Status Page

Valuemation Web provides the 'VM Status Info' servlet which displays essential information about the internal status of Valuemation Web running on this server. No special authentication is required for this page to be displayed.

By default, the formatted HTML table is available. The unformatted JSON response can be also configured so that you can embed it in the existing applications.

The Status Page can display the following data:

• VMWeb Servlet

  Shows if the 'vmweb' is running.

• VMWeb average response time in the last 5 mins (ms)

  Shows the average response times (in ms) of requests on this server in the last 5 minutes.

• VMWeb average response time in the last 15 mins (ms)

  Shows the average response times (in ms) of requests on this server in the last 15 minutes.

• Memory consumption - allocated / free (*) / max. (MB)

  The 3 values have the following meaning:

  • allocated memory = latest allocated memory of the JVM (minimum heap size <= allocated memory <= maximum heap size)

  • max = the maximum Heap size to which the JVM can grow (allocate memory)
• Threads count

  Displays the number of threads running in the servlet.
