ping

/admin?op=ping checks the aliveness of an MDEX Engine and returns a lightweight message.

You can view the MDEX Engine Statistics page to check whether the MDEX Engine is running and accepting queries, but that comes with some overhead. A quicker way to check the aliveness of a Dgraph or an Agraph is by running the ping command.

The ping command returns a lightweight page that lists the MDEX Engine, the current date and time, such as the following:

dgraph example.endeca.com:8000 responding at Wed Oct 25 15:35:27 2009

You can use this operation to monitor the health or heartbeat of the MDEX Engine, and as a health check for load balancers.

Agraph support

The ping operation is supported in the Agraph.
