start process to send email notifications upon btrfs problems?

[testbird]

I am wondering how btrfs users can ensure to automatically get notified (only) upon errors and warnings (that usually happen in the background and are very likely to remain unnoticed).

Btrfsmaintenance seemed like good find for this, it covers the necessary background tasks.

But couldn't it also run something like a watchdog task (i.e. bash pipe)?
It could filter the log for any btrfs warnings and errors that may occur during the daily usage, and send out emails as soon as they occur.
