3 In Icinga 2 active check freshness is enabled by default. It is determined by the
4 `check_interval` attribute and no incoming check results in that period of time.
6 threshold = last check execution time + check interval
8 Passive check freshness is calculated from the `check_interval` attribute if set.
10 threshold = last check result time + check interval
12 If the freshness checks are invalid, a new check is executed defined by the
13 `check_command` attribute.
