    valueP float64 = 20
    maxP float64 = 100
    warningP float64 = 40
    criticalP float64 = 80
  )

  // check value against warning threshold and ignore critical, because it is NaN
  nagios.CheckThreshold("example", value, warning, critical)

  // check percentage calculated from valueP and maxP against warningP and criticalP thresholds
  nagios.CheckPercentageThreshold("percentage.example", valueP, maxP, warningP, criticalP)

  // add Ok
