Scalable, Python‑based monitoring framework compatible with Nagios
Shinken delivers a flexible, Python‑driven monitoring solution that mirrors Nagios configuration while scaling to large infrastructures across Windows, Linux, and FreeBSD.

Shinken is a Python‑written monitoring framework that speaks the same configuration language as Nagios. It targets teams that already have Nagios setups or need a monitoring system that can grow with their infrastructure, from a handful of hosts to thousands.
The platform retains full compatibility with existing Nagios plugins and config files, eliminating migration friction. Its modular, Python‑centric architecture lets you write custom checks or extend core functionality with ease. Shinken runs on any OS supporting Python—including Windows, GNU/Linux, and FreeBSD—using standard init.d scripts for service management. Configuration resides in /etc/shinken, logs in /var/log/shinken, and debug mode can be activated via /etc/init.d/shinken -d start. The framework is released under AGPL‑3.0 and is designed for environments that demand cross‑platform support and horizontal scalability.
When teams consider Shinken, these hosted platforms usually appear on the same shortlist.

Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
Migrate existing Nagios setup to a scalable architecture
Retain all current host/service definitions while gaining modular scaling and Python extensibility.
Monitor mixed Windows and Linux data center
Deploy Shinken agents across both OS families, centralizing alerts in a single system.
Implement custom health checks for proprietary services
Write Python plugins to probe internal APIs, integrating results with standard alerting.
Scale monitoring for a rapidly expanding cloud environment
Add new hosts without reconfiguring core, leveraging Shinken’s distributed scheduler.
No. Shinken reads standard Nagios config files and plugins unchanged.
Any platform with a Python interpreter, including Windows, GNU/Linux, and FreeBSD.
Start the daemon with the `-d` flag (`/etc/init.d/shinken -d start`) and review logs in `/var/log/shinken`.
Shinken is released under AGPL‑3.0, which requires source distribution of modifications when deployed over a network.
Installation creates init.d scripts; use `chkconfig` or `update-rc.d` to enable at boot.
