+The get_connected_users script is built so as to allow to multiply the charts, 
+for example checking for connected users in the last 5, 30 and 120 minutes.
+To do this, just make a copy of the script with "5" in the name to other
+scripts with the same name except for the 5 (both "munin" and "munin_proxy"
+scripts). The scripts will change depending on their name.
