STATUS current
DESCRIPTION
"This data type indicates the validity and sign of the data
in associated object instances which represent the absolute
value of a high capacity numeric quantity. Such an object
may be represented with one or more object instances. An
object of type HcValueStatus MUST be defined within the same
structure as the object(s) representing the high capacity
absolute value.
If the associated object instance(s) representing the high
capacity absolute value could not be accessed during the
sampling interval, and is therefore invalid, then the
associated HcValueStatus object will contain the value
'valueNotAvailable(1)'.
If the associated object instance(s) representing the high
capacity absolute value are valid and actual value of the
sample is greater than or equal to zero, then the associated
HcValueStatus object will contain the value
'valuePositive(2)'.
If the associated object instance(s) representing the high
capacity absolute value are valid and the actual value of
the sample is less than zero, then the associated
HcValueStatus object will contain the value
'valueNegative(3)'. The associated absolute value should be
multiplied by -1 to obtain the true sample value."

hcAlarmInterval OBJECT-TYPE
SYNTAX Integer32 (1..2147483647)
UNITS "seconds"
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The interval in seconds over which the data is sampled and
compared with the rising and falling thresholds. When
setting this variable, care should be taken in the case of
deltaValue sampling - the interval should be set short
enough that the sampled variable is very unlikely to
increase or decrease by more than 2^63 - 1 during a single
sampling interval.
This object may not be modified if the associated
hcAlarmStatus object is equal to active(1)."
::= { hcAlarmEntry 2 }
hcAlarmVariable OBJECT-TYPE
SYNTAX VariablePointer
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The object identifier of the particular variable to be
sampled. Only variables that resolve to an ASN.1 primitive
type of INTEGER (INTEGER, Integer32, Counter32, Counter64,
Gauge, or TimeTicks) may be sampled.
Because SNMP access control is articulated entirely in terms
of the contents of MIB views, no access control mechanism
exists that can restrict the value of this object to
identify only those objects that exist in a particular MIB
view. Because there is thus no acceptable means of
restricting the read access that could be obtained through
the alarm mechanism, the probe must only grant write access
to this object in those views that have read access to all
objects on the probe.
This object may not be modified if the associated
hcAlarmStatus object is equal to active(1)."
::= { hcAlarmEntry 3 }
hcAlarmSampleType OBJECT-TYPE
SYNTAX INTEGER {
absoluteValue(1),
deltaValue(2)
}
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The method of sampling the selected variable and
calculating the value to be compared against the thresholds.
If the value of this object is absoluteValue(1), the value
of the selected variable will be compared directly with the
thresholds at the end of the sampling interval. If the
value of this object is deltaValue(2), the value of the
selected variable at the last sample will be subtracted from
the current value, and the difference compared with the
thresholds.
If the associated hcAlarmVariable instance could not be
obtained at the previous sample interval, then a delta
sample is not possible, and the value of the associated
hcAlarmValueStatus object for this interval will be
valueNotAvailable(1).
This object may not be modified if the associated
hcAlarmStatus object is equal to active(1)."
::= { hcAlarmEntry 4 }
hcAlarmAbsValue OBJECT-TYPE
SYNTAX CounterBasedGauge64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The absolute value (i.e., unsigned value) of the
hcAlarmVariable statistic during the last sampling period.
The value during the current sampling period is not made
available until the period is completed.
To obtain the true value for this sampling interval, the
associated instance of hcAlarmValueStatus must be checked,
and the value of this object adjusted as necessary.
If the MIB instance could not be accessed during the
sampling interval, then this object will have a value of
zero and the associated instance of hcAlarmValueStatus will
be set to 'valueNotAvailable(1)'."

DESCRIPTION
"The alarm that may be sent when this entry is first set to
active. If the first sample after this entry becomes active
is greater than or equal to the rising threshold and this
object is equal to risingAlarm(1) or
risingOrFallingAlarm(3), then a single rising alarm will be
generated. If the first sample after this entry becomes
valid is less than or equal to the falling threshold and
this object is equal to fallingAlarm(2) or

generated.
This object may not be modified if the associated
hcAlarmStatus object is equal to active(1)."

hcAlarmRisingThreshAbsValueLo OBJECT-TYPE
SYNTAX Unsigned32
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The lower 32 bits of the absolute value for threshold for
the sampled statistic. The actual threshold value is
determined by the associated instances of the
hcAlarmRisingThreshAbsValueHi and
hcAlarmRisingThresholdValStatus objects, as follows:
ABS(threshold) = hcAlarmRisingThreshAbsValueLo +
(hcAlarmRisingThreshAbsValueHi * 2^^32)
The absolute value of the threshold is adjusted as required,
as described in the HcValueStatus textual convention. These
three object instances are conceptually combined to
represent the rising threshold for this entry.
When the current sampled value is greater than or equal to
this threshold, and the value at the last sampling interval
was less than this threshold, a single event will be
generated. A single event will also be generated if the
first sample after this entry becomes valid is greater than
or equal to this threshold and the associated
hcAlarmStartupAlarm is equal to risingAlarm(1) or
risingOrFallingAlarm(3).
After a rising event is generated, another such event will
not be generated until the sampled value falls below this
threshold and reaches the threshold identified by the
hcAlarmFallingThreshAbsValueLo,
hcAlarmFallingThreshAbsValueHi, and
hcAlarmFallingThresholdValStatus objects.
This object may not be modified if the associated
hcAlarmStatus object is equal to active(1)."

DESCRIPTION
"The upper 32 bits of the absolute value for threshold for
