Event Notification Overview

If you have any questions during development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see API Reference.

OBS provides the event notification function. When this function is enabled, you will be notified of all specified operations on the bucket through simple message notification (SMN). Event notification contains the following configurations:

  • Unique ID of an event notification. If the user does not specify an ID, OBS will automatically assign one.
  • Uniform resource name (URN) of the event notification topic. When OBS detects a specific event in the bucket, it sends a message to the topic.
  • Type of events that need to be notified.
  • Filtering rules. Objects can be filtered based on the prefixes or suffixes.

    For more information, see Event Notifications.

For details about the operations on FunctionGraph, see Using an OBS Trigger.
