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