Quering since when a PG is inactive

[Wido den Hollander <wido@42on.com>]

Hi,

I'm working on a patch in PGMonitor.cc that sets the state to HEALTH_ERR
if >= X PGs are stuck non-active.

This works for me now, but I would like to add a timer that a PG has to
be inactive for more than Y seconds.

The PGMap contains "last_active" and "last_clean", but these timestamps
are never updated. So I can't query for last_active =< (now() - 300) for
example.

On a idle test cluster I have a PG for example:

"last_active": "2015-12-09 02:32:31.540712",

It's currently 08:53:56 here, so I can't check against last_active.

What would a good way be to see for how long a PG has been inactive?
