The dot between the pause button and the account button shows how busy the connections of the drive to the platforms are: - Hover over the dot for the load, such as "124% of the last 5 s in calls, 3 outstanding". With more than one database the tooltip also names the busiest one. - Choose the dot to open the window "Connection Monitor". Choosing it again brings the open window forward. The colour of the dot follows the load of the last seconds. The bands are "Idle", "Light", "Sustained", "Heavy" and "Saturated", from green through gold and orange to red and black. The dot is grey while the drive is paused, starting or stopping, and when the drive does not answer. The colour is never the only carrier: the percentage is also in the tooltip and in the name of the button for screen readers.  The window has the following parts: - The graph "Busy time of the connections per second" of the last 5 minutes. Drag across the graph to list only the calls that were running in that period. - The calls of the drive to the platforms, the newest first. Every line shows the start, the time, the connection, the action, the address, the cause and the result. The cause tells what in the drive made the call, such as "Explorer opened Invoices" or "Change poller". - Calls that the user did not ask for, such as those of the change poller and the catch-up after a start, in a separate colour in the graph. - The box "Search calls", and the options "Only failed" and "Exclude cached" to narrow the list. The line under the list shows how many calls are shown. - Select lines and press Ctrl+C to copy them. The results "Overload" and "Internal error" are shown in red. The results are the texts of the engine and are not translated. When the drive does not answer, the list shows the last known calls with a message.
