I am new to elasticsearch. I need to send bulk data to elasticsearch using log4j2. I didn't find any proper information on the internet for this. Even some informative article would be a great help. Thanks in advance.
NoSql Log4j2 appender logs messages to Elasticsearch.

We are planning to store our (Spring-Boot) application logs to ElasticSearch. I am aware of ELK stack, which uses FileBeat + LogStash to collect and process the logs.
What is desired: Have an appender in logback.xml to directly send the logs to ElasticSearch. The very basic idea is of having an appender like File-Appenders with the difference of target for storing logs being ElasticSearch. At the same time, we want to do it in asynchronous manner. FYI, we are using slf4j with logback implementations for logging.
More specifically: We want to remove the intermediators:: Logstash or Beats as they will need more infra and may bring unwanted overhead. And having the process of sending logs to ElasticSearch in asynchronous way would be really great (so that application does not suffer latency due to logging).
What I have already tried:
Send Spring Boot logs directly to LogStash. But it seems of not much use, since it internally uses file appenders and the logs are then sent to LogStash.
Is there any such appenders available? Or maybe there is some workaround.
I am looking for an example how on how to send Micronaut's metric to elastic search, it does not look like it is supported out of the box ?
Thank you, kindly

Micronaut 1.2.0 will include support for Elastic as a backend for the metrics using Micrometer.
From https://docs.micronaut.io/snapshot/guide/index.html#_micronaut_micrometer_1_2_update
Meter registry support for AppOptics, Azure Monitor, Datadog, Dynatrace, Elastic, Ganglia, Humio, Influx, Jmx, Kairos, New Relic, SignalFX, Stackdriver and Wavefront
Keep in mind that this is not included in 1.2.0.RC1 but it will be available in 1.2.0.RC2.
I am looking for the light-weight log shipper which can directly transfer my logs to elasticsearch from kafka. Out of Filebeat, Logagent, Logstash(but i need light weighted) which among them or others can suites my use-case the best?
rsyslog is lightweight. As from version 8.27, it supports kafka as input. Elasticsearch as output is supported from even earlier.
Kafka input module configuration is described here
Elasticsearch output module configuration is described here
Question for Kafka experts:
Anyone knows how to get worker's config setting 'bootstrap.servers' either from SinkConnector or SinkTask? Or how to get Kafka cluster information from connector?
Thank you
AFAIK, the Connect API doesn't provide this information right now.
If you need this functionality, perhaps your best bet is to open a JIRA on the Apache Kafka project and explain the use-case (i.e. what are you planning on doing this information).
I'm looking to consume from Kafka and save data into Hadoop and Elasticsearch.
I've seen 2 ways of doing this currently: using Filebeat to consume from Kafka and send it to ES and using Kafka-Connect framework. There is a Kafka-Connect-HDFS and Kafka-Connect-Elasticsearch module.
I'm not sure which one to use to send streaming data. Though I think that if I want at some point to take data from Kafka and place it into Cassandra I can use a Kafka-Connect module for that but no such feature exists for Filebeat.
Kafka Connect can handle streaming data and is a bit more flexible. If you are just going to elastic, Filebeat is a clean integration for log sources. However, if you are going from Kafka to a number of different sinks, Kafka Connect is probably what you want. I'd recommend checking out the connector hub to see some examples of open source connectors at your disposal currently http://www.confluent.io/product/connectors/
