For the devices which doesn't have predefined UP TIME counter available (this can happen on less popular devices), it is possible to monitor up time using values from MIB which usually is given by the manufacturer of the device. Of course snmp must be enabled on the device.
- Create new map (or edit existing one) and add data widget - Value and Text is most suitable here.
- After you have added the Widget, edit the properties
- Counter Source should be
Selected node, then select the node which UP time you want to monitor below - Select counter and then click on SNMP Performance counters.
-
Check first option and write OID which shows UP Time, or select it directly from MIB. (if manufacturer provided special MIB which is designed to your device MIB must be compiled before can be selected here)
-
Default MIB to monitor UP time is: "sysUpTime" - it's calculated in hundredths of seconds with TimeTicks base type, select OK -> Next and ADD.
-
Multiplication factor should be "10" (This is because counter is calculated in hundredths of seconds, to see proper data it has to be multiplifacted by 10) Optional: To change name on the widget (which will be full name of MIB - it might be hard to read, switch to Options tab and change Caption to "Up time")
To Check if everything was properly configured, right click on widget and select SNMP View, after data is loaded, compare UP time from SNMP info to Widget.
