Metrics
Depending on sensor type, different metrics and KPIs are reported. Directionality and granularity is also depending on the test type and test configuration. This article outline the reported metrics per test type for all sensors –
Cisco Provider Connectivity Assurance Sensor Control (formerly Skylight sensor: control) , Cisco Provider Connectivity Assurance Sensor Agents (formerly Skylight sensor: agents), and Cisco Provider Connectivity Assurance Sensor Capture (formerly Skylight sensor: capture)
Synthetic measurements (active)
Terminology
Measurement Sessions
A measurement session is a stream of packets sent from a sending endpoint to one or several receiving endpoints. Some streams are reflected back to the origin using reflectors, in this mode of operation the sender is referred to as the source and the refector the target. Other sessions consist of client / server response mechanisms, such as an HTTP GET (web page retreival) where the initiator of the request is the source and the web service is the target. The measurement packets have a wide variety of encodings, including IPv4, IEEE802, TWAMP, etc. A test session can be either a continous test, like 24/7 ping - or a single-run test such as a TCP throughput test.
Measurement sessions types and directions
• One-way (OW) is a unidirectional measurement stream where metrics are measured on a path from a source to a destination (direction SD). A one-way session may also be multicast, from one sender to a group of receivers.
• Two-way (TW) is a bi-directional measurement stream between a sender and a reflector where metrics are measured separately on both paths, i.e., the source to destination (SD) path, and the return path from a reflector and back called the destination to source (DS) path.
• Round Trip (RT) is a bi-directional measurement stream between sender and a reflector (or service like a HTTP server) where metrics are recorded for the full source-destination-source path. In a round-trip measurement, you cannot distinguish between the SD and DS directions.
Note that some session types may report a combination of round-trip and two-way metrics.
Metric Classification
There are several efforts in standardizing metrics, including IETF RFCs and ITU-T. IETF classifies metrics into 'singleton', 'sample', and 'statistical', where singletons are individual instances of a measurement (e.g. the one-way delay of one packet) and samples are a collection of singletons (such as a vector of one-way delay metrics). Statistical metrics are derived from the more primitive values, such as the average of the one-way delay metric over some time interval.
The major part of the metrics in this article fall into the 'statistical' class. Note, though, that some 'higher level' statistical metrics are derived from other statistical metrics. For example, the quality metrics, including MOS and R-value, is computed by a composition of loss and latency together with static codec impairment parameters.
While most statistical metrics are computed immediately at the time of the sampling by the sender/receiver, many of the higher level metrics could be computed off-line, such as by a server or a presentation client.
Continous session metrics report
For continous session types, where the sender never stops transmitting its test packets or streams, a function to periodically report the measurements is leveraged. At every report interval the sender / receiver will collect and calculate KPIs for the last interval into a metrics report which is sent upstream towards Cisco Provider Connectivity Assurance (formerly Skylight performance analytics).
The metrics set depends on the session type but typically contains metrics such as max, min, percentiles based on the raw measured metrics.
The metrics reports are numbered (statRound) and timestamped (statTime) and mechanisms are in place to retransmit lost reports if connectivity towards Cisco Provider Connectivity Assurance is down temporarily.
Percentiles
A percentile is a statistical value that represents a distribution of result data. When calculating a percentile, the complete set of data collected during an interval is stored in a list that is sorted in ascending order. A specific percentile may then be retrieved from the sorted list by reading the corresponding element in the list. In this way percentile 0 (min) is equal to the first value (smallest) in the sorted list, percentile 100 is the last value (largest) in the list, and the median (percentile 50) is the value at the middle of the list.
Example, if there are 1000 measured delay values during a report interval; the 99th delay percentile will then represent the 10th highest delay value. I.e the max value after 1% largest values have been discarded. This is useful to filter out spikes and short-lived anomalities that may otherwise disturb any analytics done on the metrics set. Percentiles are abbreviated with a 'p'. The 25th percentile is termed p25, etc.
Metric types for synthetic measurements
Time domain metrics
Time metrics are related to latency, that is, the passing of time between the sending of a packet and its reception or between sending a request towards a service and getting a response.
Counted metrics
Count metrics holds information about number packets received and metrics derived from packet sequence numbering such as loss, reorders and duplicates.
Packet field metrics
These metrics are derived form fields in the received ethernet or IP headers, such as DSCP or TTL values.
Quality metrics
A quality metric is higher level metric derived from one or many metrics to form customer experience measure. Examples include MOS score and TCP efficiency.

Capture-based metrics (passive)
Terminology
Metric or Field
This is the reported statistic, which could be a specific protocol field like "response.status" for the HTTP return code, a metadata type identifier as "client.zone.name" which ties the reported metric to a group of clients in a zone – or a more generic QoE metric like "server.rt" denoting the service / server response time in milliseconds.
Layers
This column indicates in which protocol layer each metric is available. Some metrics are specific for only one protocol, and others are common across many or all supported protocol parsers.
