| 19 | b. pipeline.yaml:Sample pipeline.yaml file with minimum source and sink information tags, |
| 20 | c. pipeline.py: Does validation of pipeline.yaml configuration. |
| 21 | d. pipeline_agent.py: Main file of the module while will listen on Rabbitmq exchange "pubsub" |
| 22 | e. pipeline_agent.conf : Conf file should consist of the following information: |
| 23 | i.Rabbitmq server datails(host,port,username,passwd) |

| 28 | 3.To run the module: |
| 29 | ->sudo python pipeline_agent.py |
| 30 | |
| 31 | 4.Format to send conf msg to the module: |
| 32 | i.For updating conf : |
| 33 | -> msg={"sub_info":sub_info,"target":target,"action":"ADD"} |
| 34 | ii.for deleting conf : |
| 35 | -> msg={"sub_info":sub_info,"target":target,"action":"DEL"} |
| 36 | |
| 37 | The above two msgs should be in json fomrat and should send to same rabbitmq-server where pipeline_agent.py is running |
| 38 | with "pubsub" exchage. |
| 39 | ex: |
| 40 | sub_info = ["cpu_util", "memory"] |
| 41 | target = "kafka://1.2.3.2:18" |
