The ram size can be viewed under Red Hat Enterprise Linux on a desktop or server-based system with the following command lines: /proc/meminfo file – free – top – command How To Check High Memory Utilization In Linux?Ĭhecking high memory utilization in Linux is an important part of keeping your system running smoothly. In terms of the total number of RAM slots on a VPS, 842752 kB or 823 MB of that RAM is not used and thus is not free. I’m looking at a VPS with 1024 MB of total system memory, which is one GB of RAM.

The /proc pseudo-file system on Linux allows you to gain a better understanding of how the Linux kernel and various configuration files interact. It is simple to return another application’s memory to its original state if it requires more memory. Because the Linux operating system uses a page cache, it will try to move them there as quickly as possible. You should be aware that this applies to your applications and scripts that are hosted on your server. When reading the access_log file on disk, the time took 30.056 seconds, but when reading the file on RAM, the time took only 0.168. You can easily interact with the Linux page cache by using vmtouch, a fantastic tool. When you look up a list of free RAM resources on the internet, the most common way to find out what is free in Linux is by using the free command. When you use the free -m command to check your Linux memory usage, you can see the values as MB rather than KB.

Additionally, it will explain how to free up memory when running low and how to prevent memory problems in the future.

This article will discuss the various methods and commands you can use to check your system’s available memory and make sure you don’t run out of it. Fortunately, there are a number of ways to check if you are running low on memory in Linux. Memory is a vital resource for any computer system and running out of memory can lead to poor performance or even system crashes. If you are using Linux as your operating system, it is important to know how to check if you are running out of memory.
