Oper State
The state of an instance of a monitor as represented by a row in this table. If
the state is notInUse, then the row is available.
Estimate Of Mean
A weighted average computed using the exponentially weighted moving
average (EWMA). This attribute may be set or reset while the
ewmaMmAdministrative state is lock.
Estimate Of Variance
An estimate of the variance of Estimate Of Mean calculated by using a
different equation that gives the effect of exponential weighting.
MovingTime Period
This attribute provides a value that is greater than or equal to and in the
same units as Granularity Period. It is a constant used in the calculation of
the EWMA.
Granularity Period
This object is used to specify the period between observations of the observed
object. The unit of time may be seconds, minutes, hours, or days. Its value
must be greater than zero.
Time Unit
Indicates the units in which ewmaMmMovingTimePeriod and
ewmaMmGranularityPeriod are expressed, for example, seconds, minutes,
hours, or days. An implementation may restrict the value of this object to
seconds only.
Thold Error1
This attribute contains an error threshold level associated with the Estimate
Of Mean. It must be initialized before the object is unlocked and may later be
modified if the object has been locked.
Thold Clear1
Contains a clear threshold level which is compared against Estimate Of Mean.
It must be initialized before the object is unlocked and may later be modified
after the object has been locked.
Thold Action1
Specifies the action or actions to be taken when ewmaEstimateOfMean passes
either Thold Error1 or Thold Clear1.
Observed Object
The object identifier of the object to which this monitor instance is applied. It
consists of the object identifier that specifies the object’s type, followed by
components specifying the object’s instance.
Threshold Pair States
The current clear/error states of a monitor’s two threshold pairs. The default
value is clear1Clear2(1).
Unlock Error
An error detected when the monitor was unlocked.
