In your Fluent Bit configuration file (fluent-bit.conf by default), add Logz.io as an output.

Note: Logz.io-Out Plugin for Fluent Bit supports one output stream to Logz.io. We plan to add support for multiple streams in the future.
In the meantime, we recommend running a new instance for each output stream you need.

For a list of options, see the configuration parameters below to add to the code block. 👇

[OUTPUT]
    Name  logzio
    Match *
    Workers 1
    logzio_token <<SHIPPING-TOKEN>>
    logzio_url   https://<<LISTENER-HOST>>:8071
    id <<any string>>

3. Run Fluent Bit with the Logz.io plugin

fluent-bit -e /fluent-bit/plugins/out_logzio-linux.so \
-c /fluent-bit/etc/fluent-bit.conf

4. Check Logz.io for your logs

Give your logs some time to get from your system to ours, and then open Kibana.

If you still don't see your logs, see log shipping troubleshooting.
