Poll a reference variable and perform a calculation
Note: This example is provided as an illustration only and is not supported. Technical support
is available for the Context object, SNMP API, and scripting environment, but Ipswitch does
not provide support for JScript, VBScript, or developing and debugging Active Script
monitors or actions. For assistance with this example or with writing your own scripts, visit
the WhatsUp Gold user community (http://www.whatsupgold.com/wugspace).
This performance monitor polls a reference variable, and then performs an arithmetic
calculation with the returned value.
// This script is a JScript that demonstrates how to use a reference variable in a
script.
// The reference variable "RVsysUpTime" is an SNMP reference variable defined
// 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");
if (RVsysUpTime == null) {
// Pass a non zero error code upon failure with an error message.
// The error message will be logged in the Performance Monitor Error Log
// and in the eventviewer.
Context.SetResult(1, "Failed to poll the reference variable.");
}
else {
// 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:
Context.SetValue(sysUpTimeHours);
