Resource Usage - Cisco TelePresence Administrator's Manual

Resource usage

The Resource usage page
current and cumulative calls (traversal and non-traversal) and registrations on the VCS:
Current: the number of calls or registrations on the VCS at this particular moment.
n
Peak: the highest number of concurrent calls or registrations handled by the VCS since it was last
n
restarted.
Since last restart: the total number of calls or registrations handled by the VCS since it was last restarted.
n
License limit: the total number of licenses available on the VCS.
n
To view details of current calls or registrations, click on the relevant item in the section. Note that if your
system is a VCS Expressway, TURN relay license information is also displayed.
This information refreshes automatically every 5 seconds.
Clustered VCS systems
If the VCS is part of a cluster, then details for each peer are shown as well as totals for the entire cluster.
From software version X7, 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. (Prior to X7, licenses were not shared across the cluster;
each peer could only use the licenses that were loaded onto it.)
The number of licenses that can be installed on any one individual peer is limited to the maximum capacity of
each VCS unit, as follows:
500 non-traversal calls
n
100 traversal calls
n
2,500 registrations
n
Note that each VCS comes pre-installed with 2,500 registration licenses, and that registration 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.
If a cluster peer becomes unavailable, the shareable licenses installed on that peer will remain available to
the rest of the cluster peers for two weeks from the time the cluster lost contact with the peer. This will
maintain the overall license capacity of the cluster — however, note that each peer is still limited by its
physical capacity as listed above. After this two week period, the licenses associated with the unavailable
peer are removed from the cluster. To maintain the same capacity for your cluster, you should ensure that
either the problem with the peer is resolved or new option keys are installed on another peer in the cluster.
