My little experience with the ubuntu server today, I found out the server hdd space runs out quickly. I try to monitor with all the network tools I read in the google, but found nothing.
Then finally find out that the cause of it is syslog the log size. It reaches 3,5Gb. So big for the log lines isn’t it?
I don’t know how to empty it, the logrotate command does squeeze it to compressed archive but not change the syslog size. Until I found the command in here.
truncate -s 0 /var/log/syslog
That makes the syslog empty. But until an hour, it doesn’t filled again with line. I don’t what’s wrong, so I monitor it again.
