# Consumer Groups

Consumer group monitoring is a key part of operating Kafka. Lenses allows operators to view and manage consumer groups.

{% hint style="info" %}
The connector and SQL Processor pages allow you to navigate straight to the corresponding consumer groups.

The Explore screen also shows the active consumer groups on each topic.
{% endhint %}

## Viewing consumer groups <a href="#viewing-consumer-groups" id="viewing-consumer-groups"></a>

To view consumer groups and the max and min lag across the partitions go to **Environments->\[Your Environment]->Workspace->Monitor->Consumers**. You can also see this information for each topic in the **Environments->\[Your Environment]->Explore screen->Select topic->Partition tab**.

## View consumer group details <a href="#view-consumer-group-details" id="view-consumer-group-details"></a>

Select, or search for a consumer group, you can also search for consumer groups that are not active.

## Viewing alerts for a consumer group <a href="#viewing-alerts-for-a-consumer-group" id="viewing-alerts-for-a-consumer-group"></a>

To view alerts for a consumer group, click the view alerts button. Resetting consumer groups is only possible if the consumer group is not active. i.e. the application must be stopped, such as a Connector or SQL Processor. Enable the show inactive consumers to find them.​​

## Resetting consumer group for a specific partition to an offset <a href="#resetting-consumer-group-for-a-specific-partition-to-an-offset" id="resetting-consumer-group-for-a-specific-partition-to-an-offset"></a>

1. Select the consumer group
2. Select the partition to reset the offsets for
3. Specify the offset

## Resetting the whole consumer group <a href="#resetting-the-whole-consumer-group" id="resetting-the-whole-consumer-group"></a>

To reset a consumer group (all clients in the group), select the consumer groups, select **Actions,** and **Change Multiple offsets**. This will reset all clients in the consumer group to either:

1. To the start
2. To the last offset
3. To a specific timestamp
