What are the differences between confirmed errors and unconfirmed errors?
When a check is performed on a monitor, the first probe will return a pass or fail. If the first probe returns a timeout, this is classified as an unconfirmed error.
This is followed by a second probe immediately run after the first check and usually from a different checkpoint. If this probe returns a timeout result as well, then the result of the check is a confirmed error. However, if this probe returns successfully, then the first error seen previously will remain as an unconfirmed error.
