How do I configure filters in Fluentd?

To configure filters in Fluentd, you need to define filter plugins in your configuration file. What specific filter are you looking to set up?

I want to filter out specific log levels, like debug and info.

You can use the filter directive with the grep plugin. Here's an example:

<filter your.log>
  @type grep
  <regexp>
    key log
    pattern /error/  # Only keep error logs
  </regexp>
</filter>

This will filter out all logs except those containing 'error'.

Can I use multiple patterns in the same filter?

Yes, you can use multiple patterns by adding more <regexp> blocks or using the pattern option with a regex that includes all desired levels.

Thanks! Where can I find more examples?

You can check the Fluentd documentation for more examples and detailed explanations on filter configurations.
