Hi,

To give a little insight into our work and make our work more visible to
our Community we decided to create a  monthly report of what's going on in
the Sheriffs Team.

If you have questions or feedback, just let us know!

In case you don't know who the sheriffs are, or to check if there are
current issues on the tree, see:

Topics of this month!

4. Orange Factor
5. Contact

1. How-To article of the month and notable things!

-> In the Sheriff Newsletter we mentioned the "Orange Factor" but what is
this ?  It is simply the ratio of oranges (test failures) to test runs. The
ideal value is, of course, zero.

Practically, this is virtually impossible for a code base of any
substantial size,so it is a matter of policy as to what is an acceptable
orange factor.

It is worth noting that the overall orange factor indicates nothing about
the severity of the oranges. [4]

The main site where you can checkout the "Orange Factor" is at
https://brasstacks.mozilla.com/orangefactor/  and some interesting info's
are here https://wiki.mozilla.org/Auto-tools/Projects/OrangeFactor

-> As you might be aware Firefox OS has moved into Tier 3 Support [5] -
this means that there is no Sheriff Support anymore for the b2g-inbound
tree.

Also with moving into tier-3 - b2g tests have also moved to tier 3 and this
tests are by default "hidden" on treeherder. To view test results as
example on treeherder for mozilla-central you need to click on the checkbox
in the treeview "show/hide excluded jobs".

5.  How to contact us

There are a lot of ways to contact us. The fastest one is to contact
the sheriff on duty (the one with the |sheriffduty tag on their nick
:) or by emailing sheriffs @ mozilla dot org.

Cheers,
