Network performance monitoring
There are different and varied network connection monitoring tools, but I prefer those that can be managed via the console. This allows for flexibility and, at the same time, can be used to run test batteries to verify the information that’s been received.
The first tool we’ll look at is basic but also has enough power to generate a quick analysis of the connection’s behavior.
nmon
Nigel’s Monitor (nmon) was created for the IBM AIX operating system with release 4.3 in 2006 and was ported to Linux in 2015 under the GNU General Public License for use.
nmon is a benchmark tool. It collects operating system statistics, including the following:
- CPU (and CPU thread utilization or CPU frequency)
- GPU stats
- Memory use (physical and virtual, swap and paging)
- Disk (read and write, transfers plus service time and wait times, groups)
- Network (read and write and transfers), and more
