Documentation

Overview

Package fb provides filebeat-compatible configuration validation for the mito tool. Validation rules mirror the constraints in the filebeat CEL input's config.go and config_auth.go without depending on go-ucfg or any elastic-agent-libs package.

Behaviour under -fb is not covered by semver compatibility guarantees. Validation rules may change between minor releases to track upstream filebeat changes.

Functions

func CheckState

func CheckState(state map[string]any) error

CheckState inspects state data (the -data JSON) and rejects it if it contains a "secret" key at the top level.

Types

type Config

type Config struct {
	Globals       map[string]interface{} `yaml:"globals"`
	Regexps       map[string]string      `yaml:"regexp"`
	XSDs          map[string]string      `yaml:"xsd"`
	Auth          *authConfig            `yaml:"auth"`
	HTTPHeaders   http.Header            `yaml:"http_headers"`
	MaxBodySize   int64                  `yaml:"max_body_size"`
	MaxExecutions *int                   `yaml:"max_executions"`

	Resource    *resourceConfig `yaml:"resource"`
	SecretState map[string]any  `yaml:"secret_state"`
}

Config is the filebeat-compatible configuration for mito. It contains all the fields from rc.Config plus resource, rate limit, and retry sections that filebeat's CEL input expects. Auth field names follow filebeat conventions (user/password, not username/password).

func (*Config) RC

func (c *Config) RC() rc.Config

RC returns the rc.Config subset needed by the mito runtime. Auth is converted from filebeat's field names to the lib types mito uses.

func (*Config) Validate

func (c *Config) Validate() error

Validate checks the configuration against filebeat CEL input constraints. Error messages match filebeat's where possible.
