Method Detail

getDerivedGauge

@Deprecated
Number getDerivedGauge()

Deprecated. As of JMX 1.2, replaced by getDerivedGauge(ObjectName)

Gets the derived gauge.

Returns:

The derived gauge.

---

getDerivedGaugeTimeStamp

@Deprecated
long getDerivedGaugeTimeStamp()

Deprecated. As of JMX 1.2, replaced by getDerivedGaugeTimeStamp(ObjectName)

Gets the derived gauge timestamp.

Returns:

The derived gauge timestamp.

---

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.

See Also:

getNotifyHigh()

---

getNotifyLow

boolean getNotifyLow()

Gets the low notification's on/off switch value.

Returns:

true if the gauge monitor notifies when exceeding the low threshold, false otherwise.

See Also:

setNotifyLow(boolean)

---

setNotifyLow

void setNotifyLow(boolean value)

Sets the low notification's on/off switch value.

Parameters:

value - The low notification's on/off switch value.

See Also:

getNotifyLow()

---

getDifferenceMode

boolean getDifferenceMode()

Gets the difference mode flag value.

Returns:

true if the difference mode is used, false otherwise.

See Also:

setDifferenceMode(boolean)

---

setDifferenceMode

void setDifferenceMode(boolean value)

Sets the difference mode flag value.

Parameters:

value - The difference mode flag value.

See Also:

getDifferenceMode()
