    Using dbMonitor
    In This Topic

    To extend monitoring capabilities of dotConnect for BigCommerce applications there is an additional tool called dbMonitor. It is easy-to-use tool to provide visual monitoring of your database applications. dbMonitor can be used for any kind of applications - desktop, ASP.NET and windows services.

    dbMonitor performs per-component tracing of database events such as SQL statement execution, preparing, etc.

    dbMonitor has the following features:

    Description

    1

    Events grid

    Events grid displays you all the traced database events. It provides brief description, timestamp, duration, and event status. Below the grid four windows are docked in the group: SQL, Parameters, Error, and Call Stack. They display information about the event, currently selected in the Events window. You may click the header of the events grid columns to sort the events by the clicked column.

    Event details

    This group of four windows includes:

    • The SQL window displays the SQL statements for the database event, selected in the Events window, if the event is an execution of SQL code.
    • The Parameters window displays the SQL statement parameters for the database event, selected in the Events window, if this event is an execution of SQL statement, containing parameters.
    • The Error window displays information resulted in error.
    • The Call stack window displays call stack of the function, that started the event.
    You can view main details of the selected event, switching between following windows. The screen above shows window for SQL-statement of the event (this event is an execution of SQL code).
    To open a window that you need, select corresponding item from the View menu.

    Processes window

    This window displays list of monitored processes and their status. It allows you to choose what process to trace. Events grid displays events only for the selected process. After process application is closed, it has Terminated status, but its event log is not cleared, you can still view their information or save it to file. To remove terminated process from the list, either right-click it and select Delete Inactive from the popup menu, or click it and then click the Delete Terminated Process button on the toolbar.

    Object tree window

    This window below the Processes window displays monitored objects. Objects are combined in a tree with top level All Objects node, second level connection object nodes, and third level object nodes. Object Tree also contains 'Pools' node to group connection pools. It allows you to view events for all process objects, for specific connection, or for specific object. Just click the node to trace events for this node and its descendants.

    5

    Call tree window

    It contains merged call stacks of the database events for the process. You can use it to filter events by functions, that started them. Just click the function in call stack tree, and Events window will display only events, called from that function or its descendants.

    Remote debugging

    To use remote debugging for your applications, you should set the following properties:

    • BigcommerceMonitor.Host - to the name or IP address of the computer, where dbMonitor will be used.
    • BigcommerceMonitor.Port - to the port, that will be used for communicating between dbMonitor and your application.
    Then in dbMonitor options you should set the same port value on the General tab of the Options Dialog Box. After this you may run your application and monitor database calls.

    Unicode support

    You can monitor applications using international databases by help of the Unicode support.


    During monitoring you can easy switch between client processes and view hierarchy of objects being traced.

    dbMonitor is intended to hamper application being monitored as less as possible.

    Monitoring is accessible at design-time as well.

    To trace your application with dbMonitor you should follow these steps:

    Optional. To trace your application remotely with dbMonitor you should follow these steps:

    Optional. You can further tweak monitoring for better performance:You can improve monitoring performance by disabling call stack sending. Sending a call stack is a costly operation, which can cause performance losses, so if you don't need :
