Bumper car driver teaches you to use Nmon to analyze system performance under Linux

Download Nmon.

Depending on the type of CPU you choose to download the appropriate version:
Http://nmon.sourceforge.net/pmwiki.php?n=Site.Download
wget http://sourceforge.net/projects/nmon/files/download/nmon_x86_12a.zip/download

I'm going to get you a package.

Nmon analyser--free tool for generating AIX performance reports: http://down.51cto.com/data/2316753

Initializes the Nmon tool.

#unzip Nmon_x86_12a.zip
Archive:nmon_x86_12a.zip

inflating:nmon_x86_ubuntu810
Inflating:nmon_x86_fedora10
Inflating:nmon_x86_opensuse10

Based on different platforms, initialize the Nmon tool for the corresponding platform:
chmod +x NMON_X86_64_CENTOS6
MV Nmon_x86_64_centos6/usr/local/bin/nmon

For Debian also do the following (do not do the same can be run):
Apt-get Install Lsb-release
lsb_release-d | Sed ' s/description:/t//' >/etc/debian_release

Then run the Nmon directly.

Collect data and generate reports:
Data acquisition:
./nmon_x86_64_centos6-s10-c60-f-m/usr/local/

Parameter explanation:
The-S10 collects data every 10 seconds.
-c60 collected 60 times, that is, the acquisition of 10 minutes of data.
-F generates a data file name that contains the time when the file was created.
The storage directory of the data files generated by-M.

This generates a Nmon file and updates every 10 seconds until 10 minutes later.
The generated file name is: Hostname_090824_1306.nmon, "hostname" is the host name of this host.

To generate a report:
Download Nmon Analyser (free tool for generating performance reports):
Http://www.ibm.com/developerworks/wikis/display/Wikiptype/nmonanalyser

Upload 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 to select the Nmon file, which will generate a parsed result file: Hostname_090824_1306.nmon.xls, open the generated file with Excel to see the results 。

If the macro does not run, the following actions are required:
Tools, macro-and security, and then open the file and allow the macro to run.

Automatically collect data by day:
Add a record to the crontab:
0 0 * * * root nmon-s300-c288-f-m/home/>/dev/null 2>&1

300*288=86400 seconds, just a day's data.
