    597 We can access the Ping data from our scheduled test in a similar way. Going back to our Registered Services page, this time we access the PingER service on node PCC.

    601 While it's good to be able to query each service for its data, sometimes it's better to have access to all measurements in our slice on the same page. perfAdmin provides this option on the left menu for each of the regular testing measurement types currently supported (One-way Delay, Ping and Throughput). When we access one of these pages, perfAdmin will query each known service storing measurements of the given type for all the related metadata. It then builds a single page that we can use to query for a particular measurement's data. For example, if we go to the One-Way Delay page we should be able to see the measurements stored in both nodes PCA and PCC.
