Types

type Arguments

type Arguments struct {
	Targets             []discovery.Target  `alloy:"targets,attr"`
	ForwardTo           []loki.LogsReceiver `alloy:"forward_to,attr"`
	Encoding            string              `alloy:"encoding,attr,optional"`
	DecompressionConfig DecompressionConfig `alloy:"decompression,block,optional"`
	FileWatch           FileWatch           `alloy:"file_watch,block,optional"`
	TailFromEnd         bool                `alloy:"tail_from_end,attr,optional"`
	LegacyPositionsFile string              `alloy:"legacy_positions_file,attr,optional"`
}

Arguments holds values which are used to configure the loki.source.file component.

func (*Arguments) SetToDefault

func (a *Arguments) SetToDefault()

SetToDefault implements syntax.Defaulter.

type Component

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

Component implements the loki.source.file component.

func New

func New(o component.Options, args Arguments) (*Component, error)

New creates a new loki.source.file component.

func (*Component) DebugInfo

func (c *Component) DebugInfo() interface{}

DebugInfo returns information about the status of tailed targets. TODO(@tpaschalis) Decorate with more debug information once it's made available, such as the last time a log line was read.

func (*Component) Run

func (c *Component) Run(ctx context.Context) error

Run implements component.Component. TODO(@tpaschalis). Should we periodically re-check? What happens if a target comes alive _after_ it's been passed to us and we never receive another Update()? Or should it be a responsibility of the discovery component?

func (*Component) Update

func (c *Component) Update(args component.Arguments) error

Update implements component.Component.

type CompressionFormat

type CompressionFormat string

func (CompressionFormat) MarshalText

func (ut CompressionFormat) MarshalText() (text []byte, err error)

MarshalText implements encoding.TextMarshaler.

func (CompressionFormat) String

func (ut CompressionFormat) String() string

func (*CompressionFormat) UnmarshalText

func (ut *CompressionFormat) UnmarshalText(text []byte) error

UnmarshalText implements encoding.TextUnmarshaler.

type DecompressionConfig

type DecompressionConfig struct {
	Enabled      bool              `alloy:"enabled,attr"`
	InitialDelay time.Duration     `alloy:"initial_delay,attr,optional"`
	Format       CompressionFormat `alloy:"format,attr"`
}

type FileWatch

type FileWatch struct {
	MinPollFrequency time.Duration `alloy:"min_poll_frequency,attr,optional"`
	MaxPollFrequency time.Duration `alloy:"max_poll_frequency,attr,optional"`
}
