How to understand the "Gateway activity" in the LoRaAppServer web page?

As shown in the following figure.

What dose the blue histogram mean, especially their height ?

I want to show this “gateway activity” in my own application, but I can’t find any related API in REST API page.
Is there any other method to achieve my goal ?

Thanks a lot !

It is not intended as a full graph. E.g. it gives you a quick overview of the “activity” (sent / received). For the full graph, click on the gateway :slight_smile:

Thanks for your answer.
I have another problem, how to get the historical record of gateway activity ?
The REST API you provide(/api/gateways/{mac}/stats) only shows the current state.

Sorry, I was wrong. :upside_down_face:
I can get the historical record of gateway activity by REST API(/api/gateways/{mac}/stats).
I forgot to provide a start and stop timestamp as the following figure show:
