Setting Manual Threshold Alarms

You must first create a trend report for a set of devices and an SNMP MIB Table. Please refer to Saving Long-term Statistics for a description of creating trend reports.

Select the report name in the Trend Selection Tree and use the right-click Properties menu, then use the Instances button.

1.Select one or more rows in the displayed table and click the Add button to add them to the Instances Tree at the left.

2.In the Instances Tree, select one or more labels (including <All Other Instances>) and click the Include or Exclude button.

3.For each included instance, use the Edit button to add alarms for each variable.

4.Select a variable name from the list at the bottom of the Instance Edit dialog.

5.Enter a simple expression at the Threshold edit box. This is an operator (>, <, =, >=, <=, !=) and a numeric constant.

You can also optionally enter a name for this variable instance in the Instance Name edit box. This makes it easier to determine what the threshold alarm refers to.

6.Click OK. You will see a red exclamation mark next to the icon in the Instances Tree for any instances that have manual alarms.

Please keep in mind that for Counter variables, the

values you set in the manual threshold will be compared against a polled sample. The polled sample will be larger or smaller depending on the trend report poll interval. For example, a link that shows 100K bytes in one minute might show 1,000K bytes in 10 minutes. This is different than what you see in trend graph, in which the samples are normalized to per-second values.
