Exit is a standalone exit function for simple checks without multiple results or perfdata.

NewCheck returns an empty Check object.

NewCheckWithOptions returns an empty Check object with caller-specified behavioural modifications.

NewDefaultStatusPolicy returns a status policy that assigns relative severity in accordance with conventional Nagios plugin return codes.

NewOUWCStatusPolicy returns a status policy similar to that returned by NewDefaultStatusPolicy with one difference: the UNKNOWN check status is demoted in severity such that any WARNING or CRITICAL check status will take priority.

NewPerfDatum returns a PerfDatum object suitable to use in a check result.

NewSimpleRangeFromFloat returns a new range object based on the two float values that were supplied.

NewStatusPolicy returns a status policy that assigns relative severity in accordance with a user-configurable prioritised slice.

ParseRange returns a new range object and nil if the given range definition was valid, or nil and an error if it was invalid.

RenderPerfdata accepts a slice of PerfDatum objects and returns their concatenated string representations in a form suitable to append to the first line of check output.
