Beats platform hosts various single-purpose data shippers which can be used as lightweight agents after installation to send collected data from hundreds or thousands of machines to the target.
Beats offers a wide variety of shippers, and you can download the one which best suits your needs. This document uses Filebeat, a lightweight log shipper, as an example to describe how to connect Filebeat to CKafka and handle common problems that may occur after the connection.
Follow the steps below to configure the monitoring file:
#======= Filebeat prospectors ==========
filebeat.prospectors:
- input_type: log
# This is the path to the monitoring file.

If you need to configure SALS/PLAINTEXT, you need to set the username and password under Kafka configuration.
# The following parameters need to be configured for SASL. If SASL is not required, skip them.
username: "instance-will#user"
password: "password"
The Filebeat log file (default path: /var/log/filebeat/filebeat
) contains a large number of INFO logs as follows:

This problem may be related to the Filebeat version. Products in the Elastic family are updated frequently, and major version incompatibility problems often occur.
For example, by default, Filebeat 6.5.x runs against Kafka 0.9, 0.10, 1.1.0, or 2.0.0, while Filebeat 5.6.x runs against Kafka 0.8.2.0.
Check the version configuration in the configuration file:
output.kafka:
version:0.10.2 //Set the value to the open-source version of the CKafka instance.
