Viewing accounting and statistics data in the web user interface

The Flow comparison view displays statistical information relating to all message flows in the selected resource, and you can use this information to see where you might enhance performance in terms of resource usage, message flow throughput, and response times. When you have identified a message flow that requires attention, you can use the Flow analysis view to see more detailed statistical information about the nodes in the flow.

• The Throughput per message flow section shows statistics relating to the throughput of messages in all message flows in the selected integration node, integration server, application, or library, during the last 20-second reporting period. The following information is provided for each message flow:
  • The number of messages per second processed by each message flow (the message rate)
  • The average elapsed time (in milliseconds) per message in the message flow
  • The average CPU time (in milliseconds)
  • The total number of messages processed by each message flow
  • The number of active threads in the message flow
  • The number of backouts processed by the message flow
  • The immediate parent of the resource (for example, the application that contains the message flow)

  You can sort the information in the table based on any one of these statistics by clicking the header of the required column.

  If you select a message flow in this table, the nodes contained by the flow are highlighted in the Nodes for all flows section.

  A Go to Flow analysis view icon (a magnifying glass) is displayed next to each message flow in the table. You can click this icon to display the Flow analysis view, which contains detailed statistics for each node in the selected message flow.

• The Nodes for all flows section shows statistical information about all the message flow nodes in the running message flows that have statistics collection turned on, for the selected integration node, integration server, application, or library. Nodes for message flows that have statistics turned off are not shown in this table. The following information is provided for each node in the message flows:
  • The average CPU time (in milliseconds) for the message transactions in the node
  • The average elapsed time (in milliseconds) for the message transactions in the node
  • The total elapsed time (in milliseconds) for the message transactions in the node
  • The total CPU time (in milliseconds) for the message transactions in the node
  • The number of times that the node has been invoked
  • The type of node
  • The parent message flow for the node

  You can sort the information in the table based on any one of these statistics by clicking the header of the required column. If you select a node in this table, its parent flow is highlighted in the Throughput per message flow section.

• The charts in this view show data for three statistics at a time. By default the charts show the message rate, average elapsed time, and average CPU time for the selected message flow; however, you can select any three statistics to display in the charts by clicking the arrow in the table next to each graph and then selecting the required statistic from the list. The tables show the highest, lowest, and average data for the whole of the current browser session, and the data for the latest 20-second reporting period.
• The Latest data per node section shows statistical data for each node in the selected message flow, including the elapsed and CPU time per message processed by the node. You can choose to display the minimum, average, or maximum CPU and elapsed times per message, by clicking Minimum, Average, or Maximum in the section heading. You can also sort the data in the table by clicking on the heading of a column; for example, you can sort the data by CPU time by clicking the heading CPU time (ms).

  This table also shows the type of each node, which can help you to identify the potential cause of any performance problems; for more information, see Identifying the cause of a slow message flow.

• The Flow profile section shows a graphical representation of the selected message flow, displaying all nodes in the flow.
