  Script for monitoring disk space in Linux

  The script below is designed to monitor disk space usage on a specified server partition. Configurable parameters include the maximum allowable percentage of disk space usage (MAX), the e-mail address to receive alerts (EMAIL) and the target partition (PARTITION).

  The script uses the df command to collect disk usage information and sends email alerts if the current usage exceeds the specified threshold

  #!/bin/bash
  # Script: ./df_guard.sh [config_file]
  
  # Set the maximum allowed disk space usage percentage
  MAX=90
  
  # Set the email address to receive alerts
  EMAIL=user@example.com
  
  # Set the partition to monitor (change accordingly, e.g., /dev/sda1)
  PARTITION=/dev/sda1
  
  # Get the current disk usage percentage and related information
  USAGE_INFO=$(df -h "$PARTITION" | awk 'NR==2 {print $5, $1, $2, $3, $4}' | tr '\n' ' ')
  USAGE=$(echo "$USAGE_INFO" | awk '{print int($1)}') # Remove the percentage sign
  
  if [ "$USAGE" -gt "$MAX" ]; then
  # Send an email alert with detailed disk usage information
  echo -e "Warning: Disk space usage on $PARTITION is $USAGE%.\n\nDisk Usage Information:\n$USAGE_INFO" | \
  mail -s "Disk Space Alert on $HOSTNAME" "$EMAIL"
  fi

  Anubis is usually installed in such a case.
