To monitor Linux server performance, you’ll need to install a node exporter utility that collects multiple hardware-related and kernel-related metrics (CPU, disk utilization, memory, network statistics, etc.), then makes them available to the Prometheus server to scrape.
2. Which method would you prefer while monitoring a Linux machine?
Another common method of monitoring remote Linux/Unix hosts is to use the NRPE addon. NRPE allows you to execute plugins on remote Linux/Unix hosts. This is useful if you need to monitor local resources/attributes like disk usage, CPU load, memory usage, etc. on a remote host.
3. How to check CPU health in Linux?
The sar tool is a utility for managing system resources. It’s not limited strictly to CPU usage, but you can use the -u option to track CPU performance. The –u option tells it to display CPU usage. The 5 indicates that it should display every 5 seconds.
4. How do I monitor and manage processes in Linux?
In Linux, Top command is utilized to monitor Linux Process which is used frequently used by many systems. It is available under many Linux, Unix-like operating systems. All the running and active real-time processes in the ordered list are displayed and updates it regularly by this Top command.
5. How do I monitor my CPU and RAM in Linux?
Open a terminal. Use the cat command to display the data held in /proc/cpuinfo. This command will produce a lot of text, typically it will repeat the same information for the number of cores present in your CPU. A more concise means to get most of this information is via lscpu, a command that lists the CPU details.
6. How to check hardware health in Linux?
vmstat is a Unix/Linux command that displays the status of the virtual memory kernel plus some other useful system statistics. It can be run by typing ‘vmstat 5’ which will display one line of data every 5 seconds until it is canceled.
7. Why should we monitor processes in Linux?
Processes need to be managed and monitored because they consume system resources like CPU time, memory, and disk space.
8. How do I monitor processes in real-time in Linux?
You can list running processes using the ps command (ps means process status). The ps command displays your currently running processes in real-time.
9. How to check RAM and CPU in Linux?

This command will produce a lot of text, typically it will repeat the same information for the number of cores present in your CPU. A more concise means to get most of this information is via lscpu, a command that lists the CPU details.
10. How to check CPU bottleneck in Linux?
Use the following tools to identify system bottlenecks on UNIX: top. View overall system performance. iostat. Monitor the loading operation for every disk attached to the database server. vmstat. Monitor disk swapping actions. sar. View detailed system activity reports of CPU, memory, and disk usage.
11. How to check GPU in Linux?
Checking GPU Information in Ubuntu. Once the terminal is open, type in the command “lspci” and press enter. This will display a list of all the PCI devices connected to your computer. Look for the
