We don't need to visualize data about more than one server.
Just getting a list of servers and visualizing data about one server is too
slow.
Getting list of per proc metrics is too slow and not user friendly.
Getting a list of servers means reading these thousands of archives. And
slowest part is a reading of a last archive for each server (that pmlogger
is writing to).
