Method Detail

getDerivedGauge

public Number getDerivedGauge()

Deprecated. use getDerivedGauge(ObjectName)

Retrieves the derived gauge.

Returns:

the derived gauge.

---

getDerivedGaugeTimeStamp

public long getDerivedGaugeTimeStamp()

Deprecated. use getDerivedGaugeTimeStamp(ObjectName)

Retrieves the derived gauge timestamp.

Returns:

the derived gauge timestamp.

---

getDerivedGauge

public Number getDerivedGauge(ObjectName name)

Retrieves the derived gauge.

Parameters:

name - the object name of the mbean.

Returns:

the derived gauge.

---

getDerivedGaugeTimeStamp

public long getDerivedGaugeTimeStamp(ObjectName name)

Retrieves the derived gauge timestamp.

Parameters:

name - the object name of the mbean.

Returns:

the derived gauge timestamp.

---

getHighThreshold

public Number getHighThreshold()

Retrieves the high threshold. REVIEW: zero threshold

Returns:

the high threshold value, zero means no threshold.

---

getLowThreshold

public Number getLowThreshold()

Retrieves the low threshold. REVIEW: zero threshold

Returns:

the low threshold value, zero means no threshold.

---

setThresholds

public void setThresholds(Number highValue,
                          Number lowValue)
                   throws IllegalArgumentException

Sets the high and low threshold. REVIEW: zero threshold

Parameters:

highValue - the high threshold value, pass zero for no high threshold.

lowValue - the low threshold value, pass zero for no low threshold.

Throws:

IllegalArgumentException - when either threshold is null or the high threshold is lower than the low threshold or the. thresholds have different types.

---

getNotifyHigh

public boolean getNotifyHigh()

Retrieves the high notify on/off switch.

Returns:

true if high notifications occur, false otherwise.

---

setNotifyHigh

public void setNotifyHigh(boolean value)

Sets the high notify on/off switch.

Parameters:

value - pass true for high notifications, false otherwise.

---

getNotifyLow

public boolean getNotifyLow()

Retrieves the low notify on/off switch.

Returns:

true if low notifications occur, false otherwise.

---

setNotifyLow

public void setNotifyLow(boolean value)

Sets the low notify on/off switch.

Parameters:

value - pass true for low notifications, false otherwise.

---

getDifferenceMode

public boolean getDifferenceMode()

Retrieves the difference mode flag.

Returns:

true when in difference mode, false otherwise.

---

setDifferenceMode

public void setDifferenceMode(boolean value)

Sets the difference mode flag.
