MongoDB\Driver\ServerDescription
PHP Manual

MongoDB\Driver\ServerDescription::getHelloResponse

Returns the server's most recent "hello" response

Description

final public array MongoDB\Driver\ServerDescription::getHelloResponse()

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.
