Ask HN: Jenkins – tracking quantitative (error rate) test results

I'm using Jenkins to manage a CI pipeline.

Some of the tests I'm running return a quality indicator (specifically, a numeric bit error rate) alongside the pass/fail indication. This is to get a measure of how well a decoding and error correction algorithm works.

Now I'd like to keep track of the trend -- did a branch make the "noisy channel" performance better or worse?

Before I run away and write a log parser and report generator which spits out a HTML page -- does anyone know of an existing Jenkins plugin which can do this sort of parsing and trending/graphing?
