}

EventV1 represents a decision log event. WARNING: The AST() function for EventV1 must be kept in sync with the struct. Any changes here MUST be reflected in the AST() implementation below.

func (*EventV1) AST

func (e *EventV1) AST() (ast.Value, error)

AST returns the Rego AST representation for a given EventV1 object. This avoids having to round trip through JSON while applying a decision log mask policy to the event.

type Logger

type Logger interface {
	plugins.Plugin

	Log(context.Context, EventV1) error
}

Logger defines the interface for decision logging plugins.

type Plugin

type Plugin struct {
	// contains filtered or unexported fields
}

Plugin implements decision log buffering and uploading.

func Lookup

func Lookup(manager *plugins.Manager) *Plugin

Lookup returns the decision logs plugin registered with the manager.

func New

func New(parsedConfig *Config, manager *plugins.Manager) *Plugin

New returns a new Plugin with the given config.

func (*Plugin) Log

func (p *Plugin) Log(ctx context.Context, decision *server.Info) error

Log appends a decision log event to the buffer for uploading.

func (*Plugin) Reconfigure

func (p *Plugin) Reconfigure(_ context.Context, config interface{})

Reconfigure notifies the plugin with a new configuration.

func (*Plugin) Start

func (p *Plugin) Start(ctx context.Context) error

Start starts the plugin.

func (*Plugin) Stop

func (p *Plugin) Stop(ctx context.Context)

Stop stops the plugin.

func (*Plugin) Trigger

func (p *Plugin) Trigger(ctx context.Context) error

Trigger can be used to control when the plugin attempts to upload a new decision log in manual triggering mode.

func (*Plugin) WithMetrics

func (p *Plugin) WithMetrics(m metrics.Metrics) *Plugin

WithMetrics sets the global metrics provider to be used by the plugin.

type ReportingConfig

type ReportingConfig struct {
	BufferSizeLimitBytes  *int64               `json:"buffer_size_limit_bytes,omitempty"`  // max size of in-memory buffer
	UploadSizeLimitBytes  *int64               `json:"upload_size_limit_bytes,omitempty"`  // max size of upload payload
	MinDelaySeconds       *int64               `json:"min_delay_seconds,omitempty"`        // min amount of time to wait between successful poll attempts
	MaxDelaySeconds       *int64               `json:"max_delay_seconds,omitempty"`        // max amount of time to wait between poll attempts
	MaxDecisionsPerSecond *float64             `json:"max_decisions_per_second,omitempty"` // max number of decision logs to buffer per second
	Trigger               *plugins.TriggerMode `json:"trigger,omitempty"`                  // trigger mode
}

ReportingConfig represents configuration for the plugin's reporting behaviour.
