  How to monitor Linux system performance Nmon
  Add Date : 2018-11-21      
  Nmon (aka Nigel's Monitor) is a very commonly used system performance monitoring tools, developed by IBM engineer Nigel Griffiths, for AIX and Linux operating systems. This tool can display the current operating system resource utilization directly on the screen to help you identify system bottlenecks and facilitate system tuning. Due to its very well known, in 10 easy to use Linux utilities recommend a simple text has been recommended.

Use Nmon you can easily monitor the system CPU, memory, network, disk, file system, NFS, Top processes and other information.

Installation Nmon

Default Nmon already in Ubuntu's sources, you can use apt-get to install:

sudo apt-get install nmon

Linux system performance monitoring using Nmon

Once the installation is complete, you can start it by executing the nmon command in a terminal.

After Nmon command is executed, you can see the following output:

Nmon command-line tool is a user interaction with the application, you can easily use the keyboard shortcut to view the statistics.

q: Stop and exit Nmon
h: View help information
c: View CPU statistics
m: View memory statistics
d: Check the disk statistics
k: Check Kernel Statistics
n: View network statistics
N: See NFS statistics
j: view the file system statistics
t: Top view process statistics
V: View virtual memory statistics
v: verbose output
Viewing CPU Statistics

If you want to see the CPU performance information, you can directly press c:

Top view process statistics

If you want to see the Top process statistics, you can press the key directly t:

View network statistics

If you want to view network statistics, you can directly press n:

Disk I / O Fig.

Use d key to view the disk statistics:

See Kernel Statistics

If you want to see the kernel statistics, you can press the k button:

Get system information

If you want to view the system information of Linux, such as: system architecture, operating system version, Linux version you can use the r key, which is useful for system administrators.
