This article shows you how to use NMON to analyze system performance under Linux, the content is concise and easy to understand, it can definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Download the version of the appropriate CPU type:

Use the corresponding operating system file:

Mv nmon_x86_ubuntu810 / usr/local/bin/nmon

You also need to do the following for Debian (you can also run it if you don't have to):

: i%uD.gO0apt-get install lsb-releaseITPUB personal space 9I2jTR8\-_ d

Lsb_release-d | sed 's/Description:\ tUniverse / etc/debian_release

Then run nmon directly.

Collect data and generate reports: ITPUB personal space CPV&M?,@_+i/t

Data collection: ITPUB personal space 1g Universe vI3Dr

Parameter explanation: ITPUB personal space\ ipersonal space; | `8q&D#xN

-S10 collects data every 10 seconds. ITPUB personal space P`rt $M1P

-c60 collects 60 times, that is, the data is collected for ten minutes. ITPUB personal Space ~ & RF8 | Ften G) o xd%PY/Y

-f the data file name generated contains the time when the file was created. ITPUB personal Space x]? s "QTIX J H [Q

-m the directory where the generated data files are stored.

A nmon file is generated and updated every ten seconds until ten minutes later.

4Oi7XD y}-L1X0 generates a file name such as: hostname_090824_1306.nmon, and "hostname" is the hostname of this host.

Download nmon analyser (a free tool for generating performance reports): ITPUB personal space FP,pQ "e0l&mW

Http://www.ibm.com/developerworks/wikis/display/Wikiptype/nmonanalyser

Transfer the previously generated nmon data file to the Windows machine and open the analysis tool nmon analyser v33C.xls with Excel. Click the "Analyze nmon data" button in the Excel file and select the nmon data file, which will generate an analyzed result file: hostname_090824_1306.nmon.xls. Open the generated file with Excel and you can see the result.

If the macro cannot be run, you need to do the following: ITPUB personal space C ^} uz'wI4O? I

Tools-> Macro-> Security->, then open the file and allow the macro to run.

Automatically collect data on a daily basis:

300 seconds, 288 seconds, 86400 seconds, which happens to be a day's data.
