Every once in while I need to log slow queries using the JDBC logging parameters and it always takes me a while to find this information. So here it is (line breaks for readability):
?profileSQL=true&
slowQueryThresholdMillis=100&
autoSlowLog=true&
explainSlowQueries=true&
gatherPrefMetrics=true&
logSlowQueries=true
Simply add the above parameters to your JDBC connection string.
