Peering is a massively powerful and flexible feature that is often missed by many customers. Its been around for a number of major versions, but it has been improved recently with the release of Logger 5.5. Specifically it is faster, easier to setup and works across searches, dashboards and reports. I created a simple video to cover the process of the setup and how it operates in action - all on a video.
I hope that you all find it useful and lets get using Peering more and more!!!
