How do I monitor a process in Linux?

Summary of the article:

If we want to have an idea of a single process, we can use the -p parameter. The shell will refresh this screen once every a couple of seconds to give us an updated view of a process’ status.

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 system. All the running and active real-time processes in ordered list is displayed and updates it regularly by this Top command.

All operating systems include a utility that shows current processes. In Windows, this utility is the Task Manager. To get it, right-click on the Taskbar and select Task Manager from the pop-up menu that appears. This utility list all processes in categories.

To list processes in Linux, use one of the three commands: ps, top or htop. Ps command provides static snapshot of all processes, while top and htop sorts by CPU usage.

Process Monitor (Procmon) is a Linux reimagining of the classic Procmon tool from the Sysinternals suite of tools for Windows.

A process is nothing but running instance of a program and each process has a unique PID on a Unix-like system. The easiest way to find out if process is running is run ps aux command and grep process name. If you got output along with process name/pid, your process is running.

The iotop command is used to monitor, I/O usage information, using the Linux kernel. It shows a table of current I/O usage sorted by processes or threads on the server.

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.

/var/log. This is such a crucial folder on your Linux systems. Open up a terminal window and issue the command cd /var/log. Now issue the command ls and you will see the logs housed within this directory.

top – Process activity monitoring command.vmstat – Virtual memory statistics.w – Find out who is logged on and what they are doing.ps – Displays the Linux processes.free – Show Linux server memory usage.iostat – Montor Linux average CPU load and disk activity.sar – Monitor, collect and report Linux system activity.

First, let’s switch to the directory where you can find Linux system logs with the command cd /var/log. Then, you can type ls to see the logs stored under this directory. One of the most important logs to view is the syslog, which logs everything but auth-related messages.
