Port Gauges
In Flexible Resource Capacity mode, the Port Gauges in the Status Bar show the numbers as
they appear in the resource report.
MCU Resource Management by RealPresence Resource Manager (XMA),
Polycom CMA and Polycom DMA
When the RealPresence Resource Manager (XMA), Polycom CMA and Polycom DMA are
part of the solution, following a request by the RealPresence Resource Manager (XMA),
Polycom CMA or Polycom DMA, the MCU will send updates on resource usage to both
CMA and DMA, with each application updating its own resource usage for the MCU. This
provides better management of the Collaboration Server resources by the RealPresence
Resource Manager (XMA), Polycom CMA and Polycom DMA.
Guidelines
• Following requests sent by CMA and DMA, the Collaboration Server will send the
number of occupied resources for a conference or total for the MCU.
• Occupied resources are resources that are connected to ongoing conferences.
Disconnected endpoints in an ongoing conference are not counted as occupied
resources.
• The Collaboration Server is unaware of the resource usage split between the CMA and
DMA.
Port Usage Threshold
The Collaboration Server can be set to alert the administrator to potential port capacity
shortages. A capacity usage threshold can be set as a percentage of the total number of
licensed ports in the system.
When the threshold is exceeded, a System Alert is generated.
The default port capacity usage threshold is 80%.
The administrator can monitor the MCU’s port capacity usage via the Port Gauge in the
Status Bar of the Collaboration Server Web Client.
Free The number of MCU resources available for connecting AVC and
SVC-based endpoints.
Total The Total column displays the total number of resources of that type
(Occupied and Free).
