Starting and stopping the Dgraph using Enterprise Manager
The Dgraph home page in Enterprise Manager has Start Up and Shut Down commands to manually start and stop the Dgraph and the Dgraph HDFS Agent as necessary.
Logging for Big Data Discovery targets in Enterprise Manager
Enterprise Manager provides standard logging controls to list, view, search, and download the log files for the Big Data Discovery targets. You can also group logging messages from each target by host, host IP address, or other parameters.
Configuring verbose logging for a Dgraph target
The Dgraph has logging enabled by default. 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.
