Alarm Configuration

4.To select the Variable to be used for your alarm, use the MIBTree panel provided on the right side of the window. (For more information about how to use the MIBTree panel, see the MIB Tools chapter in the Tools Guide.) The display will default to the top of the tree (labeled Internet); there are three ways to locate and/or assign the correct variable:

a.If you know the exact name of the OID whose value you wish to track,

simply enter the name in the Alarm Variable field; to verify that you have

entered the name correctly, click on to move the MIBTree display to that OID. (If the MIBTree display does not adjust to show the OID you’ve entered, you’ve entered the name incorrectly.)

b.Use the Radar View panel located just left of the MIB Tree panel to adjust the MIB Tree display to the part of the tree that contains the variable you are interested in, then click to open the appropriate folders. (Again, see the Tools Guide for more details on using the Radar View.)

c.Use the scroll bars and click to open the appropriate folders in the MIBTree panel to locate the object you wish you use; click to select it in the panel, and its name will automatically be entered in the Alarm Variable field.

If you don’t know the exact spelling of the OID you wish to use for your alarm variable,

TIP and you can’t find it by searching through the tree, use the MIBTree utility’s Find feature to locate the OID and determine its exact spelling (and tree location). For more information on the MIBTree panel and its Find capabilities, see Chapter 3, MIB Tools, in the SPECTRUM Element Manager Tools Guide. Note that this Find feature is no longer case-sensitive.

Almost any RMON or MIB-II object can be used as an alarm variable as long as it is resident in the device firmware and its value is defined as an integer (including counters, timeticks, and gauges). If you select an invalid object (i.e., one whose value is not an integer), the message “!!Can’t set alarm on this type!!” will display in the Alarm Variable field.

NOTE

If you select an object which is not resident in the device firmware, you will receive a “Set Failed; ensure variable is readable” message when you try to set your alarm by clicking on . If you are unsure just which objects are resident on your device, and you find yourself receiving a lot of “Set Failed” messages, you can use the MIB Tools utility (accessed from the primary window menu bar or from the Module View) to determine which objects are and are not part of your device’s firmware — simply query the object you are interested in; if the query response comes back empty, the object is not present (make sure you are using the appropriate community name when making a query, or you will get no response).

5.Once you have selected the object you wish to use for your alarm variable, you must assign the appropriate instance value in the Alarm Instance field. Most RMON objects are instanced by the index number assigned to the table in which they reside; for example, if you wish to set an alarm on an object
