MySQL flood attack?

Hi,

I have a dedicated server that hosts 4 websites, one has a vBulletin installed. All websites were running very slow this morning, the host narrowed it down to the MySQL service consuming much of the CPU's resources. Once that service was stopped performance on all the other websites was back to normal.

I have denied access to everyone aside from me and another IP address to the site with vBulletin and turned the MySQL service back on and everything is working fine.

Before I open the site back up to everyone can someone point me in the direction of a way to see if there was some kind of flood attack against the site? I'm looking through the server's logs but don't know what I should be looking for that would jump out at me.

Any suggestions would be much appreciated.

Thanks,
Scott
