Following is the default parser for bro.
{
"parserClassName":"org.apache.metron.parsers.bro.BasicBroParser",
"filterClassName":null,
"sensorTopic":"bro",
"outputTopic":null,
"errorTopic":null,

"stormConfig":{

"parserConfig":{

"fieldTransformations":[

"cacheConfig":{

"rawMessageStrategy":"DEFAULT",

}
