svrThrAlarmType
Module: SVRMGT-MIB
OID (symbolic): SVRMGT-MIB::svrThrAlarmType
OID (numeric): 1.3.6.1.4.1.36.2.18.22.2.2.3.1.5
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Is this a greater than, greater than or equal to, equal to, less than or equal to, or less than alarm?
Greater Than or Greater Than or Equal To thresholds for absolute values occur when the sample value exceeds (or equals) the svrThrThresholdValue and svrThrAlarmState was reset. This will cause the svrThrAlarmState to be set and, if svrAlarmEnableTraps is true, a svrThrExceptTrap will be sent. SvrThrAlarmState will be reset when the sample value falls below or equals svrThrResetValue. For delta values, the same holds true except the difference between the sample value and the svrThrLastValue is used for comparison with both the svrThrThresholdValue and the svrThrResetValue.
Less Than or Less Than or Equal To thresholds for absolute values occur when the sample value falls below (or equals) the svrThrThresholdValue and svrThrAlarmState was reset. This will cause the svrThrAlarmState to be set and, if svrAlarmEnableTraps is true, a svrThrExceptTrap will be sent. SvrThrAlarmState will be reset when the sample value exceeds or equals svrThrResetValue. For delta values, the same holds true except the difference between the sample value and the svrThrLastValue is used for comparison with both the svrThrThresholdValue and the svrThrResetValue.
Equal To thresholds for absolute values occur when the sample value equals svrThrThresholdValue and svrThrAlarmState was reset. This will cause the svrThrAlarmState to be set and, if svrAlarmEnableTraps is true, a svrThrExceptTrap will be sent. SvrThrAlarmState will be reset when the sample value does not equal svrThrResetValue. For delta values, the same holds true except the difference between the sample value and the svrThrLastValue is used for comparison with both the svrThrThresholdValue and the svrThrResetValue.
NOTE - It is possible to have negative delta values since the differ- ence is computed as the current value minus the svrThrLastValue.
The default value on row creation is greaterThan.
What is svrThrAlarmType?
This read-write value (default greaterThan(1)) picks the comparison used to trigger this threshold's alarm: greaterThan(1), greaterThanOrEqualTo(2), equalTo(3), lessThanOrEqualTo(4), or lessThan(5), compared against svrThrThresholdValue and cleared against svrThrResetValue. An admin sets lessThan(5) to alarm when a metric like free disk space drops below a critical value, with the reset value providing hysteresis to avoid trap flapping.
Examples
Walk all instances (SNMPv2c):
