Analyzing RAM Usage in Detail: A Guide to Checking VPS Memory Consumption

RAM is the hardware in a computing device that stores the operating system, applications, and current data for easy access by the processor. 

a) How to check the detailed RAM usage

1. First, log in to your VPS through SSH and then enter the free -m command in it.

2. Then, it will generate a table detailing RAM usage, similar to:

• Total: RAM limit set for your VPS plan
• Used: Memory currently in use
• Free: Unused memory
• Shared: Memory used by temporary files
• Buff/Cache: Memory used by kernel buffers and page cache
• Available: How much additional memory can your server use to perform further processes

Notes: The calculation method may result in a discrepancy between the total and the sum of used and available memory.
