Many times you need to check the status of your server's CPU and RAM resources. For example, when there is a regiment. For this purpose, you can monitor these resources in several ways.

To know the status of your CPU and RAM usage, go to the dashboard section in the Hiddify panel. Here, various and useful information about the status of system resources as well as network card traffic information and online users can be seen in an integrated manner.

One of the tools that can be used to control resources in Linux servers is htop.

• First, connect via SSH to the server.

• and exit Hiddify menu by clicking Cancel or pressing ctrl+c keys at the same time. If the menu is still displayed after this, type the command clear and enter.

• Then if htop is not installed on your server, install it through the following command

apt install htop

Usually, this program is installed by default on Ubuntu 20.04 and 22.04.

• Then run this command to open htop.

htop

From this program, you can see the consumption of your server resources by each process.

• To see the amount of CPU consumption of each process, click on the CPU to sort accordingly and see which process has allocated a higher percentage of CPU to itself.

• Also, to see how much RAM is consumed by each process, click on MEM to sort accordingly.

• If the most resources are used by Hiddify services (such as hiddify-panel, hiddify-nginx, hiddify-xray, etc.), exit htop.

• To exit the htop environment, you must press ctrl+c or q.

• Then enter Hiddify menu once through the following command.

bash /opt/hiddify-config/menu.sh

• Select the restart option using the arrow keys (up and down) and wait until the services are restarted and exit the Hiddify menu again and check htop.

RAM memory is actually a temporary memory whose space is occupied by running services. Part of the memory is occupied by the operating system itself.

The amount of RAM is not directly related to the number of users on the panel. No matter how many users are defined in the panel, a series of services must be running in order for the operating system and peripheral services to work. Therefore, the number of users on the panel does not have a direct and linear relationship with the amount of RAM, but the running services have a direct relationship with the amount of RAM used.

The operating system is always in charge of managing the server's resources, and if the RAM in your server is filled up to 80%, it is a completely normal thing and you should not worry.

In Linux servers, do not reboot the system to solve the RAM filling problem.

• One of the ways to improve the server's RAM status is to empty the RAM cache. You can empty the cache with this command in the terminal server when you are logged in as the root user.

sync && systemctl -w vm.drop_caches=3

Be sure to log in as the root user and then execute this command.

• In addition to Hiddify panel dashboard that displays the status of the hard disk, the following command can also be used in the terminal.

df -h --total

whose output is as follows.

Here, the space related to sda1 should be checked according to the figure. If for any reason this space was full and you need to free up some space, you can delete the information related to the logs with the following command.

rm-rf /opt/hiddify-config/log/system/*

• The work is done
