The other day I got a warning message that my server’s file system was full. I was like ‘WTF? this is a new server image’. So I used a quick command in terminal (below) and found that the error log was 19GB in 404 errors (WHOOPS!).
# du -a /var | sort -n -r | head -n 10
Also check out the new toolnames.com I rebuilt it from the ground up making it much simpler and 10 times faster.
