For WebLogic 8.1 SP6 and WebLogic 9.x monitors, Load Test needs to be started with the -Dsun.lang.ClassLoader.allowArraySyntax=true option. To do that in the command prompt, navigate to the Load Test installation directory and run the following command:

lt -Dsun.lang.ClassLoader.allowArraySyntax=true

    Adding SNMP Agent Monitors

    Load Test can retrieve data based on the provided OID(s) from the SNMP agents of versions 1 and 2c.

    To add an SNMP agent monitor:

    1. Right-click the Monitors node in the Load Test tab and choose New Monitors from the shortcut menu. A New Monitors dialog displays.
    2. Select SNMP from the New Monitors dialog, then click Finish. A configuration panel for the new monitor will open in the right panel.
    3. Type the SNMP agent’s host name in the Host field.
    4. Type the SNMP agent’s community in the Community field.
    5. Enter a parameter by clicking New. The New Parameter dialog opens.



    6. Complete the New Parameter dialog as follows:
      • Parameter Type: Select OID or Composite.
      • Parameter: Depending on the Parameter Type selected, the Parameter options will vary according to the following:
        • OID: Enter the Object ID that identifies a specific parameter within the SNMP agent community. (Only available if OID is selected in the Parameter Type drop-down menu).
        • Composite: Select Processor, Memory, Network, or TCP to collect corresponding data.
        • Counters: Depending on the selection from the Composite parameter drop-down menu, displays CPU Utilization (%), Memory Utilization (%), and Network Utilization (%); these counters are calculated by querying a set of OIDs.
          If TCP is selected from the Composite parameter drop-down menu, you must select a counter from the Counters box.
        • Parameter Explanation: Displays an explanation for the Composite parameter selected.
      • Graph Title: Enter a title for the graph that will correspond to the Monitor you are adding. This title will display in Load Test Progress graphs, and in Detailed Report graphs.
      • Apply operation: Select to apply simple operations to values returned by an SNMP agent. Use  "*" for "multiply", "/" for "divide", and "%" for "percentage of". For example, if the agent returns the value of the allocated memory in bytes but you want to see it in KB, you would apply a "/ 1024" operation by selecting "/" from the drop-down menu and entering "1024" in the adjacent text field. You could then add "Memory in kilobytes" into the Graph Title field.
    7. Repeat the above step until the Parameters table shows all parameters you want this SNMP agent to monitor.
    8. Verify the new monitor by right-clicking the related node in the Load Tests tree’s Monitors> SNMP branch.

    2. Select Windows from the New Monitors dialog, then click Finish.
    3. Type the perfmon’s host name in the Host field.
    4. Enter a parameter by clicking New. The Add performance counter dialog opens.



    5. Complete the New Parameter dialog as follows:
      • Select the performance counter and instance of the parameter you want to monitor. An explanation of the parameter you select displays in the Parameter Explanation box.
      • In the Graph Title field, enter a title for the graph that will correspond to the Monitor you are adding. This title will display in Load Test Progress graphs, and in Detailed Report graphs.
      • In the Apply Operation sub-panel, select an operation and a value to be applied to the monitor data if needed. For example, by selecting the / (divide) operation and entering 1024 in the operation value field, you could convert the original monitor value from Bytes to KBytes.
    6. Repeat the above step until the Parameters table shows all parameters you want this perfmon to monitor.
    7. Verify the new monitor by right-clicking the related node in the Load Tests tree’s Monitors> Windows branch.

    Adding WebSphere Monitors
