List Running Processes in Linux
In the web hosting industry it is very common to use Shared Hosting services. Shared Hosting is a type of web hosting where multiple users share their resources within a single server.
May be you are also using the same. Have you ever get an update regarding maximum consumption of resources or you have fully consumed your resources? If yes, then this article will really help you to know how can you manage it.
To make you understand the topic more I would like to explain it with an example. Suppose you open a chrome to open your website and in another tab you have log in your cPanel account and then managing files in another tab. So every time you open a new tab a process is being done.
Running Processes are basically the processes that are used to analyze the consumption of resources in a server. Even if you are not using shared hosting services then also you must track the consumption of your resources to check if unwanted process in running in the background or you want to modify the priority of any process.
So, today in this article, I will share the procedure with which listing of running processes will be easier.
