Greetings,

I've been keeping track of Bytes_sent and Bytes_received for a while in
the fashion of 'mysqlreport': divide those values over Uptime in order
to obtain a data rate (bytes/sec).

The resulting graphs look like this:

|   /  |   /
|  /   |  /

Bewildered I started troubleshooting, and I think I have found the
cause: the value of Bytes_* has a maximum value of around 4GB, or the
size of an INT UNSIGNED.

Can anyone confirm that this is the max value for status variables?

Yes, bytes_sent and bytes_received are type unsigned long (4 bytes), so
max value is 4.2G.
