Mozilla's Treeherder has an [intermittent failures dashboard](https://treeherder.mozilla.org/intermittent-failures/main?startday=2022-02-17&endday=2022-02-24&tree=trunk) that tracks flaky tests, [the display for a single issue](https://treeherder.mozilla.org/intermittent-failures/bugdetails?startday=2022-02-17&endday=2022-02-24&tree=trunk&bug=1692701) is a graph + table of failures.
