Instructions
To receive notifications when your disk space on your Ubuntu server is running low, you can use the df command to monitor disk usage and set up alerts using the mail command. Here’s how you can do it:
Install the mailutils package if it’s not already installed on your server:
´sudo apt-get install mailutils´
Create a script to send an email notification when disk space is low:
Copy code #!/bin/bash
Set your email address here
email="you@example.com"
Set the threshold for low disk space (in percentage)
threshold=90
Get the current disk usage
df -h / | awk '$NF > "{{threshold}}%" {print $1}' | while read disk; do # Check if the disk usage is above the threshold if [ "$disk" -gt "$threshold" ]; then # Send an email notification echo "Disk $disk is full!" | mail -s "Disk Full Alert" "$email" fi done
Save the script as disk_full_alert.sh and make it executable:
Copy code chmod +x disk_full_alert.sh
Set up a cron job to run the script daily:
Copy code sudo crontab -e Add the following line to the crontab file:
Copy code 0 0 * * * /path/to/disk_full_alert.sh This will run the script at midnight every day.
Now, you should receive an email notification when the disk space on your server is running low. You can adjust the threshold variable in the script to set the disk usage percentage at which you want to receive notifications.
