Network flow analyzer2/15/2024 ![]() sFlow, short for “sampled flow”, is an industry-standard for packet export at Layer 2 of the OSI model. ![]() org Consortium, this protocol is supported by a wide range of network devices, as well as routing software and network solutions. SFlow (6343 port) is a protocol designed for monitoring network, wireless and host devices. It processes the most common types of Flow: NetFlow, sFlow, J-Flow, IPFIX, NetStream. It receives, analyzes, and processes all traffic transiting the network and transfers data in a compatible mode to NFA Databases – MySQL and ClickHouse. The collector is one of NFA’s most important components. It offers a comprehensive set of reports, graphs and flows information that can reflect the current and historical state of a network. Broker is used for communication between the NFA components.įrontend represents a complex browser application that interacts with NFAAPId. NFAalertd is used to detect and generate alerts based on the alert settings set by the end-user. NFAaggd periodically aggregates flow data that is stored in the database and flushes data according to the configuration parameters. NFApushd is used to send notifications and alerts to the end-users. NFABGPd stores and keeps all routes and adds AS Path to traffic flow. The token is passed as a query parameter for all API requests that require authentication. NFA API uses an authentication mechanism based on authentication tokens. Access NFA’s frontend to manage users or configure external User Directories. A valid NFA user-id is required to access most of the API services. ![]() NFAAPId represents a set of secure web services that collect data from Databases. Collector (NFAflowd) receives, analyzes, and processes all traffic transiting a network.ĭatabases NFA uses two databases: MySQL (configuration) and ClickHouse (Data Mart), that act relating to the central repository which stores processing results.
