Applies to ReadyAPI 3.0, last modified on December 06, 2019

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

Requirements

  • Copy the jboss-cli-client.jar library to the <ReadyAPI installation>\bin\ext installation> folder. You can find it in the <WildFly installation>\bin\client folder.

  • Use the management user account to connect to the server. See WildFly documentation for information about adding users.

Monitor Settings

The monitor has the following settings:

  • 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 WildFly monitor provides information about how users interact with the WildFly server. LoadUI displays the following statistics in charts by default:

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

  • VM Memory – Used – The amount of the virtual machine memory used by the server to process requests. You want this metric below 80% to ensure there is a reserve for more virtual users. If it is too high, add more memory to the machine. It may also require adding more physical memory.

Other Metrics

LoadUI can access the runtime metrics of applications running on the WildFly server. Below is an example of typical metrics you will get:
