CISCO-HC-ALARM-MIB file content
The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.
Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

Such an object may be represented with one or more object instances. An object of type CHcValueStatus 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 CHcValueStatus 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 CHcValueStatus 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 CHcValueStatus object will contain the value 'valueNegative(3)'. The associated absolute value should be multiplied by -1 to obtain the true sample value."

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 cHcAlarmStatus object is equal to active(1)." ::= { cHcAlarmEntry 2 } cHcAlarmVariable 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 cHcAlarmStatus object is equal to active(1)." ::= { cHcAlarmEntry 3 } cHcAlarmSampleType 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 cHcAlarmVariable instance could not be obtained at the previous sample interval, then a delta sample is not possible, and the value of the associated cHcAlarmValueStatus object for this interval will be valueNotAvailable(1). This object may not be modified if the associated cHcAlarmStatus object is equal to active(1)." ::= { cHcAlarmEntry 4 } cHcAlarmAbsValue OBJECT-TYPE SYNTAX CounterBasedGauge64 MAX-ACCESS read-only STATUS current DESCRIPTION "The absolute value (i.e. unsigned value) of the cHcAlarmVariable 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 cHcAlarmValueStatus 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 cHcAlarmValueStatus will be set to 'valueNotAvailable(1)'." ::= { cHcAlarmEntry 5 } cHcAlarmValueStatus OBJECT-TYPE SYNTAX CHcValueStatus MAX-ACCESS read-only STATUS current DESCRIPTION "This object indicates the validity and sign of the data for the cHcAlarmAbsValue object, as described in the CHcValueStatus textual convention." ::= { cHcAlarmEntry 6 } cHcAlarmStartupAlarm OBJECT-TYPE SYNTAX INTEGER { risingAlarm(1), fallingAlarm(2), risingOrFallingAlarm(3) } MAX-ACCESS read-create STATUS current DESCRIPTION "The alarm that may be sent when this entry is first set to active.

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 cHcAlarmStartupAlarm is equal to risingAlarm(1) or risingOrFallingAlarm(3).
