Nothing in the browser suite asked ipx, the directory or ipx-play for
their metrics, though production's Prometheus scrapes all three every
15 s and the dashboard and alerts go blank if one stops answering. The
suite's servers get metrics ports (8799, 8797, 8790) and one test reads
each gzipped, checks every sample line is one Prometheus can parse, and
looks for the series that show it works: ipx's request histogram with
the route just asked for, the directory's snapshot from ipx, ipx-play's
build. ipx's metrics.rs went from 9% to 86% of lines run by the suite.
