Viewing the diagnostic log

If you are an IBM® DevOps Test Virtualization Control Panel (Test Virtualization Control Panel) administrator, you can view, download, and share the contents of the diagnostic log of Test Virtualization Control Panel. The diagnostic log provides information about the execution of the Test Virtualization components. When enabled for a given proxy, this log records the same information as is contained in the log files that proxy writes to the disk, for example, information about how the HTTP proxy matches requests against the rules it has and whether it sends requests to a stub or to the live system. It might also include information about the execution of Test Virtualization Control Panel itself. You can view the diagnostic log on the server web UI.

Test Virtualization Control Panel is a central point of coordination among agents and proxies when stubs are running. To facilitate identifying and solving problems with Test Integrations and APIs proxies when they occur, the server can display a diagnostic log that is a centralized view of log events of those proxies.

Note:
The HTTP/TCP proxy and the JDBC proxy are the only proxies that can be enabled for remote diagnostic logging to the server. By default, remote diagnostic logging is not enabled for either proxy, so you must enable it.

The diagnostic log can be exported to a comma-separated value (CSV) file, which can be shared with anyone who is not a Test Virtualization Control Panel user but who might be affected by, or be involved in supporting, the server or Test Virtualization.

When the Diagnostic log page is first displayed, the most recent events are displayed first.

  1. Log into the server.
  2. Click the Administration navigation link.

    Alternatively, click the Administration icon on the Home page.

    The Administration page is displayed.

  3. Click the Diagnostic log tab.

    The Diagnostic log tab is displayed.

    The columns on the tab are as follows:
    • Created (Time offset): The time offset indicates the difference between the time that a log message is sent and the time it has received in the server.
    • Source: The source type and hostname are displayed, if available. If the source type and hostname are not available, the universally unique identifier (UUID) of the source is displayed.
    • Logger: Activity log messages are displayed in the diagnostic log and are indicated by Activity Log under Logger
    • Message
    • Trace Data

    The following table describes how to use the controls on the tab:
