Perfmon-like for Linux?

Question

In windows there is perfmon to monitor various performances aspects (called counters) of the system.

Is there a perfmon-like for Linux?

Answer 1

The program "top" does most of this. It does not handle network traffic though.

Edit:

If you need to log this information for post processing/analysis you can use the standard package "sar" to do this. It supports MANY different performance numbers including: disk, cpu, memory, network, etc.
