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 ReadyAPI 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. ReadyAPI 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
ReadyAPI Performance can access the runtime metrics of applications running on the WildFly server. Below is an example of typical metrics you will get:
| Category | Description | Metrics |
|---|---|---|
| Application Sessions | Information about application sessions on the server. |
Active Sessions Expired Sessions Max Active Sessions Rejected Sessions Session Avg Alive Time Session Max Alive Time Created Sessions |

Current Thread Count Active Thread Count Largest Thread Count Queue Size Task Count Completed Task Count Rejected Task Count |
| EJB3 | Information about Enterprise Java Beans (EJB) 3.0. |
Execution Time Invocation Count Peak Concurrent Invocation Count Pool Current Size Pool Max Size Pool Available Count Pool Created Count Pool Removed Count |
| Data Source Connections | Information about connections to data sources. |
Available Count Active Count Created Count Destroyed Count In Use Count Max Used Count Waiting Request Count Max Waiting Request Count Max Waiting Time |
| Data Source Caches | Information about cached data sources. |

| Transactions | Information about transactions executed by the server. |
Aborted Count Application Rollback Count Committed Count Heuristic Count Inflight Count Nested Count Resource Rollback Count Timed Out Count Transaction Count |
| JMS Queues | Information about JMS queues that are used to balance the load. |
Consumer Count Delivering Count Message Count Added Message Count Scheduled Message Count |
| JMS Topics | Information about JMS topics where messages are published. |
