Introduction

AVMon is a peer-to-peer (p2p) overlay designed to monitor the availability of the hosts in the system, intended to be used by large-scale distributed applications. AVMon is self-organizing, and its design deals with selfish and colluding hosts that might want to (mis-)report higher than real availability.

The code is published as a C library under the LGPL.

Download

Version 0.4.3 is available in our sourceforge.net download page.

AVMON's code is managed with Git, probably the most popular distributed source code version control system. Development code can be browsed at AVMON's Git repository. Alternatively, you can clone our repository with the following command:

git clone git://avmon.git.sourceforge.net/gitroot/avmon

Development Status

AVMON is currently Beta software and under heavy development. The API and protocol can change at any time, and bugs are squashed regularly. There are many features to implement before we can call it v1.0, and some of them are in the TODOpage. As always, patches are welcome.

Nevertheles, AVMON is mature enough to be used to deploy your own availability monitoring overlay.
