Fluent Bit

Setting up Fluent Bit is very straightforward:

1. Install Fluent Bit on your server according to the guidelines.

2. Install and set up Fluent Bit input plugins to suit your needs (e.g., Syslog).

3. Modify the Fluent Bit [OUTPUT] configuration to start sending logs to your Logtail source. A basic configuration that forwards logs from all inputs to a single Logtail source could look like this:

/etc/td-agent-bit/td-agent-bit.conf
[SERVICE]
    flush  1
​
[INPUT]
    name tail
    path /var/log/syslog
  
[OUTPUT]
    name    http
    match   *
    tls     On
    host    in.logtail.com
    port    443
    uri     /
    header  Authorization Bearer YOUR_LOGTAIL_SOURCE_TOKEN
    header  Content-Type application/msgpack
    format  msgpack
    retry_limit 5

You can learn more about Fluent Bit configuration from the official manual.

4. Once you're happy with the configuration restart the Fluent Bit service:

sudo service td-agent-bit restart

You should start seeing your logs in Logtail 🎉
