How Diagtool works for Fluent Bit
Fluentd and Fluent Bit have similar concepts, both have pluggable input and output modules and data process functions, however the format of configuration is not same. Diatool version 1.0 was released and now Diagtool is able to interpret the configuration of Fluent Bit and gather/validate required information as well as Fluentd. The new option ‘—type/-t‘ enables you to switch Fluentd and Fluent Bit. Here is sample usage of Diagtool for Fluent Bit.
Run Pre-Check
Before running the main function of Diagtool, we recommend you to run precheck with ‘-t’ option to make sure if Diagtool could work in your environment. When you run td-agent-bit packaged Fluent Bit, the configuration information is stored under ‘/etc/td-agent-bit‘ directory and the log information is stored in ‘stdout’. When you build Fluent Bit from source code, you can specify the configuration file path with ‘-c‘ and the log file path with ‘-l’ option respectively.
Run Diagtool
Once the pre-check is completed, you are ready to run the tool. When you use Fluent Bit, please specify the ‘fluentbit‘ in ‘-t‘ option as well as pre-check.
