symon is a system monitor. It can be used to obtain accurate and up to date
information on the performance of a number of systems.

Currently the "suite" consists of these parts:

symon - lightweight system monitor. Can be run with privleges equivalent
    to nobody on the monitored host. Offers no functionality but monitoring
    and forwarding of measured data.

symux - persists data. Incoming symon streams are stored on disk in rrd
    files. symux offers systems statistics as they come in to 3rd party
    clients.

syweb - draws rrdtool pictures of the stored data. syweb is a php script
    that can deal with chrooted apaches. It can show all systems that are
    monitored in one go, or be configured to only show a set of graphs.

sylcd - symux client that drives CrystalFontz and HD44780 lcds. sylcd
    shows current network load on a specific host.

SymuxClient.pm - generic perl symux client. Could, for instance, be used
    to get the hourly amount of data that was transmitted on a particular
    interface.
