MySQL Enterprise Monitor

Advanced Query Analyzer - Provides multiple options for quickly finding worst offenders. Collected queries can be sorted and filtered by server, database, query type, query content. Analysis can be done by current time intervals or by historical date/time range.

MySQL and OS Metric Graphs - Allows DBA to monitor and correlate these metrics: Database Activity (Selects, Inserts, Updates, Deletes)

I believe it has a free trial.
