Stop Causes
Configuration
Here is a short video, in French, on how you can configure them.
Stop cause as uptime
It can happened that you want to classify stop in your production, but count it as uptime.
With that option, you could classify a minor stop, see it in your reports and your Timeline tile, but not actually lower your availability. This option has to be use with precaution, because if you use it too much, your calculated availability will not correspond to your actual machine availability.
