It was written initially for AIX to monitor system performance. nmon for Linux can be used to collect informations on CPU, memory, network, disk I\/O, top processes etc.<\/p>\n

System administrator can use nmon as a tuner or benchmark tool that will provide performance information in one go.<\/p>\n

It can output the data on the screen or can be save the data into a comma separated file for analysis and longer term data capture.<\/p>\n

\nm – See memory stats.
\nd – See disk stats.
\nk – See kernel stats.
\nn – See network stats.
\nN – See NFS stats.
