PHP Manual

MongoDB\Driver\Monitoring\CommandStartedEvent::getOperationId

Returns the command's operation ID

Description

final public string MongoDB\Driver\Monitoring\CommandStartedEvent::getOperationId()

The operation ID is generated by the extension and may be used to link events together such as bulk write operations, which may have been split across several commands at the protocol level.

Note: Since multiple commands may share the same operation ID, it is not reliable to use this value to associate event objects with each other. The request ID returned by MongoDB\Driver\Monitoring\CommandStartedEvent::getRequestId should be used instead.

Parameters

This function has no parameters.

Return Values

Returns the command's operation ID.

Errors/Exceptions
