symon

Performance and information monitoring tool

The symon project consists of three parts; a data monitor, a data consolidator and a data displayer. symon is a is a lightweight system monitor that measures cpu, memory, pf, interface and disk statistics every 5 seconds. It sends this data on to symux for further processing. symon has been designed to inflict minimal performance and security impact -- it can be run as nobody on the system it monitors. symux is a non-privileged daemon that listens to incoming symon traffic. symux can write the incoming symon streams into rrd files. Clients interested in monitoring machine state can also log into symux and receive data as ascii as it arrives.
