Hi Bryan,
My first guess would be to use Nagios's check_mysql plugin. Just
because port 3306 (or whatever your MySQL server runs on) is open
doesn't mean the server is alive and well. check_mysql behaves as a
standard MySQL client, thus avoiding connection errors.
I use the latest plugins with Nagios 3.0.3, it works well and you get
the added bonus of some statistics (such as uptime, open tables,
long-running queries) in the Nagios front-end.
check_mysql is built as part of the standard plugins package providing
you have the MySQL client and developer libraries installed on your
Nagios server when you compile the plugins.
Regards,
Andy

I've got a nagios server that checks to see if the listening port is
open. I'm getting this error:
Host 'nagios-host' is blocked because of many connection errors;
unblock with 'mysqladmin flush-hosts'
I've googled and there's options to use max_connection_errors=1000000
My (very rough) estimate is that this will last a about 1 year before
the nagios server gets blocked again. What's the best way of dealing
with this?
