# opamergeperf2(8)

## NAME

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 *running counters*

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.
