Description of QoE metrics

Netflow

Metric Description Values
Octet delta Traffic difference (bytes) at the beginning and end of the specified period
Fragmented packets delta Difference of IP packets divided into parts/fragments at the beginning and at the end of the specified period
RTT Round-trip time is the time taken to send the signal plus the time it takes to confirm that the signal has been received.
This round-trip time therefore consists of the time it takes to transmit a signal between two points within a single flow.
All network activity within a source/destination socket (source IP:port /destination IP:port) is taken as a flow in DPI
Source AS AS host number
Destination AS Subscriber's AS number
Post nat source IPv4-address An IP address converted from private to public by NAT to communicate with external devices and access the Internet
Post nat source port A port converted by NAT from private to public for communicating with external devices and accessing the Internet
Vchannel/Bridge Vchannel — vChannel number.
Bridge — number of the bridge through which the traffic goes
Service class Traffic classes cs0 — cs7. For more details see Traffic distribution by class for the tariff plan 0 — cs0
1 — cs1

7 — cs7
Receiver IP-interface index and Sender IP-interface index Traffic direction 1 — to whom traffic is directed;
2 — where the traffic comes from.
Example:
The first option is outbound traffic;
The second option is inbound traffic.

Clickstream

All Clickstream metrics are defined for HTTP traffic only.
Metrics for HTTPS traffic cannot be defined because it is encrypted.
Metric Description Values
Path The address to which the subscriber went
Referer The resource from which the request came.
Used for redirection: the address from which the user went to the redirection page is memorized
User agent Allows you to understand from which device the request was made
Method Server request method 0 — undefined
1 — GET
2 — POST
3 — PUT
4 — DELETE
Result code The HTTP code that the server returned 200 — ОК
403 — Forbidden
Content length How many bytes of information the server returned in response to the request
Content type Content-Type in HTTP, used to define the MIME type of a resource
Locked Bitmask, contains an indication that the resource has been blocked or redirected 0x3 for HTTP
0x1 for the rest
Host type 1 for HTTP
2 — CNAME
3 — SNI
4 — QUIC

DNS Flow

Metric Description
Host DNS host domain name from the DNS response
Host category Category of the involved host, determined automatically
Total Number of records from the raw log, grouped into a single entry in the aggregated log
Sessions Number of internet sessions of the subscriber in the aggregated log
Hosts Number of hosts in the aggregated log
Host categories Number of host categories in the aggregated log
DNS hosts IPs Number of unique IP addresses of DNS hosts
Logins Number of logins in the aggregated log
Subscribers Number of subscribers in the aggregated log
Channels Number of vChannels in the aggregated log
Time Time of session start
Session ID Session ID
Login Subscriber login
Source IPv4-address Information about the source of the request. The source can be either a subscriber or a host
Source IPv6-address
Source port
Destination IPv4-address Information about the recipient of the request. The recipient can be either a subscriber or a host
Destination IPv6-address
Destination port
DNS transport Protocol used for transmitting DNS requests
DNS host IP DNS host domain name from the DNS response
DNS host port IP address of the DNS host
Subscriber Port used by the DNS host
Subscriber port IP address of the subscriber
Rrclass Port used by the subscriber
DNS type Resource class (RR Class) in the DNS request
TTL Indicates the function of the server in processing and storing DNS requests in the domain name system:

1 - A
5 - CNAME
DNS data The acceptable time for storing this resource record in the cache of a non-responsive DNS server
VLAN ID RDATA encoded in base64. For example, it is possible to find out which IPs belong to the host
Post VLAN ID Unique identifier of the virtual local area network
DPI ID VLAN ID after route change
Vchannel/Bridge Number of DPI, taken from GUI: Administrator → Equipment
MPLS labels Channel — number of vChannel.
Bridge — number of the bridge through which traffic flows
Labels for routing packets in MPLS networks
