Monitor proxies and DVM

Follow this procedure if you need to troubleshoot or get a more detailed view of the current status and operations of the proxy and the DVM for a selected session.

In addition to viewing summary statistics about the dispatcher and proxies in the monitor page, you may also need to view more detailed statistics about a session.

This level of detail is provided by the Detailed monitoring… tool. You will find links to this in the Monitoring for UA proxies and Monitoring for GWS proxies sections.

  1. Open the monitor page.
    For example, on your machine enter this URL in your browser: http://localhost:6394/monitor.
  2. Select the Detailed monitoring… link for the proxy and session you wish to monitor.

    The page (http://localhost:6394/monitor/session_id) opens in a browser tab. Details are shown for the proxy, the environment, and the applications running in the session.

    Use Table 1 as a reference to help you with analysis of the session data.
