The data is sent to Topic “weather”, now we will start logstash and take input from kafka consumer and save to elasticsearch. We will use Elasticsearch 2.3.2 because of compatibility issues described in issue #55 and Kafka 0.10.0. output { elasticsearch { hosts => "localhost:9200" index => "webdb" document_type => "weblog" } } answered Jun 19, 2020 by MD This plugin has been created as a way to ingest data in any database with a JDBC interface into Logstash. input { kafka { bootstrap_servers => ["localhost:9092"] topics => ["rsyslog_logstash"] }} If you need Logstash to listen to multiple topics, you can add all of them in the topics array.

We assume that we already have a logs topic created in Kafka and we would like to send data to an index called logs_index in Elasticsearch. To simplify our test we will use Kafka Console Producer to ingest data into Kafka. The example above is a basic setup of course. Filebeat, Kafka, Logstash, Elasticsearch and Kibana Integration is used for big organizations where applications deployed in production on hundreds/thousands of servers and scattered around different locations and need to do analysis on data from these servers on real time.

Logstash can take input from Kafka to parse data and send parsed output to Kafka for streaming to other Application. Elasticsearch is an open source scalable search engine used for monitoring, alerting, and pattern recognition. We use Kafka 0.10.0 to avoid build issues. Kafka Replaces Logstash in the Classic ELK Workflow In this workflow we use Elasticsearch as our pattern recognition engine and its built-in Kibana as our visualization frontend.

It writes data from a topic in Apache Kafka® to an index in Elasticsearch. The Kafka Connect Elasticsearch Service sink connector moves data from Apache Kafka® to Elasticsearch. This allows an independent evolution of schemas for data from different topics. Kafka, and similar brokers, play a huge part in buffering the data flow so Logstash and Elasticsearch don't cave under the pressure of a sudden burst.
