Trace Message Delivery by ID via OnsMessageGetByMsgId - ApsaraMQ for RocketMQ - Alibaba Cloud - ApsaraMQ for RocketMQ

Queries the information about a message by specifying the message ID and determines whether the message has been consumed.

Operation description

Note

API operations provided by Alibaba Cloud are used to manage and query resources of Alibaba Cloud services. We recommend that you integrate these API operations only in management systems. Do not use these API operations in the core system of messaging services. Otherwise, system risks may occur.

If a message is not consumed as expected, you can call this operation to query the information about the message for troubleshooting.
This operation uses the exact match method to query a message based on the message ID. You can obtain the message ID from the SendResult parameter that is returned after the message is sent. You must store the returned information after each message is sent. The queried information about a message includes the point in time when the message was sent, the broker on which the message is stored, and the attributes of the message such as the message key and tag.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
