I am using Apache Metron to push Bro logs to the Apache Kafka using the following link (metron-bro-plugin-kafka):

https://github.com/apache/metron-bro-plugin-kafka

I installed Bro on a CentOS VM and able to receive data in Kafka on the server side. The data then send to the Apache Storm. There is a problem inside the Storm which it seems that it cannot parse the received log and cast it to a JSONObject. Short description of the error is as follow:

java.lang.IllegalStateException:
Unable to parse Message:
{"ts":1532184126.429716,"uid":"CIYoFN1y9Q3D2iJVnc","id.orig_h":"192.168.181.130","id.orig_p":49483,"id.resp_h":"192.168.181.2","id.resp_p":53,

The relevant part of the log is as follow:

Do I need to make any change in the parser config? Any help would be appreciated.

drodriguez · ‎10-22-2018

I have this exact same problem.

mustafakmal · ‎11-06-2018

Were you able to solve this? Having the same exact problem

drodriguez · ‎11-06-2018

@Mustafa Akmal

I was able to solve this by adding a simple configuration on local.bro:

redef Kafka::tag_json = T;

mustafakmal · ‎11-06-2018

Hey. Thanks for the help. I added this to the local.bro file but now getting this error.

drodriguez · ‎11-14-2018

Could you share your local.bro?
