Understanding calculation for link availability
I am trying to understand the Orange state in link availability. In the release note 21.1.1, it mentioned "health of the link based on the SLA metrics received from the site and controller for each WAN link of the site. SLA metric values are used to determine whether the state is up, down, degraded"
How is the SLA metrics calculated and is it customizable to tune the sensitivity? Does SLA metric to different branch location impacts the SLA link availability graph?
