System Administrators can access the Performance homepage by following these steps:
- Navigating to Self-Service > Homepage.
- Selecting ServiceNow Performance in the homepage selection box from the top left.
The top controls specify the time range and the size of the graph (I always select Extra Large!).
The other controls let you drill into a particular node, focusing on particular attributes. Choose the node that you want to view by selecting it in the CI selection list.
