The All Targets page provides a table that lists the Big Data Discovery clusters and corresponding status (up or down).

You can view resource utilization, and search Dgraph queries and export your search results to a file in Excel. You can also search and export the HDFS Agent information.

The plug-in also relies on preferred credentials for two of the Big Data Discovery targets — Dgraph and Studio, and sets them automatically at discovery time to the host credential. Many features of the plug-in depend on these credentials being set.

The Dgraph target uses additional logging variables to enable or disable verbose logging. You can enable verbose logging for a Dgraph node, as a whole, or for a limited set of search features that are run by the Dgraph process on a node.
