Presence
Viewing presence status
Presentities 
Status > Applications > Presence > Presentities
This page lists each presentity whose presence information is 
being managed by (i.e. published to) the local Presence Server 
and whose presence information has been requested by a 
subscriber. Presentities are listed here whether or not there is 
any information currently available about that presentity. If a 
presentity has been subscribed to but there is no information 
being published about it, then it will be listed here if the local 
presence server is authoritative for the presentity’s domain. 
Presentities are listed here regardless of whether the subscriber 
that requested the information is registered locally or to a 
remote system.
Note: FindMe users will be listed here if their presence 
information has been requested by a subscriber.
URI: The address of the presentity whose presence information 
has been requested.
Subscriber count: The number of endpoints who have requested 
information about that particular presentity.
To view the list of all subscribers who are requesting information 
about a particular presentity, click on the presentity’s URI. 
Subscribers
Status > Applications > Presence > Subscribers
This page lists each endpoint that has requested information 
about one or more presentities whose information is managed 
by (i.e. published to) the local presence server. Endpoints 
requesting this information are listed here regardless of whether 
they are registered locally or to a remote server.
Note: FindMe users will not be listed here as a FindMe entity 
cannot subscribe to presence information. However, one or more 
of the endpoints that make up a FindMe user may be requesting 
presence information, in which case that endpoint will be listed 
here.
URI: The address of the endpoint that has requested presence 
information.
Subscription count: The number of local presentities about 
whom this endpoint is requesting information.
To view the list of all local presentities whose information is 
being requested by a particular endpoint, click on the endpoint’s 
URI.
Publishers
Status > Applications > Presence > Publishers
This page lists each presentity whose presence information is 
being managed by (i.e. published to) the local Presence Server. 
All Presentities are listed here regardless of whether or not 
anyone is requesting their presence information. If there are no 
Publishers listed, this could mean that the Presence Server is 
not enabled on this VCS.
Note: FindMe users are not listed here as they do not have 
their status individually published. The status of a FindMe 
user is based on the published status of the endpoints and/or 
presentities that make up the FindMe user, and is determined by 
the Presentity Manager.
URI: The address of the presentity whose presence information 
is being published. 
Document count: The number of sources of information that 
are being published for this particular presentity. All endpoints 
that are registered to the VCS will have information published on 
their behalf by the PUA (as long as they are registered with an 
alias in the form of a URI). If an endpoint supports presence, it 
may also publish its own presence information. This means that 
some presentities will have more than one source of information 
about their presence. It is the job of the Presentity Manager to 
aggregate this information and determine the actual status of 
the presentity.
