The performance tool can be used to display performance information about the transaction service. This information is gathered using the Performance JMX bean, so the transaction service needs to be integrated into an application server, such as JBoss Application Server, to give any performance information. The performance information is displayed via a multi-series graph. To view this graph, open a performance window by selecting Performance+Open. The multi-series graph displays a number of items. The items can be turned on or off from the Series menu. When series are enabled, they appear in the legend at the bottom of the graph. Number of transactions. Number of committed transactions. Number of aborted transactions. Number of nested transactions. Number of heuristics raised. The data shown is graphed against time. The Y-axis represents the number of transactions and the X-axis represents time. You can stop and restart the sampling of data at any time using the Sampling menu. You can save the data currently visible in the graph to a Comma Separate Values (CSV) file from the Data+Save to .csv option.
