Though a bit off-topic I ran in to this project at the CascadeIT
conference. I'm currently in corp IT that is Notes/Windows based so I
haven't had a good place to test it but the concept is very interesting.
They distributed way they monitor would greatly reduce bandwidth overhead.
http://assimproj.org
The Assimilation Project is designed to discover and monitor
infrastructure, services, and dependencies on a network of potentially
unlimited size, without significant growth in centralized resources. The
work of discovery and monitoring is delegated uniformly in tiny pieces to
the various machines in a network-aware topology - minimizing network
overhead and being naturally geographically sensitive.
The two main ideas are:
- distribute discovery throughout the network, doing most discovery
locally
- distribute the monitoring as broadly as possible in a network-aware
fashion.
- use autoconfiguration and zero-network-footprint discovery techniques
to monitor most resources automatically. during the initial installation
and during ongoing system addition and maintenance.
