How can I find out how much of a load my webserver is under? I tried top
but I don't know how to interpret the information it's showing me for CPU. While top may give me the CPU usage I also need to find out the bandwidth (load on the NIC) to see if the server is being overwhelmed or not. I tried netstat
but all I could see is what the active connections are.
I don't know much about serve maintenance, I'm a programmer and my sysadmin is on jury duty. Any hints are much appreciated.
I'm running Apache on Ubuntu server, with a few small PHP scripts. The majority of the traffic is some large binary files which are being downloaded.
