Palworld Server Monitor

English | 简体中文

This Ruby script is specifically crafted to address memory shortages frequently encountered in Palworld dedicated servers. As the Palworld server environment often faces memory constraints, this script is engineered to monitor memory usage diligently. When the memory usage surpasses the designated threshold, the script initiates an automatic cleanup of Linux memory. However, if memory usage persists above the threshold even after executing the cache cleaning script, this script will restart the Palworld server service.

Configuration

Copy the example configuration file

$ cp ./configs/settings.example.yml ./configs/settings.yml

# configs/settings.yml

services:
  palworld_service: "pal_server" # systemctl service name_relative
  restart_threshold: 95 # Once above this threshold, palworld_service will clean caches and restart
rcon_connection: # modify Pal/Saved/Config/LinuxServer/PalWorldSettings.ini to enable rcon
  enable: false # when this option is enabled, palworld server will broadcast a message before the server be restarted.
  host: localhost
  port: 25575 # RCONPort in PalWorldSettings.ini
  password: # AdminPassword in PalWorldSettings.ini

Usage

Monitor RAM usage
