Best Practices

• Use source directives for each log input (tail, forward, http)
• Apply filter directives for parsing, enrichment, and transformation
• Configure buffer settings for reliable delivery (file buffer, flush intervals)
• Use tag-based routing with match directives and wildcards
• Set pos_file for tail inputs to track read positions
• Enable retry with exponential backoff for output plugins
• Use record_transformer filter for adding metadata fields
• Every tail source must define a pos_file for position tracking
• Use file-based buffers for reliable delivery in production
• Apply filters before match directives in the pipeline
• Set retry configuration for all output plugins
