The MDEX Engine Statistics page provides a detailed breakdown of what the Dgraph is doing, and is a useful source of information about your Guided Search implementation’s configuration and performance.
The statistics page is also called the Dgraph Stats page or Admin Stats page.
It provides information such as startup time, last data indexing time, and indexing data path. This allows you to focus your tuning and load-balancing efforts. By examining this page, you can see where the Dgraph is spending its time. Begin your tuning efforts by identifying the features in the Hot Spot Analysis section with the highest totals.
