1.1、列出所有的消费者组

clike 复制代码
[root@localhost ~]# kafka-consumer-groups.sh --bootstrap-server 192.168.74.148:9092 --list
my_group2
my_group1

1.2、查看 my_group1 组的详细信息

clike 复制代码
[root@localhost ~]# kafka-consumer-groups.sh --bootstrap-server 192.168.74.148:9092 --group my_group1 --describe

                                          option may be used with '--describe' 
                                          and '--bootstrap-server' options     
                                          only.                                
                                        Example: --bootstrap-server localhost: 
                                          9092 --describe --group group1 --

                                          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-period, --to-earliest, --to-    
                                          latest, --shift-by, --from-file, --  
                                          to-current.                          
                                        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: 5000)       
--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.               
--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 --
