Dimitri got dimstat 8.5 out. It now includes monitoring for InnoDB and a whole bunch of MySQL Add-Ons.
For the ones who haven't yet used it. It's an excellent, free and platform independent systems monitoring tool:
- Mixed monitoring for Linux and Solaris.
- Client Server technologies which allows to monitor multiple servers at a time
- full history: datapoints are being kept in a MySQL database
- Sample parameters and intervals fully configurable
- Browser based UI
