Monitoring bandwidth usage per user is useful for identifying high-traffic accounts, troubleshooting resource usage, and managing hosting limits. If you have SSH access to a cPanel server, you can quickly check individual user bandwidth consumption using a simple shell script.<\/p>\n
Log in to your server via SSH and create a new file:<\/p>\n
vi<\/span> bandwidth<\/code><\/pre>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\nAdd the following script:<\/p>\n
\n\n\n\n\n\n\n\n\n<\/div>\n<\/div>\n<\/div>\n\n\n\n\n\n#!\/bin\/bash<\/span>\n\ncd<\/span> \/var\/cpanel\/bandwidth\/\n\nls<\/span> | grep<\/span> -v<\/span> \"\\.\"<\/span> | xargs -n<\/span> 1<\/span> -izzz<\/span> sh<\/span> -c<\/span> '<\/span>\necho -n zzz \" = \";<\/span>\negrep \"^$1\\..*\\.$2-all\" zzz | awk -F\"=\" \"<\/span>\nBEGIN {bytes=0}<\/span>\n{ bytes+=\\$2 }<\/span>\nEND {print bytes\/1024\/1024 \\\" MB\\\"}\"<\/span>\n'<\/span>\n\ncd<\/span> -<\/span><\/code><\/pre>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\nStep 2: Make the Script Executable<\/h2>\n
Save the file and provide execute permissions:<\/p>\n
\n\n\n\n\n\n\n\n\n<\/div>\n<\/div>\n<\/div>\n\n\n\n\n\nchmod<\/span> +<\/span>x bandwidth<\/code><\/pre>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\nStep 3: Run the Script<\/h2>\n
Execute the script by passing two parameters:<\/p>\n
\n- Month<\/strong><\/li>\n
- Year<\/strong><\/li>\n<\/ul>\n
Syntax:<\/p>\n
\n\n\n\n\n\n\n\n\n<\/div>\n<\/div>\n<\/div>\n\n\n\n\n\n.\/bandwidth month year<\/code><\/pre>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\nExample:<\/p>\n
To check bandwidth usage for January 2012<\/strong>:<\/p>\n\n\n\n\n\n\n\n\n\n<\/div>\n<\/div>\n<\/div>\n\n\n\n\n\n.\/bandwidth 1<\/span> 2012<\/span><\/code><\/pre>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\nStep 4: Display Top Bandwidth Consumers<\/h2>\n
To list the top 10 users consuming the highest bandwidth:<\/p>\n
\n\n\n\n\n\n\n\n\n<\/div>\n<\/div>\n<\/div>\n\n\n\n\n\n.\/bandwidth 1<\/span> 2012<\/span> | sort<\/span> -nrk<\/span> 3<\/span> | head -10<\/span><\/code><\/pre>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\nThis command will:<\/p>\n
\n- Sort the output in descending order<\/li>\n
- Display the accounts with the highest bandwidth usage first<\/li>\n
- Show bandwidth usage in MB<\/strong><\/li>\n<\/ul>\n
Example output:<\/p>\n
