You use Weblogic monitors to check metrics of your Weblogic servers.

Requirements

  • You must copy the wlclient.jar library to the <ReadyAPI installation directory>\bin\ext folder. You can find it in the <WebLogic installation>\Oracle\Middleware\wlserver_10.x\server\lib folder.

  • The user account used to connect to the server should be a member of the Monitor or Admin group.

  • IIOP (Internet Inter-ORB Protocol) must be enabled on the server.

For detailed information, see Preparing Servers for Monitoring.

Monitor Settings

To create a monitor for your Weblogic server, set the following values:

  • Port – The port used to communicate with the server.

  • User name – The user account LoadUI uses to connect to the server.

  • Password – The password used to connect to the server.

Frequently Used Metrics

The Weblogic monitor provides information about the load created by users on the application server. LoadUI displays the following statistics in charts by default:

  • VM Memory – Heap Memory Used – The current amount of memory used by the virtual machine. The large amount of used memory indicates heavy load or memory leaks.

  • VM Threading – Thread Count – The number of threads created on the virtual machine. Monitor this metric to get information about the number of created threads.

  • JVM – HeapFreeCurrent – The current amount of memory available to the JVM heap. The free memory space is affected by the amount of garbage the Java machine has and the amount of memory it uses to handle requests. If this value is low, you may need to allocate additional memory to the Weblogic server.

Here are some other frequently used metrics:

  • Thread – QueueLength – Monitors the number of queued requests on the server. If the queue appears on the web server, it means that the server does not handle the load. In most cases, you want no queue on your soak or peak tests. During a spike test, a lengthy queue is acceptable as long as it is eventually handled by the server.

  • JRockit – TotalGarbageCollectionTime – The garbage collector process has the highest priority in the system. If your machine spends a lot of time collecting garbage, it has fewer resources to work with incoming requests. Try to keep this value as low as possible.

  • JRockit – AllProcessorsAverageLoad – The average load on the processors generated by the server. Monitor this metric and compare it with the metrics of Unix or Windows monitors if your server has the 100% CPU load. If the returned value takes a large percent of total, the Weblogic server is causing issues. If not, search for another reason for the heavy CPU load.

Other Metrics

LoadUI can access runtime MBeans of the Weblogic server. The provided counters may vary depending on the server version. You can find a full list on MBeans in the Servers: Monitoring section of the Weblogic server documentation. Below is a typical example of the metrics that you get in LoadUI. Note: You can click the category to see the description of metrics in MSDN.
