KAFKA MONITORING NOTES 

Q: What is HTTP Event Collector?

The Splunk HTTP Event collector is really pretty straight forward and you can find a lot of documentation online that would explain how it works much better than I can.  It’s just an alternate way of getting data into Splunk rather than the usual means (forwarder).  It’s basically just a listener that accepts raw or JSON data and sends it along to an index.

BACKGROUND

1. What is kafka-splunk-connect?

Splunk Connect for Kafka is a Kafka Connect Sink for Splunk with the following features:

• Data ingestion from Kafka topics into Splunk via Splunk HTTP Event Collector(HEC).
• In-flight data transformation and enrichment.

2. How do we install it ?

  https://github.com/splunk/kafka-connect-splunk

For Installation, we Need access to :

• Kafka hosts that need to be monitored
• SPLUNK DEV-STL instance access
• connect-distributed.properties file
• bootstrap.servers and plugin.path
• which is available for download

INFRASTRUCTURE

Q: Which SPLUNK instance is used for monitoring ?

access to any data for this POC will be through the MSE dev instance:

Q: What do we set values for “bootstrap.servers” and “plugin.path” in connect-distributed.properties file?

bootstrap.servers = kafka broker

plugin.path =  install directory of your Kafka Connect Sink and Source Connectors = place the jar file here for installation

Q: Where do we install the connector jar ?

the jar needs to be installed and configured on the Kafka host(s) per the instructions on Splunk/Github

Place the jar under “plugin.path” directory

Q: How do we start the connector?

.$KAFKA_HOME/bin/connect-distributed.sh $KAFKA_HOME/config/connect-distributed.properties

Q: How do we create connector task?

Run the following curl command for host = nc3-001b-ixb-sp and port = 8088 and below token

curl localhost:8083/connectors -X POST -H "Content-Type: application/json" -d '{

    "name": "kafka-connect-splunk",

    "config": {

      "connector.class": "com.splunk.kafka.connect.SplunkSinkConnector",

      "tasks.max": "3",
