syslog.bolt.enriched=true
syslog.bolt.hdfsRoot=hdfs://namenode1:8020
syslog.bolt.csvFilePath=/user/storm/syslogEndpoints.csv
Endopoint Csv File
The format of the file is like:
KEY_extraData-key1,KEY_extraData-key2,host,port,protocol
value11,value12,value13,host-1,5140,tcp
Using the values in extraData, the message will be sent to the specified host, port and protocol
Example
Usin the following endpoints CSV File:
KEY_source_host,KEY_source_type,host,port,protocol
host-1,system,192.168.1.4,5140,tcp
host-2,user,192.168.1.5,5141,udp
The input message:
{
"extraData":{"source_host": "host-1", "source_type": "system", "date": "2015-04-23", "time": "07:16:08"},
"message": "the original body string"
}will be send to 192.168.1.4:5140 using tcp.
