Hi Marc,
i thought the process could be triggered by a cron, but if that is not
an option, historic data can not be collected, i guess. How about a
live monitoring tool? I could create a visualisation of the ratios of
the different query types. Constantly updating that with ajax would be
nice, and maybe even collecting the data in the browser and plotting
