| This metric is emitted every minute. It reports a number between 0 and 60 |
| which corresponds to the number of 1 second intervals during the monitored |
| minute to which a stalled foreground thread |
| ScopedBlockingCall(BlockingType::MAY_BLOCK) was attributed. A stalled call |
| is first attributed to the interval in which it began, and is attributed to |
| a number of intervals equal to the length of the call, rounded to the |
| nearest second. (Before http://crrev.com/c/2314873, the length was truncated |
| rather than rounded.) This aims to capture moments where the main thread is |

| This metric is emitted every 30 seconds [when there is user activity]. Each |
| 30 second duration is divided into 100ms intervals. This metric counts the |
| number of these intervals that were "janky". See |
| https://docs.google.com/document/d/1vDSGFvJblh7yJ3U3RVB_7qZLubyfTbQdQjuN1GoUNkc/edit |
| for more details. |
| |
| On desktop platforms, this metric measures native events, as well as tasks |
| posted to the UI and IO threads of the browser process. On Android, this |
| metric only measures tasks posted to the UI and IO threads. |
| |
| Update (October 27th 2019): The responsiveness::Watcher emitting this metric |
| previously started observation before the main message loop was running, |
| this resulted in the 99th percentile being mostly comprised of slow startups |
| (before the message loop gets to run). This was fixed and a fake-improvement |
| in the high percentiles is expected when the fix goes live. |
| |
| Update (M82 March 2020): Stopped recording background intervals on Android. |
| |
| Due to a bug, this metric does not measure long queueing time as jankiness. |
| It only measures jankiness as individual tasks taking a long time to run. |
| Given that it's a long-standing bug, this metric will not be modified. We |
| are testing a new metric |
| Browser.Responsiveness.JankyIntervalsPerThirtySeconds2 that correctly |
| accounts for queueing time. See |
| https://groups.google.com/a/google.com/forum/#!topic/chrome-scheduler/X32gKl6fW2A |
