## プロジェクトの歴史と使われ方

ntopng is the next-generation branch of ntop's network traffic monitoring line: a web-based traffic and security monitor built for modern multi-Gbit, application-aware networks rather than the late-1990s assumptions of the original ntop.

### プロジェクトの歴史

ntop's own 2013-05-01 announcement framed ntopng as a restart 15 years after the first ntop release in 1998. The post says the old codebase had become too old, complicated, and bug-prone for newer requirements such as multi-Gbit links, mobile hosts, cloud/decentralized monitoring, and application-protocol visibility.

The same announcement identified core design choices that still explain the package: open source, self-contained, Redis-backed caching, nDPI-centered protocol identification, PF_RING support for high-rate capture, C++ implementation, and a real-time monitoring focus.

### 採用の歴史

ntopng sits in the broader ntop ecosystem with nDPI, PF_RING, nProbe, and related commercial/open-source traffic-analysis tools. Its GitHub repository was created on 2015-04-30 and the project is distributed through Homebrew, Linux packages, and ntop's own installation channels.

Its adoption is strongest with network operators and homelab or appliance users who want a local web UI for interface traffic, flow collection, host/application visibility, and alerting without building a full observability stack from scratch.

### 使われ方

Package users generally run Redis, start `ntopng` against one or more interfaces or flow endpoints, then use the web UI on the configured HTTP port. The upstream docs show use as a flow collector with nProbe, hierarchies of ntopng instances, command-line access to REST/Lua endpoints, separate Redis database IDs for multiple local instances, and virtual interface views that aggregate physical interfaces.

### パッケージ好きにとっての重要性

The package is historically interesting because it is a rewrite born from operational scaling pressure: ntop had the name and user base, but ntopng is where the project adapted to DPI, flow collection, Redis-backed state, and web-first traffic analysis.

### タイムライン

- 1998: first ntop generation, according to ntop's 2013 ntopng announcement.
- 2013-05-01: ntop announced ntopng as a new-generation replacement direction.
- 2015-04-30: GitHub repository created.
