For now, App Usage Metrics doesn't record the app usage of the preview window, which is triggered by Marketplace.

We have two questions: 1) what is considered "preview"? -- When the item is highlighted in Marketplace and shown in the top area of the Marketplace UI? or when it is accessed by the user but not pinned? 2) This bug is specifically talking about App Usage metric in Firefox OS, but there is also the question of whether we need telemetry at the website/app level from *within* Marketplace (which we generally record via firing UA events from the UI, and then report on from Google Analytics).

since i was on bug 1237225, let me take a stab at answering this but let's hear it from Luke as well what we really want to understand is how frequent the apps (in the TV case, those hosted websites) are being used, similar to the idea of our mobile and mobile marketplace. It's just that apps on mobile can be packaged apps and for TV, it's just all hosted 1) i would say it is when it is accessed by the user but not pinned, though if we feel this is too much, we can discuss about making it record the app usage only when the TV websites are installed/pinned 2) the intention was simply to leverage what we are doing on mobile but if there are better ways to do so, open to it.

It's a TV specific feature [1]. The app will be launched immediately in a preview window on top of the Marketplace app (like a popup window) when the user clicks an app icon in Marketplace. Since users can really interact with that app, we'd like to treat it as a normal app and track its usage as well.

Yes, it's a good way to track actions that users do within Marketplace app. However, what we intend to collect is about other apps so I'm afraid Google Analytics doesn't suit this case. But it's still useful if we want to know how users use Marketplace app itself in the future.

Two things here: a. That "preview" happens on hover -- so basically, when I click across a row of apps, each gets "previewed." Is this what we would purport to track? That doesn't seem useful. b. If we want to track things in the pre-selected state, it sounds like we should track pinning and/or opening instead. But do we want to distinguish between pinning here, in Marketplace, vs pinning elsewhere in the TV?

The "preview" is *not* the screenshot shown in the Marketplace but the *popupwindow* launched outside of the Marketplace. You can simply treat that as a "auto-install, launch and auto-uninstall" flow. > b.

So, we do *not* intend to track things in the pre-selected state but to track an app is launching as usual.

Forgot to mention: This bug also addressed the issue in bug 1237225 since they're related problems.

Got it, thanks. Removing from Marketplace tree.

Verify this issue on both v2.5 and v2.6 latest build and the result is PASS. The usage of the preview windows and webistes from Marketplace can be recorded by metrics properly.
