You can see if the integration is active on the integration itself. This is indicated by the text 'Running' or for example 'Last sync 8 hours ago'. Additionally, there is a 'History' button on the integration. Clicking on it will show a line that can be clicked again. By doing this, a popup will appear with the history of the integration. Here you can see what the integration has processed and find error messages.
