Note: If you wish stop the monitoring of the statistic (usually for a short time), uncheck the Threshold box and select Modify.
Note: You cannot modify the threshold values from this dialog box.
Threshold
Type
Type of Threshold value you are going to specify. Possible values are Max, Min or Equal:
Max - If Collected value exceeds Threshold value, an event will be generated.
Min - If Collected value is less than Threshold value, an event will be generated.
Equal - If Collected value is equal to Threshold value, an event will be generated.
Threshold
Value
Integer value which can be interpreted in two ways:
1. In the case of a Threshold defined for Long values, the data collected for the OID is compared with
this value.
2. In the case of Percentage Thresholds, the result of (first OID / secondOID) * 100, a percentage
value, is compared with this value.
Rearm Value Integer which denotes that when the collected value (or calculated value in case of percentage
thresholds) reaches the Rearm value, the violated Threshold is brought back to normal and a clear
event will be generated.
Reset
Severity
When the Threshold is reset, by what severity it should be denoted.
Allowed
Values
String value which will be compared with the string data collected. If both match then a Threshold
event will be generated. The string which you can specify here can be:
- simply a string, for example router5.
- a comma separated list, for example router1, router2.
- using wild card characters, for example router* where * indicates any number of characters and any
character.
Disallowed
Values
String which will be compared with the string data collected. If both match then a Threshold event will
be generated denoting a reset of Threshold. You can enter strings as specified above.
ObjectID The Object Identifier for which data will be collected in case of PercentageThresholds.For example,
2.2.1.16.1.
Object ID
Type
Type of Data identifier whether it is Node, Interface or Multiple.
Message String that will be displayed in the Event panel of Fault module when Threshold value is exceeded.
Clear
Message
String that will be displayed in the Event panel of Fault module when Threshold is reset (cleared).
Send Clear
Only when this check box is checked, Clear events will be generated on Threshold reset.
Otherwise the Threshold will be reset and you will not know,
as no information will be
displayed in Event panel of Fault module.
