use charts with 2 y scales (left - right)
When I try to visualize 2 quantities i.e. the number of connected clients and the memory usage the scale makes it impossible (memory in the millions, connected clients under 100). Not sure what is the best solution, plus if you add more quantities there may be no solution at all, but 2 different y scales (e.g. memory on the left, connection on the right) may improve things
This weird behavior will be fixed with the rewritten monitoring module, stay tuned!
