@dnitzel as you have 2 WANs the graph only shows total traffic, so your peak of 250Mbps could be 125Mb upload and 125Mb download at the same time. It is likely to be less evenly split but unfortunately you cannot tell when you have 2 WAN links. The WAN1 link seems to be doing very little, is it in use? What firmware/license are you on, I am running 15.32 on the unit I showed and the Enterprise license, sorry I don't see that graph and don't know what it is supposed to show, if you hover over the (i) does it include https, QUIC etc.? I'd guess it is fairly useless for overall traffic metrics. For the clients if you have more than an MX, select only security appliance clients and you should see a better representation of the WAN load, though again it is total traffic, i.e. upload and download. Unless you have a lot of backups from local sources to cloud or streaming to cloud, then I would assume that if you take either the uplink total or the security appliance client total, this should show roughly what line speed you are using now, I'd take 3/5 of that as a best guess for download going by the client total vs upload vs download, though I think 4/5 is more usual looking at other sites of ours. Therefore in your case I'd say you have 200Mb peaks which actually matches your line speed.
