Advanced Alarm Configuration3-17Alarm ConfigurationIf you wish to modify an existing alarm, enter the appropriate index value,or double-click on the alarm of interest in the Alarms Watch list (in the mainAlarm/Event window).4. To select the Variable to be used for your alarm, use the MIBTree panelprovided on the right side of the window. (For more information about how touse the MIB Tree panel, see the MIB Tools chapter in theTools Guide.) Thedisplay will default to the top of the tree (labeled Internet); there are threeways 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 haveentered the name correctly, click on the Find-> button to move the MIBTree display to that OID. (If the MIB Tree display does not adjust to showthe 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 adjustthe MIB Tree display to the part of the tree that contains the variable youare interested in, then click to open the appropriate folders. (Again, seetheTools 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 to use; click to select it in thepanel, and its name will automatically be entered in the Alarm Variablefield.Almost any RMON or MIB-II object can be used as an alarm variable as longas 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 thistype!!” will display in the Alarm Variable field.NOTEClicking on the Index button to select the next available index number will replace thecurrent Owner string with the default value described above; if the default value isalready in place, the date and time will be updated.TIPRemember, the only thing that determines whether you are modifying an existing alarm orcreating a new one is the assignment of the index number; be sure to assign this valueappropriately.TIPIf you don’t know the exact spelling of the OID you wish to use for your alarm variable,and you can’t find it by searching through the tree, use the MIB Tool Find feature to locatethe OID and determine its exact spelling (and tree location). For more information on theMIB Tool utility and its Find capabilities, see the MIB Tools chapter in the SPECTRUMElement Manager Tools Guide. Note that this Find feature is not case-sensitive.
