Welcome to SUMON (Simple Unix MONitoring) home page!
SUMON is a tool for gathering relevant statistics and other
information about a set of Unix systems.
It stores data from agents in a central server, and shows them in a convenient
web interface. Once installed, you can sit down and see how your boxes are performing
from one single point.
SUMON is intended for on-line monitoring and capacity planing, as it may store data
for years.
At present time, supported architectures are Linux (several distros tested), and AIX.
You can download it from Sourceforge SUMON's page
