Hzlanr

Hzlanr is a modular software framework designed to monitor, analyze, and visualize performance metrics for local-area networks (LANs). The project focuses on latency, jitter, packet loss, and throughput, providing data collection, processing, and visualization tools to help administrators diagnose congestion and faults. The name hzlanr appears in documentation as an acronym in some contexts, though usage varies and many sources simply treat hzlanr as the project name.

History and governance of hzlanr are diffuse. The initiative emerged in open-source communities during the mid-2010s and has since seen contributions from volunteers across academia and industry. There is no single governing organization; maintainers operate in a distributed fashion, emphasizing openness and interoperability with standard network data formats such as PCAP, NetFlow/IPFIX, and SNMP. Because the project has grown through community involvement, its features and scope have evolved through multiple revisions rather than a single formal roadmap.

Architecture and features of hzlanr are designed to be extensible. Core components typically include data collectors, a processing pipeline, and a visualization layer. The framework supports capturing live traffic, ingesting pre-recorded datasets, and exporting data to formats like CSV and JSON. A plugin system enables new data sources and analysis modules to be added without modifying core code. Alerting rules can trigger notifications based on thresholds for latency, loss, or unusual patterns, aiding rapid diagnosis of network issues.

Implementation and usage vary by deployment. Hzlanr is intended to be portable and multi-platform, with installation through package managers or source builds. Documentation and community support are modest, and users often rely on example dashboards to bootstrap monitoring setups. As a niche tool, hzlanr appeals to small IT teams, researchers, and hobbyists seeking open, LAN-focused visibility.
