Why do I need Nmon?

Nmon is needed by those who want to have a convenient and intuitive way to track various performance parameters of their system, such as CPU usage, memory, disks, network, processes, virtual machines, file systems, resources, and others. Nmon allows you to:

• Display performance statistics on the screen in a compressed format, updating the data every two seconds. You can turn on and off different types of data by pressing single keys on the keyboard. You can see CPU, memory, network, disks (mini-graphs or numbers), file systems, NFS, top processes, resources (Linux version and processors) and information about micro-partitions on Power1.
• Save data to a CSV file for later analysis and charting. You can use nmonchart (from this site) to generate charts in a web page using Google-chart. You can also use nmon Analyser, a Microsoft Excel spreadsheet that downloads a file with nmon data and automatically creates dozens of graphs to study or write performance reports.

How can Nmon be useful in business?

Nmon can be useful in business for several reasons:

• You can improve the efficiency and quality of your work by using Nmon to monitor the performance of your system and identify possible problems or bottlenecks. You can easily compare different parameters and determine their impact on the operation of the system.
• You can save time and money by using Nmon instead of other performance monitoring tools that can be difficult or expensive to use or maintain. You can install Nmon on your server and work with it through a terminal or web browser, without depending on other programs or services.
• You can maintain freedom and openness by using Nmon as an open source project licensed under the GPL. You can also contribute to the development of Nmon or receive support from the community.

What are the advantages and disadvantages of Nmon?

Advantages of Nmon:

1. Simplicity: You don't waste time learning complex tools or interfaces. You get all the necessary functions for performance monitoring in a convenient way.
2. Visibility: you not only collect data, but also see it. You see the structure and dynamics of your system during operation.
3. Flexibility: You can work with data in different formats and ways. You can display the data on the screen or save it to a file. You can analyze the data using different programs or services.

Disadvantages of Nmon:

1. Complexity: You must have certain knowledge and skills to install, configure and use Nmon on your server, as well as to solve possible network, performance or compatibility problems.
2. Responsibility: You are responsible for maintaining and updating your server and Nmon, as well as for data backup.
3. Limitations: You may encounter some limitations in Nmon functionality or performance when working with very large or complex systems.

Where and by whom is Nmon used?

Nmon is used in various fields and industries, such as:

• Software Development: Nmon is used to monitor the performance of applications and services being developed or launched.
• Education: Nmon is used to teach and demonstrate various aspects of the performance of the system and its components.
• Healthcare: Nmon is used to monitor the performance of medical software and systems.
• Law enforcement: Nmon is used to monitor the performance of software and systems to protect information and communications.

Why should I use Nmon specifically?

Nmon should be used exactly when you need it.:

• Have a convenient and visual way to monitor the performance of your system
• Use a free and simple performance monitoring tool
• Work with data in different formats and methods
