SDWAN Application monitoring

Anyone have notice issue with custom app monitoring on SDWAN, we are seeing monitoring probs are being generated by IONs and going through Prisma, while our application is in datacenter, we couldn't find a way to force probs go through SDWAN tunnel to DC. Also how does APP score gets calculated, we notice on Prisma same APP is 80 and on SDWAN its 35, I expect SDWAN to be high or atleast near to Prisma
