Viewing Message Body

Overview

ROMA Connect provides a visualized message query function, which allows you to view the message data stored in topics on the console and view the message body more intuitively and conveniently.

Messages of only one topic can be queried at a time.

Procedure

Log in to the ROMA Connect console. On the Instances page, click View Console next to a specific instance.
In the navigation pane on the left, choose Message Queue Service > Message Query.

In the upper right corner of the page, select the topic whose messages are to be queried. The messages stored in the topic are automatically displayed.

You can also click Advanced Search, set search criteria, and click Search to search for messages.

Search By: method used for message query.

Creation time: Messages are queried by creation time.
Offset: Messages are queried by the location where the message is recorded in a partition.

If a broker is faulty and a topic with only one replica contains a large amount of data, an internal service error will be reported when you query messages in the topic. Shorten the time range for query based on the data volume.
