MongoDB\Driver\ServerDescription::getHelloResponse
(mongodb >=1.13.0)
MongoDB\Driver\ServerDescription::getHelloResponse — Returns the server's most recent "hello" response
Description
Returns an array of information describing the server. This array is derived from the most recent (at the time the MongoDB\Driver\ServerDescription was constructed) » hello command response obtained through » server monitoring.
Note:
When the driver is connected to a load balancer, this method will return an empty array since load balancers are not monitored. This is in contrast to MongoDB\Driver\Server::getInfo(), which would return the backing server's » hello command response from the initial connection handshake.
Parameters
This function has no parameters.
Return Values
Returns an array of information describing this server.
Errors/Exceptions
- Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.
