Fluentd is a data collection and processing tool that supports multiple input sources, data formats, and output destinations. The tool allows you to stream and consolidate logs from different applications into one unified format and send this information to the Gcore Managed Logging.

​
Install Fluentd

Download Fluentd from the official Fluentd website and install it using your preferred method.

​
Configure Fluentd

A standard Fluentd configuration consists of three sections: input, filter, and output. The input and filter sections depend on the sources of logs.

To send logs to Gcore Managed Logging, configure Fluentd with the Kafka Integration Plugin in your Fluentd installation.

1. Configure Fuentd with Kafka output by adding the following data to the fluent.conf file:

<match pattern>
  @type kafka2


  # list of seed brokers
  brokers laas-example.gcore.com:443
  username: username
  password: password
  scram_mechanism: "sha512"
  default_topic: namespace_username.topic_name
  sasl_over_ssl: true


  # buffer settings
  <buffer>
    @type memory
    ## OPTIONAL PARAMS
    timekey: 30s
    timekey_wait: 10s
    timekey_use_utc: true
    chunk_limit_size: 4MB
    total_limit_size: 64MB
    chunk_full_threshold: "0.9"
    queued_chunks_limit_size: 12
    flush_thread_count: 12
  </buffer>


  # data type settings
  <format>
    @type json
  </format>
</match>

2. Customize the highlighted values:

  • brokers: Kafka servers to which logs will be exported

  • username: Your username

  • password: Your password

  • default_topic: Your username and topic name, separated with a dot (.)

Tip

You can find your username, password, and topic name information in the Gcore Customer Portal on the Logging page. Learn more about Managed Logging configuration in our dedicated guide.

3. Save the changes in the Fluentd configuration file.

4. Restart Fluentd. It will start sending logs to the Gcore Managed Logging.
