Sending topbeat events to kafka

(Josh Star Long) #1

Hi all,

I'm trying to send topbeat's events to kafka. This is what I have done so far, download the nightly version with


then installed it with dpkg -i. I'm using the nightly version because that is the version that support kafka integration.

I then configured topbeat as follows

  period: 10

  procs: [".*"]

    system: true

    proc: true

    filesystem: true

    cpu_per_core: false

  ### kafka as output
    # The kafka hosts
    hosts: ["localhost:9092"]

    # kafka topic 
    topic: "toptopic"

  fields_under_root: true
    custom_field: my-custom_field

      pretty: true


    rotateeverybytes: 10485760 # = 10MB

When I try to consume the messages of the topic toptopic, I see nothing inside the topic. I know that the kafka plugin is actaully taken into consideration because when I go to the directory /etc/topbeat and run topbaet in the debug with the command

topbeat -c topbeat.yml  -e -d "*"

I see the follow in the logs

2016/03/31 18:29:34.324604 log.go:16: WARN kafka message: [Initializing new client]

What am I missing.

Any helps will be welcoming.
Thanks very much.

I finally get it working. Knowing that topbeat was supposed to publish its events to kafka, the trick was to remove the tags output

       pretty: true

In the configuration file of topbeat.

Hope this helps someone in the future.
