Resource Usage - Cisco TelePresence Administrator's Manual

Overview and status information

Resource usage

The Resource usage page
cumulative license usage for calls and registrations.
It shows current and peak (highest concurrent) usage broken down by:
Unified CM remote session calls (if Unified Communications Mobile and remote access is enabled)
n
Traversal calls
n
Non-traversal calls
n
SIP traversal audio-only calls
n
Registrations
n
TURN relays (VCS Expressway only)
n
It also displays resource and license usage information:
Monitored resource usage, expressed as a percentage of the system capacity.
n
Current and peak license usage, expressed as a percentage of the available licenses for each license type.
n
Each traversal call license allows either 1 video call or 2 audio-only SIP calls. Hence, a 100 traversal call
license would allow, for example, 90 video and 20 SIP audio-only simultaneous calls. Any other audio-only
call (non-traversal, H.323 or interworked) will consume a standard video call license (traversal or non-
traversal as appropriate).
You can view details of current calls or registrations by clicking on the relevant item in the section.
All statistics are based on data since the system was last restarted. The information on this page refreshes
automatically every 5 seconds.
Clustered VCS systems
If the VCS is part of a cluster, details for each peer are shown as well as totals for the entire cluster.
Any traversal or non-traversal call licenses that have been installed on a cluster peer are available for use by
any peer in the cluster. Usage is limited to the maximum physical capacity of each VCS unit:

TURN relays *
* On a Large VM, the total TURN capacity of 6000 relays is spread evenly across 6 ports; each port is limited
to handling 1000 relays. On VCS appliances (or equivalent VM), there is a single TURN port that handles up
to 1800 relays.
Note that each VCS comes pre-installed with 2,500 registration licenses, and that registration and
TURN relay licenses are not shared across a cluster.
If two endpoints are registered to different cluster peers, and a SIP call is made between them, two non-
traversal licenses are used. If the call is made over H.323, only one non-traversal license is used.
