Use of Linux monitoring Nmon and analyser

Test pressure when using a simple Linux monitoring tool Nmon, not only real-time monitoring, can also generate files with icon style display, small and practical

Installing Nmon

Nmon is actually a tarball directly extracted to the directory to be placed, and then directly run it can

#tar-ZXVF nmon_linux_14i.tar.gz-c/data/program

#./nmon_x86_64_centos6

Note that if you don't want to write as complicated as you do, you can use alias to simplify

Run

real-time monitoring , direct input C (CPU) m (memory) after operation, can be directly H (Help) view

Chart detection

#nmon-ft-s 10-c 20 (Run once per 10s, run 20 times, can be customized)

#ps Aux|grep Nmon (see if run ends, generate Localhost_150707_1103.nmon file after end)

Pass the Localhost_150707_1103.nmon file through SecureCRT's SZ command to Windows

#sz Localhost_150707_1103.nmon

If you do not have the SZ command, install #yum installation lrzsz-y and execute the above command, the transferred files can be located in the option/session to view the path

Chart analysis

Open Nmon Analyser V34a.xls, set macro security, direct point to the Analyze button, the chart will be automatically generated

PS: Here I have a problem nmon analyser "Runtime error 62, input beyond the end of file", my workaround is to replace the analyser version

Final results

(the picture didn't pass)
