What is your plan for understanding this action?  Typically, I'd recommend using
a histogram, and building in a baseline to compare against.  Histograms are more
space-efficient, and have better dashboard support to boot.

[Mike Lerman, 2015/05/21 20:38:09]

Anything non-zero tells us that browsers are being opened for the system
profile. We expect and want this number to be zero, otherwise wonky things are
happening that should be followed up.

I expanded the description somewhat.

[Ilya Sherman, 2015/05/21 21:18:14]

I'd still recommend a histogram -- probably associated with the BooleanHit enum
-- rather than an action.  However, if you really prefer to use an action, it's
okay if you do so, in which case LGTM.

[Mike Lerman, 2015/05/25 10:41:29]

I just need to know if there's a non-zero number of triggers or not, and the
filter based off OS and Milestone that's present is all I need. I'll go with
this - thanks!

Could you please upload a separate CL to fill in the missing pieces of
actions.xml?  You can TBR me on it if you'd like, but it would be nice not to
muddy this CL with all of these unrelated changes.  Also, could you please file
a bug tagged with "Internals-Metrics" to investigate why our presubmit scripts
didn't catch these in the first place?  Thanks.

[Mike Lerman, 2015/05/21 20:38:09]

Sure.
