    • Method Detail

      • getDerivedGauge

        Number getDerivedGauge(ObjectName object)
        Gets the derived gauge for the specified MBean.
        Parameters:
        object - the MBean for which the derived gauge is to be returned
        Returns:
        The derived gauge for the specified MBean if this MBean is in the set of observed MBeans, or null otherwise.
      • getDerivedGaugeTimeStamp

        long getDerivedGaugeTimeStamp(ObjectName object)
        Gets the derived gauge timestamp for the specified MBean.
        Parameters:
        object - the MBean for which the derived gauge timestamp is to be returned
        Returns:
        The derived gauge timestamp for the specified MBean if this MBean is in the set of observed MBeans, or null otherwise.
      • getHighThreshold

        Number getHighThreshold()
        Gets the high threshold value.
        Returns:
        The high threshold value.
      • getLowThreshold

        Number getLowThreshold()
        Gets the low threshold value.
        Returns:
        The low threshold value.
      • setThresholds

        void setThresholds(Number highValue,
                           Number lowValue)
                    throws IllegalArgumentException
        Sets the high and the low threshold values.
        Parameters:
        highValue - The high threshold value.
        lowValue - The low threshold value.
        Throws:
        IllegalArgumentException - The specified high/low threshold is null or the low threshold is greater than the high threshold or the high threshold and the low threshold are not of the same type.
      • getNotifyHigh

        boolean getNotifyHigh()
        Gets the high notification's on/off switch value.
        Returns:
        true if the gauge monitor notifies when exceeding the high threshold, false otherwise.
        See Also:
        setNotifyHigh(boolean)
      • setNotifyHigh

        void setNotifyHigh(boolean value)
        Sets the high notification's on/off switch value.
        Parameters:
        value - The high notification's on/off switch value.

      • getDifferenceMode

        boolean getDifferenceMode()
        Gets the difference mode flag value.
        Returns:
        true if the difference mode is used, false otherwise.
