If you are a reseller, is there some way you can see if the server is being DoSSed by just having the IP?

Thank you,

Why do you believe that the server is being DoSSed?

Yes, I am also currious to know why you think the server is being DDoSed. At the least, you could inquiry to their datacenter if you know who they use, and just alert them of the DDoS attack, other than that, there is nothing much you can do on your end unfortunately.
