crash pings contain a lot of information, some of which is surfaced in crash_summary. Whether the ping describes a shutdownkill is not something that's easy to tell. :gsvelto noted that the stackTraces.crash_info.type field would be EXCEPTION_BREAKPOINT for shutdownkill. This could be added to crash_summary. However, it's _just_ generic enough that I don't feel comfortable doing so. In contrast, "main" pings (serving the content_shutdown_crash counts to crash_aggregates and error_aggregates) have a direct line to shutdownkill via SUBPROCESS_KILL_HARD/ShutDownKill. Crash Stats has a similar direct annotation with ipc_channel_error=ShutDownKill. Crash pings deserves its own direct line to determine if it is describing this common (and usually ignorable) kind of crash. (Perhaps we just need to whitelist ipc_channel_error so it is included in crash pings' metadata? Then crash_summary gets it for "free") : http://searchfox.org/mozilla-central/source/dom/ipc/ContentParent.cpp#3028 : http://searchfox.org/mozilla-central/source/toolkit/components/crashes/CrashManager.jsm#227 : http://searchfox.org/mozilla-central/source/toolkit/crashreporter/client/ping.cpp#124
Whitelisting 'ipc_channel_error' should be trivial but it requires a data review.

Comment on attachment 8923792 [details] Data Collection Review Form 1. These will be added to crash pings. I assume this means they will follow standard Telemetry documentation standards. 2. Yes, people can opt out via data preferences and they are not required to submit crash reports. 3. Yes, chutten will be. 4. Category 1. 5. Default off, but data can be submitted via all channels and countries and locales. 6. No new identifiers. 7. Yes, this is covered. 8. A check in is not needed.
