System Monitoring
System monitoring is a helpful approach to provide the user with data regarding the actual timing behavior of the system. Users can perform further analysis using the data that these monitors provide. One of the goals of system monitoring is to determine whether the current execution meets the specified technical requirements.
These monitoring tools retrieve commonly viewed information, and can be used by way of the command line or a graphical user interface, as determined by the system administrator. These tools display information about the Linux system, such as free disk space, the temperature of the CPU, and other essential components, as well as networking information, such as the system IP address and current rates of upload and download.
