The Application Transactions Layer
This layer will appear only if the eG Java Business Transaction Monitor (BTM) is enabled on the EAP server. To know how to enable Java BTM, refer to Configuring Java Business Transaction Monitoring on JBoss EAP.
Once this is done, then a Java Business Transactions test will appear in this layer. To know how to configure this test and what metrics it reports, refer to the Java Business Transaction Monitoring document.
