Device List
The Device info section provides you with a detailed information about a particular end-user device and its activity at the moment and in the past. The search is performed by UID or CSI (Client session ID).
Search by UID
The UID, a unique device identifier, is generated in different ways depending on the type of a device:
- Linux based STB — unique MAC address of the STB;
- Android STB — unique serial number of the device;
- Android mobile application — unique deviceID of the device;
- iOS mobile application — unique UID automatically generated at the moment of the app installation/re-installation;
- Smart TV — unique UID automatically generated at the moment of the app installation/re-installation;
- Web application — unique UID automatically generated at the moment of the app installation/re-installation (stored in the web-browser cookie). If the cookie has been deleted, the UID will be regenerated.

Device Info
This area provides you with a general information about the end-user device.

Parameter |
Description |
Data source (collection.field) |
UID |
Unique ID of the subscriber device (UID). |
Depending on the session type, two collections can be referenced:
|
Device type |
Type of the subscriber device, STB model. |
clUser.dt |
SAN |
Subscriber account ID on the SmartTUBE SDP platform at the moment of the last verified session. |
clUser.lastState.ch.san |
Location |
Location of the subscriber device in the operator network, determined at the moment of authorization. |
clEvent.type = 12 → clEvent.data.locationId |
User agent |
Content of the User-agent header in the HTTP requests of the client application to the streaming server. Note: data is requested from the last stored unicast session. |
ngSession.httpUserAgent |
App version |
Client application version of the subscriber device in the last verified session. |
clUser.lastState.ch.ver |
IP address |
IP address of the subscriber device. |
Depending on the session type, two collections can be referenced:
|
Last event time |
Time of the last event on the subscriber device in the verified session. |
clUser.lastState.ch.eDate |
Type |
Type of the last verified session (unicast or multicast) |
|
State |
Current state of the last verified session (active or finished) |
clUser.lastState.ch.active |

clUser.lastState.ch.csi |
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 in the clSession collection is deleted (to save space).

Threshold memory
The memory and CPU utilization exceeded one of the following thresholds on the STB:
- Memory Normal Level (default threshold – 60%)
- Memory Critical Level (default threshold – 75%)
- Memory Blocker Level (default threshold – 80%)
- CPU Critical Level (default threshold – 80%)
The default STB behavior when these thresholds are exceeded is as follows:
- Memory Normal Level exceeded — the CPU monitoring timer or reboot timer resets to 60 and 5 seconds respectively.
- Memory Critical Level exceeded — in standby mode, the reboot timer starts; in the other mode, the reboot timer starts when the STB goes into standby mode.
- Memory Blocker Level exceeded — in standby mode, the STB reboots immediately; in other mode, the STB reboots immediately when the CPU utilization level exceeds CPU Critical Level.
This event is sent at intervals specified by parameter memThresholdCheckInterval in the configuration file setup.json of SmartTUBE app.

Memory & CPU Usage Area
Here you can see the diagram of CPU and memory usage of the end-user device.

Parameter |
Description |
Data source (collection.field) |
Realtime average CPU usage, % |
Average CPU usage of a subscriber device in a minute, %. Only for STB. |
clSession.acu |
Realtime average memory usage, % |
Average memory usage of a subscriber device in a minute, %. Only for STB. |
clSession.amu |
Algorithm for generating messages on the abnormal CPU and memory usage:
- Every 5 minutes, the client application measures the end-user device resources usage and stores the result in its memory.
- If there are changes in comparison with the previous result with exceeding the set thresholds — 20% for CPU and 10% for memory, the subscriber device generates a message for SmartCARE.
Sessions List Area
This area provides the following reports:
- Multicast — information about active and finished multicast sessions. See the description of this report here;
- Unicast — information about active and finished multicast sessions. See the description of this report here;
- Authorizations — information about successful and failed authorizations;
- System — information about sessions during which the content was not played.

Search by CSI
CSI is a unique identifier of the client session generated by the end-user device and passed to the SmartCARE with API calls. It represents a string containing the UID, device type and time on the device, separated by the “#” character and converted to hex.
A new CSI is generated under the following conditions:
- Start of New Content Unit: When a new content unit (a channel or movie) begins playback.
- Completion of Rewind: Following the user’s completion of rewinding.
- Resume after Pause: When playback is resumed after a pause.
- Initiation of New Program: When a user initiates the playback of a new program.
- Playback Position Change: If the user selects to play a program from a different position, utilizing options “Play from the Beginning” or “Play from Saved Position” when switching on a live stream.
- Playback Resumption from Standby: When playback is reactivated after the system has been in standby mode.
Please note that if playback stops and subsequently resumes for any reason, this is not classified as a new session, and a new CSI will not be generated in such instances.

Search by the client session ID (CSI)
Entering the CSI and pressing the Show button displays a page with detailed information on the client session, which includes areas described below.
Session Overview Area
This area provides a basic information about the client session.

Clicking on the Down button opens areas with detailed information about the client session.

Quality Indicators Area
These indicators show the ratio of the received data volume and the number of events on the subscriber device by bitrate.

Parameter |
Description |
Data source (collection.field) |
Numbers around circles |
Stream bitrate value (byte/s) — specified in the corresponding SmartTUBE SDP dictionary. The value “-1” indicates the impossibility of determining the bitrate (it was not possible to extract the bitrate value from the URL of the content request came to Collector from the streaming server). |
ngSession.stat.bytesSentByBitrate.<bitrate value> If only one bitrate is used in the system, it can be specified in the Collector-nginx component configuration file by the collector-nginx.services.nginx.bitrate parameter. |
Traffic grouped by bitrates |
The ratio of the data amount received by the subscriber device at different bitrates. |
ngSession.stat.bytesSentByBitrate |

Device Info Area
This area provides general information about the end-user device. See the parameter description here.

Playback Events Area
This area shows events related to the content playback during the selected session.

Exploring the graph and bars under it you can see an additional statistic parameters came with the following events:
Freeze
This event allows you to distinguish between three states in which streaming delay or image freezing occur:
- Pre-buffering — buffering before starting a channel or movie;
- Waiting for data by the HTMLMediaElement
- Buffer underrun — the moment the buffer is zeroed, i.e. there is no content left in the buffer.
