Functions

func Module

func Module() fxutil.Module

Module defines the fx options for this component.

Types

type Component

type Component interface {
	Get() *NetflowConfig
}

Component is the component type.

type ListenerConfig

type ListenerConfig struct {
	FlowType  common.FlowType `mapstructure:"flow_type"`
	Port      uint16          `mapstructure:"port"`
	BindHost  string          `mapstructure:"bind_host"`
	Workers   int             `mapstructure:"workers"`
	Namespace string          `mapstructure:"namespace"`
	Mapping   []Mapping       `mapstructure:"mapping"`
}

ListenerConfig contains configuration for a single flow listener

func (*ListenerConfig) Addr

func (c *ListenerConfig) Addr() string

Addr returns the host:port address to listen on.

type Mapping

type Mapping struct {
	Field       uint16            `mapstructure:"field"`
	Destination string            `mapstructure:"destination"`
	Endian      common.EndianType `mapstructure:"endianness"`
	Type        common.FieldType  `mapstructure:"type"`
}

Mapping contains configuration for a Netflow/IPFIX field mapping

type NetflowConfig

type NetflowConfig struct {
	Enabled                       bool             `mapstructure:"enabled"`
	Listeners                     []ListenerConfig `mapstructure:"listeners"`
	StopTimeout                   int              `mapstructure:"stop_timeout"`
	AggregatorBufferSize          int              `mapstructure:"aggregator_buffer_size"`
	AggregatorFlushInterval       int              `mapstructure:"aggregator_flush_interval"`
	AggregatorFlowContextTTL      int              `mapstructure:"aggregator_flow_context_ttl"`
	AggregatorPortRollupThreshold int              `mapstructure:"aggregator_port_rollup_threshold"`
	AggregatorPortRollupDisabled  bool             `mapstructure:"aggregator_port_rollup_disabled"`

	// AggregatorRollupTrackerRefreshInterval is useful to speed up testing to avoid wait for 1h default
	AggregatorRollupTrackerRefreshInterval uint `mapstructure:"aggregator_rollup_tracker_refresh_interval"`

	PrometheusListenerAddress string `mapstructure:"prometheus_listener_address"` // Example `localhost:9090`
	PrometheusListenerEnabled bool   `mapstructure:"prometheus_listener_enabled"`
}

NetflowConfig contains configuration for NetFlow collector.

func ReadConfig

func ReadConfig(conf config.Component, logger log.Component) (*NetflowConfig, error)

ReadConfig builds and returns configuration from Agent configuration.

func (*NetflowConfig) SetDefaults

func (mainConfig *NetflowConfig) SetDefaults(namespace string, logger log.Component) error

SetDefaults sets default values wherever possible, returning an error if any values are malformed.
