high frequency failures of branch scanning is not alerted to ops

Bug Description

Per today's canonical-launchpad thread "package-importer restart", it seems we don't have anything that alerts us if the branch scanner suddenly starts failing to scan many branches, as happened in bug 715000. We should expect some amount of failure through environmental errors but a sudden spike probably indicates something we should investigate.

I'm going to drop this to low; while its a value report, we've been very happy with the overall reporting in place for this subsystem so far, and I doubt we'd get to this within 6 months.

That's true. However, if thousands of branches are failing, something's probably wrong beyond just normal background radiation. I agree with putting it to Low.

Changed in launchpad:
importance: High → Low
