What's Changed



Breaking changes


Refactored status to be a type. The Status type now implements the Stringer interface


Exit codes are now represented by a Status type instead of an integer. The previous constants have been replaced by this type. A constructor from an integer and string was added.


NewStatus(status int) (Status, error)
NewStatusFromString(status string) (Status, error)


The StatusText function was replaced by implementing the Stringer interface in the Status type


Removed ExitRaw, replaced by Exit


Exit is now the primary function to handle program exit and status code handling.


Removed Exitf, replaced by Exit and fmt.Sprintf


Exitf was removed and should be replaced by using Exit with fmt.Sprintf


// Was
check.Exitf(check.OK, "Everything is fine - answer=%d", 42)

// Now
check.Exit(check.OK, fmt.Sprintf("Everything is fine - value=%d", 42))


Rework ParseBytes to return uint64 instead of interface


ParseBytes now returns an uint64 instead of an interface. The BytesIEC and BytesSI types have been replaces by functions with the same name to get a string representation of a number of unit64 bytes.


b, err := ParseBytes("2MiB")
// uint64 2 * 1024 * 1024

fmt.Println(convert.BytesIEC(b))
// "2MiB"


The perfdata package was merged into the check package


// Was
perfdata := perfdata.PerfdataList{}

// Now
perfdata := check.PerfdataList{}


WorstState was moved from the result to the check package


The WorstState is now in the check package. Otherwise the function has not changed.


// Was
rc = result.WorstState(states...)

// Now
rc = check.WorstState(states...)


Refactored and concurrency-safe Overall


The Overall type has been overhauled.


The Add and AddSubcheck now both append a PartialResults to simplify the behavior the the internals. The Summary attribute was replaced by the OKSummary.


Overall is now concurrency-safe.
