Description

The crash stats for 3.6.13 are way too low:

Looks like this has been happening for a while:

Might just be those views, looks like there is more volume on http://crash-stats.mozilla.com/topcrasher/byversion/Firefox/3.6.13

Christian, what is the issue exactly?  The number of crashes submitted?  The average number of crashes per user?  Can you give us more specifics about which values are way too low and what you're expecting them to be?

The magnitude of crashes is off. Normally branch releases hover around 2 crashes / ADU. Right now we're at .16 crashes / ADU. That means either we somehow gained a bunch of ADUs without them crashing (unlikely), the crashes aren't being counted/recorded, or there is some throttle funkiness.

Looking at http://crash-stats.mozilla.com/daily?p=Firefox&v[]=3.6.13 the ADUs look sane / in the typical range we see, it's the crashes that look artificially low.

Digging deeper, on http://crash-stats.mozilla.com/daily?p=Firefox&v[]=3.6.13, when I click generate (I guess applying the 10% throttle) everything goes back to looking normal. When I go to the admin side and try to edit 3.6.13 it already says the throttle is 10 though. I can't set the throttle on some views (like http://crash-stats.mozilla.com/products/Firefox/versions/3.6.13) so they are "broken" to me.

I'm bumping this down from a blocker because I think data isn't being lost.

Is the throttle set to the right value?  It's currently set to 10% in the admin / branches page as the default value to be used by ADU.  If we bump that to 100% then the value shifts to 1.6 crashes per active daily user.

It should be at 10% (bug 617968).

Comment 6

[Laura Thomson :laura]

It's correct at 10% in the collector config, just checked.  Seems like some of the graphs have it at 100% though.

Comment 7

[Ryan Snyder [:ryansnyder] [:rsnyder] [:rysny]]

Hm, yeah, it looks like ADU values are being calculated at 100% instead of the default value associated with Firefox 3.6.13 (10%).  Updating ticket title accordingly.

Whew, glad we're not losing data :-)

I'll take a look at this for 1.7.7.  We should be able to ship 1.7.7 shortly after the PHX migration.
