nagios monitoring tool

Collectl is a lightweight performance monitoring tool that monitors information such as CPU, disk, bandwidth, memory, network, NFS, and process. Monitoring System Resources is a necessary task for system administrators. We often need to monitor system resources to solve system problems. The Linux system also comes with many

We mentioned earlier that there are many Linux system monitoring tools that can be used to monitor system performance. However, we estimate that more users may prefer tools (top commands) that are included in most Linux distributions ). The top command is a real-time task manager in Linux. it is also used to find the system performance in the GNU/Linux release. We mentioned earlier that there are many Linux system

conky 6) The top Command provides a console-based constantly updated output that displays the processes currently running that consume the most cpu. The top command provides some interactive commands: h displays the help document, k prompts to enter the process to be killed, n prompts to enter the process to change the priority, r re-schedules the running process, q: Exit top. 7) The free command shows the number of used and idle memories. The Unit is kilobytes. You can use the-m option to spec
