I have had a bunch of Linux based streaming servers that employed lighttpd web server to provide video streaming via port 80.

Recently, our service is very slow. Therefore, I would like to ask if there is a good software package that helps us monitor and record our bandwidth usage, lighttpd established connections, TCP sync connections, disk I/O ... over time.

Any suggestions?

Cacti - for graphing historic data

Hyperic - clunky, but has good auto discovery and integration via is agent

Zenoss - open source competitor to Hyperic

Munin - UNIX Style monitoring toolkit, similar to Cacti, in the spirit of MRTG

Collectd - Another stats collection daemon, you'll need to integrate it with something else to produce your statistics.
