Here we present a thumbnail sketch of all the assertions for the entities that match the search expression. This helps surface the hot spots in the system so a user can jump right in. By default, the health of the top services and top nodes are shown. By 'top' we mean the entities that have the most assertions and are the ones that would require attention. The user can customize this to use a different search expression that matches their needs. On hovering over the thumbnail sketch, a tooltip summarizing the assertions that happened during that period is presented.
