Configuring Event Tracing

Events are generated when the client application accesses data and when specific server activities occur, such as when a service starts or an error occurs. Depending on which SequeLink profiles are active, the information generated by the event is displayed as it occurs in the runtime monitor and is stored persistent in the event trace file.

By default, the event trace file is located in the installdir\tracing directory where installdir is your SequeLink Server installation directory.

This information pertains to Windows and UNIX.

On Linux and UNIX, both a monitoring and an event trace profile are enabled when you install SequeLink Server.

NOTE: You can configure only one event trace profile for each SequeLink service.

Creating an Event Trace Profile

  1. Select the Profiles node for a SequeLink service (beneath the service's Configuration node). Select Action / New / Event Trace Profile. The Event Tracing Properties window appears.


    2. The Event Tracing Properties window

  2. Enable and disable events:
    • To enable a group of events, select the check box beside the appropriate group name (Service, Session, Network, Error, Statement, Transaction, or Others).
    • To enable individual events, select the check box beside the event in the scroll box. See "SequeLink® Events" for a list and a description of all events.
    • To disable a group of events, clear the check box beside the appropriate group name (Service, Session, Network, Error, Statement, Transaction, or Others).

      • NOTE: Event names that do not start with Service, Session, Network, Error, Statement, or Transaction are Other events (for example, Cursor Closed).

    • To disable individual events, clear the check box beside the event in the scroll box.
  3. Optionally, you can place a filter on any event or group of events. To add a filter, type the filter in the Filter text box. Some events have a set of attributes. You can place a filter on the attributes of an event. For example, if you want to monitor and trace only authentication events for sessions started by administrators, you could write the following filter for the Session Authenticated event:

    4. ${Authorization} = "administrator"

See "SequeLink® Events" for an explanation of the filter syntax, and a list and description of the attributes for each event.

  1. Click Next. The Add Event Trace Profile window appears. Click Finish in this window to add the profile.
  2. Save the configuration.
  3. Restart the SequeLink service to activate the new event trace profile.
