Monitoring Consumers
By monitoring Kafka consumer groups, you can track active and passive consumer groups,
or all consumer groups, which use the default internal __consumer_offsets topic
to store the consumed offset information. You can track additional details about consumer groups.
You can also track details including number of consumers and consumer instances included in a
group and consumer group lag in the consumer group profile.
Streams Messaging Manager (SMM) displays consumer groups that have offsets stored in Kafka's
internal topic __consumer_offsets, which is also the default store if the
auto.commit.enable property is set to true for consumers. SMM does not display
consumer groups that have offsets stored anywhere else other than this default store.
Viewing Summary Information about Consumer Groups
The Overview page gives you summary information about consumer groups
on the right side of the page. You can use the Active,
Passive, and All tabs to view consumer groups
only in the Active or Passives, or all of the consumer groups, which use the default internal
__consumer_offsets topic to store the consumed offset information. Use the
Lag tab to sort consumer groups based on ascending or descending amounts
of lag.
