This article is about how to use Nmon performance monitoring tool in Linux. I think it is very practical, so I share it with you. I hope you can get something after reading this article. Let's take a look at it.

I. install the software

# create the directory structure of the nmon tool

[root@nishuangyi /] # mkdir / usr/tools/nmon

Upload installation package

# upload the downloaded package to / usr/tools/nmon through the rz command

[root@nishuangyi /] # cd / usr/tools/nmon/

[root@nishuangyi nmon] # rz

Rz waiting to receive.

Upload Zmodem

Nmon16e_mpginc.tar.gz (3.30 MB, 0:10 min = 337.6 KB/sec)

Extract the installation package

# decompress the downloaded nmon package

[root@nishuangyi nmon] # ll

[root@nishuangyi nmon] # tar zxvf nmon16e_mpginc.tar.gz

Delete installation package

# remove the installation package through the rm-f command

[root@nishuangyi nmon] # rm-f nmon16e_mpginc.tar.gz

Reading and writing empowerment

# configure read, writeable and executable permissions for nmon

[root@nishuangyi nmon] # chmod 777 nmon_x86_64_centos7

Rename

# rename

[root@nishuangyi nmon] # mv nmon_x86_64_centos7 nmon

Start nmon

# execute script to start nmon

[root@nishuangyi nmon] #. / nmon

Configure environment variables

# configure environment variables to start nmon in any file

[root@nishuangyi ~] # vi / etc/profile # enter I and do not add the following two lines to the file:

PATH=$PATH:/usr/tools/nmon

Export PATH

# after entering I, the following two lines are not added to the file:

PATH=$PATH:/usr/tools/nmon

Export PATH

# enter wq! Save exit, source / etc/profile effective configuration

[root@nishuangyi ~] # source / etc/profile

# check whether the environment variable is configured successfully

[root@nishuangyi ~] # nmon
