All Linux lovers, and supporters of open source code and free software, in the Kanto area (or anywhere else) are invited to attend the next Tokyo Linux Users Group meeting. Membership is open to anyone. There are currently no membership dues or entrance fees.

TLUG meetings are traditionally small and unstructured (VERY CASUAL). Most of the benefit of the meeting comes from chatting with other Linux users and having informal discussions.

As a general rule, the Technical Meetings are held on the 2nd Saturday of odd-numbered months and the Nomikai Meetings are usually held on the 2nd Friday of even-numbered months. There are, of course, exceptions to this rule, so it is best to keep an eye on the mailing list, or check back here for date/venue changes as the date approaches.

"Nagira - Nagios RESTful API" by Dmytro Kovalov

Nagira is open source project for development of web services API for popular monitoring system Nagios.

RESTful API allows remote access to read configuration data and object status database of Nagios. Using same HTTP(S) protocol Nagira also allows to submit passive check results for hosts and service checks. In future versions planned also to be able to change Nagios configuration and control Nagios server.

Using webservices API would allow:

  • Distributed monitoring using multiple Nagios instances and integrating

services information in single dashboard;

  • Service checks aggregation from single or multiple Nagios instance into

composite check(s)

  • Modular monitoring setups for applications with RESTful API's
