Today I get an alert mail from linode.com "Your Linode, Randy, has exceeded the notification threshold (1000) for disk io rate by averaging 1571.81 for the last 2 hours.".
Last time I get alert like that is several month ago, I keeping get alerts, but at the same time my website network traffic never grow. I try everything, but can not location the problem. Finally, I guess the growing log file size is the problem. I use cronolog cut log file, and problem resolved.
Now,I/O rate chart shows I/O rate is keeping growing too, how to I location problem? Is there anything can help me?
My server is Ubuntu 8.04.4 LTS/apache/php/mysql at linode.com.
