I like what I see from HP RUM, my issue is that the pricing and model for it don't work in a shared environment. I can't nail down each application, webserver, application server, or environment. I prefer to deploy it at the edge of the datacenter and just use it as needed. This is how we deploy and use our current real user monitoring from Coradiant. HP has been trying to be flexible, and create a pricing model that works for us over the last 6 months, but we haven't made the kind of progress that I need to see.
We can't test or deploy a solution which isn't cost effective compared to what I am getting from my current vendor. I don't want to POC the product if it doesn't make financial sense. Hopefully at HP Software Universe we'll make more progress, and enable us to test the product. Ultimately the solution is very compelling and fits nicely with our usage of Business Availability Center (BAC) and related products.
