check_x

Go Library to write Monitoring checks for Nagios/Icinga like checks

Usage:

func main() {
	//Set Plugin timeout, it will kill you and end properly
	check_x.StartTimeout(5 * time.Second)

	//Create a warning threshold
	warn, err := check_x.NewThreshold("10:")
	//If you don't want to handle the error, you could just pass it to the user
	check_x.ExitOnError(err)

	//Create a critical threshold
	crit, err := check_x.NewThreshold("@20:30")
	check_x.ExitOnError(err)

	//do your magic
	measuredValue1 := 25.0
	measuredValue2 := 5.0

	//evaluate your magic
	status1 := check_x.Evaluator{Warning: warn, Critical: warn}.Evaluate(measuredValue1)
	status2 := check_x.Evaluator{Warning: warn, Critical: warn}.Evaluate(measuredValue2)

	//see what went wrong
	worstState, err := check_x.States{status1, status2}.GetWorst()
	check_x.ExitOnError(err)

	//set some PerformanceData
	check_x.NewPerformanceData("foo", measuredValue1).Unit("B").Warn(warn).Crit(crit).Min(0).Max(100)
	check_x.NewPerformanceData("bar", measuredValue2).Unit("s").Min(0)

	//bring it to an end
	check_x.Exit(*worstState, "Made by check_x")
}

Critical - Made by check_x|'foo'=25B;10:;@20:30;0;100 'bar'=5s;;;0;
