Monitoring and backing up data domains

Obtaining information about data domains
You can list one or more data domains using endeca-cmd list-dd, or the operations from the Manage Web Service.

Monitoring the data domain health
Use the endeca-cmd get-dd-health to check the health of the data domain and list the status of the Dgraph nodes, including details about each Dgraph process that is not running. Alternatively, you can use the getDataDomainHealth request of the Cluster Web Service.

Checking the status of the data domain nodes
A quick way of checking the health of a Dgraph node in the data domain is to get its status from the Endeca Server. Use the endeca-cmd get-dd-status command, or the getDataDomainStats from the Manage Web Service, to obtain information about the size of the data domain's index, the number of indexed records, and the Dgraph statistics page.

Backing up the index
To back up a data domain's index, take a snapshot of the index files by exporting them. You can later restore the index to this particular state.

Collecting debugging information
Before attempting to debug an issue with the data domain, collect the following information.
