In Policy Enforcement Manager™ (PEM), you can gather report on subscriber video traffic consumption across different devices (phone, tablet, PC or TV). This information helps to analyze user quality of experience (QoE).
After a PEM and QoE profile is enabled on a virtual, the QoE module detects video flows and gathers data. When the QoE data is passed to PEM, a subscriber QoE report is generated based on the corresponding policy settings. The reports can be sent over syslog (HSL) or IPFIX.
In an enforcement policy, a rule can send QoE-based information about traffic that matches certain criteria to an external high-speed logging (HSL) server. The logs include the following comma-separated values in the order listed.
|Report id||Identifies the reporting module (PEM) and the field value is 23003143.|

|Source IP||The IPv4 source address in the IP packet header.|
|Source Transport Port||The source (L4) port.|
|Destination IP||The IPv4 destination address in the IP packet header.|
|Destination Transport Port||The IPv4 destination address in the IP packet header.|
|Protocol Identifier||The IP Protocol field.|
|Media Type||Different types of media, for example, MP4.|
|URL X SessionId||The ID used to associate different segments of a whole video or audio.|
|Width Height||The resolution of the video.|
|Bit Rate||The number of bits that are conveyed or processed per unit of time.|
|Frame Rate||The frequency (rate) at which an imaging device produces unique consecutive images called frames.|
|Duration||The length of time of the media.|
|Watched||It is the length of time that the video has been watched.|
