Splunk logging library Doesn't work

[pmurarka]

I am trying to use Splunk logging library  to log events to HTTP Event Collector via java.util.logging.

Followed steps as mentioned in: https://dev.splunk.com/enterprise/docs/java/logging-java/howtouseloggingjava/enableloghttpjava

Verified the HTPP event collector works fine with below snippet of code from emr cluster and also curl command works fine.

RequestBody formBody = new FormBody.Builder()
        .add("username", "abc")
        .build();

Request request = new Request.Builder()
        .url("http://host:8088/services/collector")
        .addHeader("Authorization", "Splunk token")
        .post(RequestBody.create(MediaType.parse("application/json; profile=urn:splunk:event:1.0; charset=utf-8"),"{\"event\": \"Thursday, world!\", \"sourcetype\": \"manual\"}"))
        .build();

However, I cant get it working through Splunk logging in java. 

Java code:

String jsonMsg = "{\"event\": \"Thursday, world!\", \"sourcetype\": \"manual\"}";


 Logger logger = java.util.logging.Logger.getLogger("splunkLogger");

 logger.info(jsonMsg);

splunk-http-input.properties

# Implicitly create a logger called 'splunkLogger', set its level to INFO, and

# make it log using the SocketHandler.

splunkLogger.level = INFO

handlers = com.splunk.logging.HttpEventCollectorLoggingHandler

# Configure the com.splunk.logging.HttpEventCollectorHandler

com.splunk.logging.HttpEventCollectorLoggingHandler.url = http://host:8088

com.splunk.logging.HttpEventCollectorLoggingHandler.level = INFO

com.splunk.logging.HttpEventCollectorLoggingHandler.token = token

com.splunk.logging.HttpEventCollectorLoggingHandler.batch_size_count = 1

# com.splunk.logging.HttpEventCollectorLoggingHandler.middleware = HttpEventCollectorUnitTestMiddleware

# com.splunk.logging.HttpEventCollectorLoggingHandler.index=default

com.splunk.logging.HttpEventCollectorLoggingHandler.disableCertificateValidation=true

# You would usually use XMLFormatter or SimpleFormatter for this property, but

# SimpleFormatter doesn't accept a format string under Java 6, and so we cannot

# control its output. Thus we use a trivial formatter as part of the test suite

# to make it easy to deal with.

#com.splunk.logging.HttpEventCollectorHandler.Formatter = TestFormatter

Invoking it with command:

java -Djava.util.logging.config.file=/home/ec2-user/splunk-http-input.properties -cp java-project-1.0-SNAPSHOT.jar com.mkyong.hashing.SendEvents

Can someone tell me what I am missing here.

After a lot of debugging I realized it is required to specify the index=main(otherwise it will be empty) . It won’t work without this.

I guess some improvisation can be done to throw proper error as an improvement for error logging.
