 runs from the same fabric. Delta counters for matching links
       will be computed (before subtracted from after) and a CSV file equivalent to  opaextractperf2  's  output
       format will be generated suitable for importing into a spreadsheet or parsing by other scripts.

       NOTE:  The  before.csv  and after.csv input files must be generated from the same fabric, with before.csv
       containing counters prior to after.csv. Both files must  have  been  generated  to  contain  the  runningcounters

       without  any  counter  clears between before.csv and after.csv, and without using any interval options to
       opareport that might report delta counters, such as opareport -i or opareport with both --begin and --end
       options.
