We don't want our performance or other telemetry data intermingling with desktops and vice versa. This bug is about making sure each browser reports an independent data set.
Looks like this will be ok despite our plans to share a profile. We should get some feedback from telemetry owners though to be sure. http://mxr.mozilla.org/mozilla-central/source/toolkit/components/telemetry/TelemetryPing.js#650 http://mxr.mozilla.org/mozilla-central/source/browser/metro/metroapp.ini.in In bug 784389 admin separated out "MetroFirefox" using the name/appid. We should be ok since we're not going to change these values in our app ini file.
#telemetry says we need to check with mreid.
mreid, We'd like to confirm that the telemetry data from metrofx is not getting mixed in with the desktop data. We're pretty sure it's fine, but we want to be really sure. I talked to :jonasfj today and he thinks it's probably ok as well, but wants to check with you. :jonasfj also raises the thought of splitting the metrofx data into a new folder; since we may see significant load when it goes out on GA. (He notes that everything except desktop & fennec end up in one folder). What are your thoughts?
Currently the Telemetry data layout separates "appName" into: [Firefox, Fennec, Thunderbird, Other]. MetroFirefox is indeed coming through separately from standard desktop Firefox, with an appName of "MetroFirefox", which gets bucketed into "Other". I agree that splitting MetroFx data into a separate folder is a good idea. Generally, anything we'll want to look at on it's own should be split out from "Other" (as long as it's relatively low-cardinality and not something that will explode the number of folders in the tree). We can do this as part of bug 933430.
Thanks Mark! We'll close this bug and look forward to bug 933430 landing.
