Please, I have several questions about the sensor indicated in subject
1) What is exactly the difference between "missing" and "hidden" updates?
2) What does it mean the default threshold value of 0,2 in, for instance, channel "Updates (Severity Critical) Hidden"?
3) What threshold value should I set if want to be alerted as soon as there is one pending Critical update with a scanning interval of 12 hours?
Thanks in advance.
