Process Slice Manager

This repository contains a service for managing process slices and monitoring them via systemd. It allows for easy package changes, process management, and error monitoring.

Installation

To install the service and ensure it runs on startup, follow these steps:

1. Create the systemd service file:

   sudo nano /etc/systemd/system/process-slice-manager.service

2. Create the script that will be used by the service:

   sudo nano /usr/local/bin/process-slice-manager.sh

3. Make the script executable:

   sudo chmod +x /usr/local/bin/process-slice-manager.sh

4. Reload systemd to recognize the new service and enable it to start at boot:

   sudo systemctl daemon-reload
   sudo systemctl enable process-slice-manager.service
   sudo systemctl start process-slice-manager.service

Monitoring

To monitor the service logs, open another terminal and run the following command:

tail -f /var/log/process-slice-manager.log

Package change or update

When you change the hestia package, apply the changes by sending a HUP signal to the process manager:

sudo kill -HUP $(cat /var/run/process-slice-manager.pid)

Code Changes

If you have changed the code, reload the systemd daemon and restart the service:

sudo systemctl daemon-reload
sudo systemctl restart process-slice-manager.service

Test

1. Create a user in HestiaCP and create a web domain domain1.com with DNS settings. If you're on Windows, change the hosts file to point the domains to the Hestia server IP (192.168.209.58):

   192.168.209.58 domain1.com
   192.168.209.58 domain2.com

2. In HestiaCP, use the Folder Manager to navigate to the public_html folder of domain1.com. Delete index.html, replace it with index.php, and paste the contents of cpu_ram_stress.php from this repository.

3. You can now run the PHP test by setting the maximum amount of RAM and the percentage of CPU usage.

4. Check htop to see if the user is properly limited according to the package settings.
