Unfortunately we don’t support relative time frames right now so when you go to the graphs it uses the current time so you need to click the time graphs to refresh them again

But why did the first time I have installed the Librenms can automantically select the current time to show in graph view after 5 minitues page refresh ?

What version was that? I don’t recall that being a thing but then I’ve not really used LibreNMS for 12+ months.
