Using the Monitor - Proxy Services
Proxy Services displays present detailed proxy server performance metrics for the cluster. Use the Proxy Services displays to quickly identify overloaded proxy services and locate the extend client connection causing the issue.

Proxy Services performance metrics include: CPU%, Requests, Request Average Duration, Request Pending Count, Task Backlog and Active Threads.

NOTE: Click the button to view the current display in a new window.

Proxy/Extend Connections
Table shows proxy services data, including connections, CPU usage and bytes sent and received, and a trend graph displays messages and bytes sent and received for the selected remote endpoint.

The table data is the result of joins of metric from the following Coherence MBeans: Service and ConnectionManager. For details on attributes of these MBeans go to: http://download.oracle.com/otn_hosted_doc/coherence/350/com/tangosol/net/management/Registry.html.
