# Consumer groups

Available in VPC

This article will explain how to check the status of consumer groups in the **Topic** menu. You can monitor the rack size of consumer groups and the offsets currently being processed by time zone to infer various abnormal situations such as real-time data processing delays, bottlenecks by consumer group, and lack of system resources, and effectively utilize them for cause analysis and tracking.

## Check consumer group status

To check consumer group status:

1. In the VPC environment of the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Big Data & Analytics** > **Data Stream**.
2. Click the **Topic** menu.
3. In the topic list, click **View service details**.
4. On the topic detailed interface, click the **[Consumer group]** tab menu.
5. When the interface appears, set the target consumer group and search period in the search filter.
  - Set search target Select the **Consumer Group** to view by clicking it in the consumer group drop-down list
  - Set search period
    - Last hour, last day, last 7 days, last 1 month
    - Custom: Click ![i-arc-brain_calendar](https://cdn.document360.io/6998976f-9d95-4df8-b847-d375892b92c2/Images/Documentation/i-datastream_calendar.png?sv=2026-02-06&spr=https&st=2026-11-14T05%3A16%3A21Z&se=2026-11-14T06%3A16%3A21Z&sr=c&sp=r&sig=%2B6doY9mPY1Zs9%2B1YCZdnBgmuJXiQ%2Bbr4m93j8CqMpVw%3D) to configure

  - **Consumer group lag**: Lag information by partition for the consumer group (unit: Num)
    - The closer it is to 0, the more real-time processing there is without delay
  - **Consumer group current offset**: Offset information by partition last processed by the consumer group (unit: Num)

              Note
