Client Sessions

This report provides information about active and finished multicast sessions in a form similar to the Unicast sessions report. The difference lies in the set of displayed parameters that are more relevant for the analysis of multicast sessions.

Description of the table parameters:

Parameter	Description
Session quality	Average session quality ratio (%). Meaning of the session quality
Min session quality	Minimum session quality ratio (%). Meaning of the session quality
Mode	Session type: L — live TV stream; VOD — VoD content; STANDBY — the session is in the standby mode; OTHER — the subscriber device is authorized in the system, but the content has not been launched yet.
UID	Unique identifier of an end-user device within the SmartTUBE SDP
Reported IP	IP sent by the end-user device with the KEEP ALIVE event
Hardware ID	End-user device identifier used for internal API requests and other SmartLabs applications
Device type	Type of the end-user device. See How Device Type is Defined.
SAN	Service account identifier unique across the SmartTUBE platform
Start date	Session start time (on the subscriber device, UTC)
Duration	Session duration (s)
State	Current session status (Active or Finished)
Channel	Name and ID of the channel being viewed. Note: the channel name is requested by its ID in the corresponding SmartTUBE dictionary.
Content	Program or movie title
CPU count	Number of events on abnormal CPU usage of subscriber device during the session.
Mem count	Number of events on abnormal memory usage of subscriber device during the session.
Buffering events	Number of completed stream buffering events on the subscriber device.

Device info

This panel provides general information about the end-user device:

Parameter	Description
UID	Unique ID of the subscriber device (UID).
Hardware ID	End-user device identifier used for internal API requests and other SmartLabs applications
Device type	Type of the subscriber device, STB model.
SAN	Subscriber account ID on the SmartTUBE SDP platform at the moment of the last verified session.
Location	Location of the subscriber device in the operator network, determined at the moment of authorization.
App version	Client application version of the subscriber device in the last verified session.
Firmware version	Firmware version of the end-user device
Reported IP	IP sent by the end-user device with the KEEP ALIVE event
Quality	Average session quality ratio (%)
Session type	Type of the last verified session (unicast or multicast)

Verified session — a session with low quality and/or duration of more than a minute.

Unverified session — a session with good quality and duration less than a minute (the subscriber switched to the channel, but did not watch it not because of quality problems, but in search of the desired content). Information on such a session is deleted from DB.
