* A mozilla-central push results in ~400 jobs. The typical OrangeFactor across all trunk trees is normally (excluding the recent spike) 3-4, ie: a failure rate of ~1%.

* Therefore as a rough guide a new platform/testsuite must have at most a 5% per job failure rate initially, and ideally <1% longer term.

* However, sheriffs will make the final determination of whether a job type has too many intermittent failures. This will be a based on a combination of factors including failure rate, length of time the failures have been occurring, owner interest in fixing them & whether TBPL is able to make bug suggestions.

* To see it, append '&showall=1' to the URL ({{bug|748833}} will add a checkbox for this to the TBPL UI). #TODO: update this for Treeherder.
* To see it, click the "show/hide hidden jobs" checkbox to the left of the quick filter input field in the Treeherder UI. ({{bug|1078081}} will add URL parameter support for this soon).
* To filter the jobs displayed, under the 'Filters' menu use the 'job name' field (which supports regexp).

* For Try specifically, you can request that the job type by made non-default (ie requires explicit opt-in when using trychooser syntax, and won't be scheduled with '-u all' or similar), in order to be shown in the default view on Try - [http://hg.mozilla.org/build/buildbot-configs/file/27dff21cb799/mozilla/config.py#l332 example].
