Extended TCP telemetry (Time To Live (TTL), SYN packet size, default TCP window size) Network performance metrics (Round Trip Time (RTT), Server Response Time (SRT), TCP retransmissions, jitter) Volumetric statistics (bytes, packets, flows) 2 Network Telemetry InformationĮxported network telemetry provides information across all network layers including performance metrics and rich application layer telemetry. However, the content is in sync with the latest LoadMaster LTS firmware. This document has not required substantial changes since 7.2.48.4 LTS. Published with LMOS version 7.2.48.4 LTS.
1.2 Intended AudienceĪnyone who would like to export application flow data from the LoadMaster. The purpose of this document is to describe how to enable this functionality on the LoadMaster and to gain access to the Kemp Flowmon Collector. The purpose of network telemetry is to understand traffic volume and structure at any time, report on key network performance metrics related to application workload and troubleshoot on operation and performance issues with the ability to drill down to individual session level. The network telemetry feature is available on all LoadMaster products with any license or subscription type. Kemp recommends using the Flowmon Collector for this data analysis. The LoadMaster is able to participate in providing flow data visibility in conjunction with a compatible IPFIX data analysis system. Various network devices including switches, firewalls, load balancers, and routers typically provide flow-based feeds to collectors which are then analyzed by a performance monitoring and analytics toolset.įor further details on IPFIX, refer to the following Flowmon page: NetFlow/IPFIX Monitoring. This is often leveraged as an alternative to full packet capture and analysis for ongoing monitoring of a network infrastructure. Flow data provides visibility into application traffic utilization and structure at any time, enabling you to report on key network performance metrics related to application workload. IPFIX is a flow export standard used to identify and collect application and transaction data in a network infrastructure.
As of firmware version 7.2.53 (and Long Term Support (LTS) version 7.2.48.4), the LoadMaster can monitor the network traffic traversing its interfaces and generate rich network telemetry in IP Flow Information Export (IPFIX) format.
