Fluent Bit

Logs

Fluent Bit is an open source collector for telemetry data from multiple sources. It can filter, buffer and transform the data before forwarding to one or more destinations.

Install Integration

Command Line Example

Example command line configuration to send CPU metrics from Fluent Bit running in a Docker container to logstash:

docker run -it fluent/fluent-bit:3.1.9 /fluent-bit/bin/fluent-bit -i cpu -o tcp://@logstash.host:@logstash.sslPort -p format=json_lines -p tls=on -p json_date_format=iso8601 -p json_date_key=@timestamp

Example Output Config

If you are using a configuration file (e.g. fluent-bit.conf), rather than specifying in the command line, you can specify the output below to send data to your Logit.io stack:

[OUTPUT]
    Name http
    Match *
    Host @logstash.host
    Port @logstash.sslPort
    tls On
    Format json_lines
    json_date_format iso8601
    json_date_key @timestamp

and run the Docker container with the following command which will mount the configuration file to the container and then run Fluent Bit with the configuration file:

docker run -v /path/to/your/fluent-bit.conf:/fluent-bit/etc/fluent-bit.conf -it fluent/fluent-bit:3.1.9 /fluent-bit/bin/fluent-bit -c /fluent-bit/etc/fluent-bit.conf
