The time between the two measurements is being considered as down, because the monitor is still in an error condition. The time between the two measurements is being considered as down, because the error is now confirmed. For that, a double-check needs to be performed. The time between the two measurements is being considered as up, because it is not sure there is an actual error. If the unconfirmed error then is followed by a confirmed error, the whole time (OK -> unconfirmed -> confirmed) is considered as down. On a detailed level, the check results can change in these ways: However, all results can be broken down into the following situations: Of course, when continuously monitoring a service or server, there will be many check results in a row.

Is the time between an unconfirmed error and a confirmed error considered as up, or down? Go to a tile and open the three-dot menu to access the tile settings, including the different metrics you can select.
