Consuming Messages from a Channel

• Console
• CLI
• API

• You can't use the Console to consume messages, but you can use the Console to poll for messages. Polling messages serves as a peek at the queue or channel. Messages polled by the Console are unavailable to other consumers until the visibility timeout passes.

  1. On the Queues list page, select the queue that you want to work with. If you need help finding the list page or the queue, see Listing Queues.
  2. On the details page for the queue, select Channels.
  3. (Optional) Select Manage polling settings. Provide the following information and then click Save changes:
     • Polling timeout (seconds): The length of time to wait for messages to consume.
     • Number of messages in a request: The maximum number of messages to consume when polling.
  4. Select Poll random channel or select the the Actions menu () for a specific channel and select Poll message.
  5. Select Continue.

     If messages are available for consumption, they displayed in the Poll channel messages panel along with the queue's name and the channel ID.

  6. Select a message to get more details about a message.

• Use the oci queue messages get-messages command and required parameters to consume messages from a channel. To consume messages from a specific channel, include channel-filter. For example:

  oci queue messages get-messages --queue-id <queue_OCID> --channel-filter <channel_ID>

  For a complete list of parameters and values for CLI commands, see the CLI Command Reference.

• Use the GetMessages operation to consume messages from a channel. A GetMessages request contains an optional limit, an optional visibilityInSeconds, and an optional timeoutInSeconds parameter.

  To consume messages from particular channels, include the channelFilter parameter.
