Can the MoonBot terminal quickly see basic exchange limits, latency values, API errors, current computer load?

Yes, you can do this by clicking on the green circle at the bottom left of the MoonBot terminal. This will open a small “Info” window with brief specifications: VDS mode on (ON) or off (OFF), if you are working on a local computer, this mode should be turned off, if on a remote server (VDS), then enable via Menu-System Settings – “VDS optimized mode” with a reboot of the MoonBot terminal.
Below are the API limits for the current connection to the exchange (for spot trading there will be one limit, for futures trading there will be another). Connections to the Web Socket – OK
Trades and Latency, which shows the delay of trades from the exchange as well as the value of the PriceBug parameter, CPU load, system load and memory usage.
At the very bottom is information on whether the separate Moon Streamer service is enabled (ON) or disabled (OFF), which can be configured by clicking on Settings. Moon Streamer is a separate server located in the Tokyo location, which sends current trades from itself over a UDP connection. If your direct connection to the exchange is not stable, a Moon Streamer connection can help you see the chart in real time. This is effectively an additional redundant channel for sending charts to your MoonBot terminal. If you’re trading on a VDS (remote server) there’s not much to gain by using Moon Streamer, it’s mainly useful if you’re trading on your local computer. Moon Streamer is an optional paid module which can be activated for Moon Credits in a separate window.
