Using System Manager to monitor the system

You can use the InterChange Server Component Management view in System Manager to monitor the IBM WebSphere Business Integration Server Express system and to get informational messages for all component status changes in the system. You also can start, stop, pause, and shut down InterChange Server Express components and change component properties from this view. For instructions on starting, stopping, and pausing components or on changing component properties, see Administering components of the system.

The following section describes how to work in System Manager to connect to an InterChange Server Express instance and to view component statistics from the InterChange Server Component Management view. To use the InterChange Server Component Management view in System Manager, you must first connect to an InterChange Server Express instance.

Steps for connecting to an InterChange Server Express instance

Perform the following steps to connect to an InterChange Server Express instance.

  1. Open System Manager.
  2. In the InterChange Server Component Management view, right-click the InterChange Server Express instance to which you want to connect, and click Connect on the pop-up menu (see Figure 16).
    Note:
    You must register the default server first. For Windows and Linux, the default server is WebSphereICS and for OS/400 and i5/OS, the default server is QWBIDFT44.
    Figure 16. Connect to InterChange Server Express
  3. Enter the following information in the Login dialog box that appears:

    When a connection is made, the light on the InterChange Server Express instance icon changes from red to green, and any objects that have been deployed to that server appear in folders beneath the server (see Figure 17).

Viewing and using statistics

You can monitor statistics for the InterChange Server Express environment in the InterChange Server Component Management view to help you better manage the system. Statistics can be viewed for InterChange Server Express, collaboration objects, and connectors.

By watching and becoming familiar with your system's normal operating statistics, when problems occur, you can use the monitors to identify and isolate problems, and pinpoint problems in flow processing.

Monitoring your system's statistics can help you to optimally configure your system's resources. The statistics windows show currently configured parameters and provide graphs that track resources during flow processing. You can easily see if your system resources are used efficiently or if they need to be adjusted. The following procedures describe how to use the Server Statistics window, the Collaboration Object Statistics window, and the Connector Statistics window:

Note:
Before you can see any system statistics, System Manager must be connected to an InterChange Server Express instance. For instructions on connecting to an InterChange Server Express instance, see Steps for connecting to an InterChange Server Express instance.

Steps for viewing server statistics

Perform the following steps to check InterChange Server Express statistics:

  1. Open System Manager and go to the InterChange Server Component Management view.
  2. Right-click the InterChange Server Express instance and click Statistics.

    The server statistics appear (see Figure 18).

    Figure 18. Statistics window for InterChange Server Express
  3. Under Database Connections you can view the following information:

    The Database connections area shows statistics for:

    Cache max configured
    The maximum number of connections configured. This is the value the attribute MAX_CONNECTIONS. If this attribute is not configured, it displays Default.
    Cache in use
    The current number of connections used from the connection cache.
    Cache peak
    The maximum number of connections used by the server from its connection cache since the server was booted.

    The area below the cache statistics lists the system and dynamic connection pools. The system pools are REPOSITORY, EVENTS_MANAGEMENT, FLOW_MONITORING, USER_REGISTRY and TRANSACTIONS. The dynamic pool is the Relationship pool. The following details for each of these pools are maintained:

    Free
    The current number of available connections in the connection pool.
    In use
    The current number of connections used by this connection pool.
    Max Configured
    The maximum number of connections configured. This is the value in the InterchangeSystem.cfg file for the attribute MAX_CONNECTIONS in the respective subsections of the different connection pools (Event Management, Transactions, Repository). If this attribute is not configured, it displays Default.
    Peak
    The highest number of connections used by the server from this pool since the server was booted.
  4. Under Depth of Message Queues, you can view a list of all the subscription queues in the configured queue manager. The following statistics are displayed:
    Queue Name
    The name of the subscription queue.
    Current
    The number of messages currently in the queue. This does not include subscriptions messages that are in the work-in-progress (WIP) queue.
    Max Configured
    The maximum number of physical messages that can exist on the queue.

Steps for viewing collaboration object statistics

Perform the following steps to check collaboration object statistics:

  1. Open System Manager and go to the InterChange Server Component Management view.
  2. Expand the Collaboration Objects folder.
  3. Right-click the collaboration object for which you want to view statistics and click Statistics.

    The statistics for that collaboration object appear (see Figure 19).

    Figure 19. Statistics window for collaboration objects

    Note:
    Statistics for a collaboration group, as a whole, are not maintained. Each collaboration member in a collaboration group maintains its own statistics. The statistics among group members may differ.
  4. Check the Failed flows statistic for an increase in the normal failure rate. A failure can be caused by several situations, including the unavailability of a connector, corrupt data, and so forth. This number should be kept as low as possible, because some user intervention is needed to resubmit the failures. This count is retained when the collaboration is paused, and it is reset when the collaboration is stopped.
  5. To view general statistics, do the following in the top section of the statistics window:
  6. Under Flow Status, you can do the following:
  7. Under Flow Control, you can do the following:
  8. At the bottom of the statistics window, you can do the following:

Steps for viewing connector statistics

Perform the following steps to check connector statistics:

  1. Open System Manager and go to the InterChange Server Component Management view.
  2. Expand the Connectors folder.
  3. Right-click the connector for which you want to view statistics and click Statistics.

    The statistics for that connector appear (see Figure 20). The window for provides information about the running connector: the connector's application, when the connector was started, how long it has been running, the number of business objects it has received and sent, and flow control information.

    Figure 20. Statistics for connectors
  4. Under Time, you can view the start time of the connector and how long is has been running.
  5. Under Business Objects, you can view the total number of business objects received and sent during the time the connector has been running.
  6. Under Business Objects Sent and Received, you can view the names of the business objects that the connector has sent and received. If the number of business objects sent does not match the number received, some business objects might not have been processed completely.
  7. Under Subscriptions, you can view a list of subscriptions the collaboration subscribes to and the business object name and verb for that subscription. Check the list of subscriptions to verify that the names of the collaborations and initiators are all present and that they are supposed to be there.
  8. Under Flow Control, you can view the number of buffered events and the number of events pending in the database. Two configurable Flow Control properties are listed: Max Event Capacity and Blocked Status. Use this section to monitor the flow control of the connector and to determine if you need to reconfigure the flow control properties of the connector. For instructions on reconfiguring flow control properties, see Steps for configuring flow control for connectors.
