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 each event notification. If the user does not specify an ID, OBS will automatically assign one.
- URN of the event notification topic. After detecting a specific event, OBS 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.
