Press K to kill a process while top is running, and then type the PID of the process that you want to kill.Īfter you press Enter, top asks for the signal type. You can also kill processes by using top. You might recall that we used the sudo kill -9 command earlier to kill a process. To kill or terminate a process, you have to send a kill signal to the process. Press I again to toggle the switch and show the idle processes, too. The following screenshot shows the output of top -i -u Only the process that has PID=19933 consumes CPU. Press I or run the top -i command to filter the top output to show only the processes that are consuming CPU. For example, if you run the top -u www-data command, it will yield the same output as you would get if you were to open the top tool and press U to filter by user. You can use filters when you run top command directly. These are the processes that run the two ASP.NET Core applications, while the other two processes belong to Nginx. When you inspecting the output of the filtered top view, you can see that two of the processes are. When you press Enter, you'll see the processes that are run by the given user (the www-data user in this example). The following screenshot shows the top tool filtering the available process snapshots for the www-data user. You can press U, and then type the username. One of the most common methods to do this is to filter processes by username.

To be able to target problematic resource consumption scenarios, it's important to know how to filter the top output. The next time that you run top, you'll see the columns that you selected. The changes will be saved for your user account. Use the arrow keys to move through the available columns, and use the Spacebar to select or deselect the columns. The columns that are marked by an asterisk (*) are the ones that are selected for display. To add or remove columns in the view that the top tool provides, press the F key while you run the tool. In this example, you can observe in the first listed process for PID 19933 that the process exhibits high CPU usage, and memory usage is also high. To open the Task Manager equivalent in Linux, run the top command.

This part will examine the top and htop command line tools to monitor processes. Linux has several tools that aim to achieve the same thing.

In Windows, you can use Task Manager to do this. When you troubleshoot a performance problem, you might have to monitor the CPU and memory usage of a process to understand how its resource consumption evolves over time. A Linux local firewall is enabled and configured to allow SSH and HTTP traffic.

Both ASP.NET Core applications are running as services that restart automatically when the server is rebooted, or the applications stops responding or fails.

The second website listens for requests by using the buggyamb ( host header, and routes the requests to the second ASP.NET Core sample buggy application that is listening on port 5001.

The first website listens for requests by using the myfirstwebsite host header ( and routes the requests to the demo ASP.NET Core application that is listening on port 5000.

However, you should have following items already set up if you followed all the steps of this training so far: PrerequisitesĪs in the previous parts, this part is structured to put more emphasis on the theory and principals to follow when you start to troubleshoot. This article introduces how to use top and htop command line tools to monitor processes.
