The CSV File Description includes information about the technologies and standards used in Cisco Provider Connectivity Assurance Sensors (formerly Accedian Skylight performance elements), Provider Connectivity Assurance Sensors F100 and F25 (formerly Accedian Skylight Flex), and Provider Connectivity Assurance Sensor Control (formerly Accedian Skylight sensor: control) equipment.
Moreover, this CSV File Description also applies to the Collection feature of the Legacy Orchestrator (formerly Accedian Skylight Orchestrator), which is a component of the Cisco suite of Provider Connectivity Assurance products. The Collection feature centralizes the collection of performance data from Provider Connectivity Assurance Sensors and transfers the data to a system used to evaluate the data. Collection receives performance data from Provider Connectivity Assurance Sensors in the form of CSV files.
Organization
This CSV File Description includes the following articles:
- CSV File Naming Convention: This article explains the convention used to name CSV files.
- Product Model Information: This article provides information related to the Provider Connectivity suite.
- CSV File Descriptions and Key Performance Indicators (KPI) per Data Category: These articles list the KPI collected for each category of performance data. These articles list the CSV file description table for each of the main categories of performance data. Each CSV file table lists the fields stored in the CSV files and, for each field, provides a detailed description that includes details such as how the value is derived and possible values as well as units of measure and examples. The KPI collected for each of the main types of performance data is also included.
Note: If the field name is also a KPI, it will be indicated in brackets. - Performance Session Metrics: These articles include tables for each of the main categories of performance data. Each table lists the fields stored in the CSV files and, for each field, provides a detailed description that includes details about how the value is derived, units of measure and examples.
