Have we discussed this project with the metrics team yet?
When I started looking into this it wasn't clear to me that people really knew
what they wanted
Cool. Perhaps we should start out with collecting stories/examples:
* how people currently use the Telemetry UI
* data people wish they had from Telemetry but required either custom
reports or is unavailable
I myself have the following examples:
Distribution of Flash versions: we wanted to know the distribution of
Flash versions on various channels, limited on to Windows. This data was
used to guide the following projects:
* encouraging users on the aurora/beta channels to install the Flash
beta channel, but making sure that we still had enough users on the
Flash release channel
* planning the deployment of click-to-play blocklisting and monitoring
its effectiveness
This data is currently being collected by a custom cronjob, published as
CSV, and is now being reported via a custom UI here:
https://crash-analysis.mozilla.com/bsmedberg/flash-distribution.html
I'm also working on correlating this against the crash counts and ADU
counts for each channel to give us a "crashiness of Flash versions"
comparison metric that we can use for Flash betas.
Monitoring a specific technical detail about plugin scripting: we
weren't sure whether plugin elements needed to support direct calling
via NPAPI. So in bug 827158 bz is adding a telemetry probe which would
indicate whether a plugin element was ever actually called. We intend to
check whether there are any hits on this probe once it gets to beta/release.
I am hoping to use telemetry soon to measure the frequency where we hit
"no active Flash instances running". If users hit 0 instances regularly,
this will allow us to potentially restart the Flash process more often
and work around memory leaks and other slow behavior.
I really have never used the telemetry UI frontend. I never quite
understood how to construct interesting data from it.
