Parameter Name | Description |
Group Name | Unique identifier of a consumer group. All consumers within the group jointly consume messages from the same topic, achieving load balancing. |
Status | Status of a consumer group, typically Online or Offline. The offline status indicates that there are no running consumer instances within this group. |
Consumption Mode | The options include clustering consumption and broadcasting consumption. Clustering consumption: Each message is consumed by only one consumer within the group. Broadcasting consumption: Each message is consumed once by every consumer within the group. |
Protocol Type | Communication protocols used by consumers, such as Transmission Control Protocol (TCP) and Hypertext Transfer Protocol (HTTP), determine the interaction method between the client and the broker. |
Filter Type | Method for filtering messages. The options include TAG and SQL92. TAG: Simple matching is performed based on the message tag. SQL92: Complex filtering is performed on message properties through custom structured query language (SQL) expressions. |
Filter Rule | Specific filter condition applied. For example, it may be TagA in TAG mode and a > 5 in SQL92 mode. |
Heaped Messages | Total number of unconsumed messages in a consumer group, which is a critical metric for measuring consumption health. Persistent backlog increase indicates that the consumption speed is lagging behind the production speed. |
Consumption Progress Update Time | Time when the consumption progress (offset) of this consumer group was last committed to the broker, reflecting the activity level of the consumer. If the consumption progress is not updated for a long time, the consumer may have entered a zombie status or stopped consumption. |
Operation | If certain groups under the topic are offline (that is, no online clients), you can click Unsubscribe in the operation column to clear historical subscription data, preventing businesses from being affected by historical dirty data. |
