Patrol monitors system resources and records information to a log file in case of excessive RAM or CPU usage. When the log file reaches a certain size, it archives old log files up to a specified number. This is a useful tool for monitoring system performance and managing log files regularly.

• Monitors system resources (RAM and CPU usage).
• Records information to a log file.
• Archives old log files when the log file size exceeds a specified limit.
• Allows for customization of the log file size limit and the maximum number of archived log files.

1. Clone the repository:

   git clone https://github.com/mkdemir/patrol.git
   

2. Navigate to the project directory:

   cd patrol
   

3. Make the script executable:

   chmod +x patrol.sh
   

Run the script using the following command:

./patrol.sh

Alternatively, you can specify custom RAM and CPU thresholds using:

./patrol.sh -ram 20 -cpu 10 

The script will start monitoring system resources and logging information to a file named patrol-output.log. When the log file size exceeds a certain limit, old log files will be archived.

You can customize the following parameters in the script:

• RAM_THRESHOLD: The threshold for RAM usage (in percentage).
• CPU_THRESHOLD: The threshold for CPU usage (in percentage).
• RESET_THRESHOLD: The threshold for resetting the log file (in percentage). (Old)
• MAX_COMPRESSED_FILES: The maximum number of compressed log files to keep.
• LOG_FILE: The name of the log file.
• COMPRESSED_LOG_FILE: The name of the compressed log file.

To run the script as a service on Linux systems using systemd, follow these steps:

1. Navigate to the project directory:

   cd /path/to/patrol
   

2. Create a new service file using a text editor, for example:

   sudo nano patrol.service
   

3. Paste the following content into the service file:

   [Unit]
   Description=Patrol
   After=network.target
   
   [Service]
   ExecStart=/path/to/patrol/patrol.sh
   WorkingDirectory=/path/to/patrol
   Restart=always
   
   [Install]
   WantedBy=multi-user.target
   

   Note: Update the ExecStart and WorkingDirectory paths according to the location of your project.

4. Save and close the file (if you're using nano, press Ctrl + X, then Y, and finally Enter).

5. Copy the service file to the systemd directory:

   sudo cp patrol.service /etc/systemd/system/
   

6. Reload systemd to read the new service file and start the service:

   sudo systemctl daemon-reload
   sudo systemctl start patrol
   

7. Check the status of the service to verify that it started successfully:

   sudo systemctl status patrol
   

   The status output will indicate whether the service is running and if there are any errors.

8. Optionally, enable the service to start automatically at boot:

   sudo systemctl enable patrol
   

The system monitor and log rotator service is now successfully running! It will automatically monitor system resources and manage log files when the system starts up.
