Administrative operations for the Dgraph

Use administrative operations to check Dgraph statistics, enable or disable diagnostic flags, without having to stop a running Dgraph. This section lists the supported administrative URLs, describes the functions of each URL, and defines the syntax of those URLs.

Syntax of administrative operations
Administrative operations use the following syntax.
List of administrative operations
Administrative (or admin) operations listed in this topic allow you to control the behavior of the Dgraph processes in a data domain.
help
/admin/datadomain?op=help returns the usage page for all of the administrative operations.
flush
/admin/datadomain?op=flush flushes the Dgraph cache. This operation must be run locally from the machine running the Oracle Endeca Server.
logroll
/admin/datadomain?op=logroll forces a query log roll. This operation must be run locally from the machine running the Oracle Endeca Server.
merge
/admin/datadomain?op=merge forces a merge, and (optionally) changes the merge policy of a running Dgraph. In a data domain cluster of Dgraph nodes, this command is routed to the leader node of the data domain cluster where it is processed. This operation must be run locally from the machine running the Oracle Endeca Server.
ping
/admin/datadomain?op=ping checks the aliveness of a Dgraph and returns a lightweight message.
stats
/admin/datadomain?op=stats returns the Dgraph Server Statistics page. Note that this page is intended for use by Oracle Support only. This operation must be run locally from the machine running the Oracle Endeca Server.
statsreset
/admin/datadomain?op=statsreset resets the Dgraph Server Statistics page. This operation must be run locally from the machine running the Oracle Endeca Server.
