Server performance monitoring artifact nmon how to use, in view of this problem, this article describes in detail the corresponding analysis and solutions, hoping to help more partners who want to solve this problem to find a more simple and easy way.

Nmon (Nigel's Monitor) is a tool provided by IBM to monitor AIX system and Linux system resources for free. This tool can collect the resource consumption of the server system and output a specific file, and can use excel analysis tool (nmon analyser) for statistical analysis of the data.

Search and download nmon and upload it to the server for decompression. Let me show you with an older version. After decompression, there are nmon16e_x86_rhel65, and nmon analyser v34a.xls.

Nmon16e_x86_rhel65 is preceded by an executable file, which generates a monitoring file, which contains the collected server hardware metrics with the suffix .nmon.

Nmon analyser v34a.xls is used to convert this monitoring file into an easy-to-read Excel table with charts.

This tool runs automatically in the background after startup, and can collect hardware indicators for a long time. It is suitable for collecting for a period of time, such as a few days, and then summarize and compare the performance scenarios.

Through the analysis of the reasons for the changes in the occupation of hardware resources, there will be a lot of new discoveries to make us master the system more thoroughly.

The command to start nmon is as follows

. / nmon16e_x86_rhel65-f-s 10-c 999999999-m. /

If the failure prompt Permission Denied is executed for the first time, just execute chmod + x nmon16e_x86_rhel65.

Parameter explanation:

-s 10 data is collected every 10 seconds.

-c 999999999 collects hardware data for 999999999 times, indicating that I need to collect data for a long time

-f the data file name generated contains the time when the file was created.

The directory where the generated data files are stored is the current directory.
