Is it possible to easily know in Cube interface on which agent a user is connected. For now, it seems the information is not available for example on this page.
Is the information only available via information events?
Users logging in and out generates information events, which you could perhaps track to keep an overview, since it contains the DMA.
On system center, there also an Activity tab for each individual user where you can find this information. The IP will only be added in case the DMS is a cluster, but if not then the IP is always known anyway. In this case, I'm however not sure how to request this in an automated way.
