This tool helps to list all consumer groups, describe a consumer group, delete consumer group info, or reset consumer group offsets.
Option Description
------ -----------
--all-groups Apply to all consumer groups.
--all-topics Consider all topics assigned to a
group in the `reset-offsets` process.
--bootstrap-server <String: server to The server(s) to connect to. REQUIRED
connect to> for all options except for --
validate-regex.
--by-duration <String: duration> Reset offsets to offset by duration
from current timestamp. Format:
'PnDTnHnMnS'
--command-config <String: command Property file containing configs to be
config property file> passed to Admin Client and Consumer.
--delete Pass in groups to delete topic
partition offsets and ownership
information over the entire consumer
group. For instance --group g1 --
group g2
--delete-offsets Delete offsets of consumer group.
Supports one consumer group at the
time, and multiple topics.
--describe Describe consumer group and list
offset lag (number of messages not
yet processed) related to given
group.
--dry-run Only show results without executing
changes on Consumer Groups.
Supported operations: reset-offsets.
--execute Execute operation. Supported
operations: reset-offsets.
--export Export operation execution to a CSV
file. Supported operations: reset-
offsets.
--from-file <String: path to CSV file> Reset offsets to values defined in CSV
file.
--group <String: consumer group> The consumer group we wish to act on.
--help Print usage information.
--list List all consumer groups.
--members Describe members of the group. This
option may be used with '--describe'
and '--bootstrap-server' options
only.
Example: --bootstrap-server localhost:
9092 --describe --group group1 --
members
--offsets Describe the group and list all topic
partitions in the group along with
their offset lag. This is the
default sub-action of and may be
used with '--describe' and '--
bootstrap-server' options only.
Example: --bootstrap-server localhost:
9092 --describe --group group1 --
offsets
--reset-offsets Reset offsets of consumer group.
Supports one consumer group at the
time, and instances should be
inactive
Has 2 execution options: --dry-run
(the default) to plan which offsets
to reset, and --execute to update
the offsets. Additionally, the --
export option is used to export the
results to a CSV format.
You must choose one of the following
reset specifications: --to-datetime,
--by-duration, --to-earliest, --to-
latest, --shift-by, --from-file, --
to-current, --to-offset.
To define the scope use --all-topics
or --topic. One scope must be
specified unless you use '--from-
file'.
--shift-by <Long: number-of-offsets> Reset offsets shifting current offset
by 'n', where 'n' can be positive or
negative.
--state [String] When specified with '--describe',
includes the state of the group.
Example: --bootstrap-server localhost:
9092 --describe --group group1 --
state
When specified with '--list', it
displays the state of all groups. It
can also be used to list groups with
specific states.
Example: --bootstrap-server localhost:
9092 --list --state stable,empty
This option may be used with '--
describe', '--list' and '--bootstrap-
server' options only.
--timeout <Long: timeout (ms)> The timeout that can be set for some
use cases. For example, it can be
used when describing the group to
specify the maximum amount of time
in milliseconds to wait before the
group stabilizes (when the group is
just created, or is going through
some changes). (default: 30000)
--to-current Reset offsets to current offset.
--to-datetime <String: datetime> Reset offsets to offset from datetime.
Format: 'YYYY-MM-DDThh:mm:ss.sss'
--to-earliest Reset offsets to earliest offset.
--to-latest Reset offsets to latest offset.
--to-offset <Long: offset> Reset offsets to a specific offset.
--topic <String: topic> The topic whose consumer group
information should be deleted or
topic whose should be included in
the reset offset process. In `reset-
offsets` case, partitions can be
specified using this format: `topic1:
0,1,2`, where 0,1,2 are the
partition to be included in the
process. Reset-offsets also supports
multiple topic inputs.
--type [String] When specified with '--list', it
displays the types of all the
groups. It can also be used to list
groups with specific types.
Example: --bootstrap-server localhost:
9092 --list --type classic,consumer
This option may be used with the '--
list' option only.
--validate-regex <String: regex> Validate that the syntax of the
provided regular expression is valid
according to the RE2 format.
--verbose Provide additional information, if
any, when describing the group. This
option may be used with '--
offsets'/'--members'/'--state' and
'--bootstrap-server' options only.
Example: --bootstrap-server localhost:
9092 --describe --group group1 --
members --verbose
--version Display Kafka version.
