To visualize log files on multiple machines using Netdata and Fluent Bit, you'll need to set up a data pipeline. Here's a high-level overview of how you can achieve this:

1. Install Fluent Bit on each machine with log files
2. Configure Fluent Bit to collect and parse your log files
3. Set up Netdata on a central server or each machine
4. Configure Fluent Bit to send data to Netdata
5. Configure Netdata to receive and visualize the data from Fluent Bit

Let's break this down into more detailed steps:

1. Install Fluent Bit: Follow the official installation guide for your operating system: https://docs.fluentbit.io/manual/installation/getting-started-with-fluent-bit

2. Configure Fluent Bit: Create a configuration file (usually /etc/fluent-bit/fluent-bit.conf) to collect and parse your log files. Here's a basic example:

   [INPUT]
       Name tail
       Path /path/to/your/logfile.log
       Parser your_log_parser
   
   [PARSER]
       Name your_log_parser
       Format regex
       Regex ^(?<time>[^ ]*) (?<message>.*)$
       Time_Key time
       Time_Format %Y-%m-%d %H:%M:%S
   
   [OUTPUT]
       Name http
       Match *
       Host your_netdata_host
       Port 19999
       URI /api/v1/collector/charts
       Format json_stream
   

   Adjust the Path, Parser, and Regex fields according to your log format.

3. Install Netdata: Follow the official installation guide: https://learn.netdata.cloud/docs/agent/packaging/installer

4. Configure Netdata: Enable the web_log plugin in Netdata by editing /etc/netdata/netdata.conf:

   [web_log]
       enabled = yes
   

5. Start both services:

   sudo systemctl start fluent-bit
   sudo systemctl start netdata
   

Now, Fluent Bit should be collecting your log data and sending it to Netdata, which will visualize it in real-time.

This is a basic setup. Depending on your specific needs, you might want to add more advanced configurations, such as:

• Filtering and transforming log data in Fluent Bit
• Setting up aggregation if you have multiple machines
• Configuring alerting in Netdata
