// This script is a JScript that demonstrates how to use a reference variable in a script.

// with an OID of 1.3.6.1.2.1.1.3 and instance of 0.
// Poll reference variable RVsysUpTime
var RVsysUpTime = Context.GetReferenceVariable("RVsysUpTime");

// The error message will be logged in the Performance Monitor Error Log
// and in the eventviewer.

// Success, use the polled value to convert sysUpTime in hours.
// sysUpTime is an SNMP timestamp which is in hundredths of seconds:
var sysUpTimeHours = RVsysUpTime / 3600 / 100;
// Save the final value to graph:
