Types

type ConsoleEncoder 

type ConsoleEncoder struct {
	zapcore.Encoder `json:"-"`
	LogEncoderConfig
}

ConsoleEncoder encodes log entries that are mostly human-readable.

func (ConsoleEncoder) CaddyModule 

func (ConsoleEncoder) CaddyModule() caddy.ModuleInfo

CaddyModule returns the Caddy module information.

func (*ConsoleEncoder) Provision 

func (ce *ConsoleEncoder) Provision(_ caddy.Context) error

Provision sets up the encoder.

func (*ConsoleEncoder) UnmarshalCaddyfile 

func (ce *ConsoleEncoder) UnmarshalCaddyfile(d *caddyfile.Dispenser) error

UnmarshalCaddyfile sets up the module from Caddyfile tokens. Syntax: 

console {
    <common encoder config subdirectives...>
}

See the godoc on the LogEncoderConfig type for the syntax of subdirectives that are common to most/all encoders.

type CookieFilter 

type CookieFilter struct {
	// A list of actions to apply to the cookies.
	Actions []cookieFilterAction `json:"actions"`
}

CookieFilter is a Caddy log field filter that filters cookies.

This filter updates the logged HTTP header string to remove, replace or hash cookies containing sensitive data. For instance, it can be used to redact any kind of secrets, such as session IDs.

If several actions are configured for the same cookie name, only the first will be applied.

func (CookieFilter) CaddyModule 

func (CookieFilter) CaddyModule() caddy.ModuleInfo

CaddyModule returns the Caddy module information.

func (CookieFilter) Filter 

func (m CookieFilter) Filter(in zapcore.Field) zapcore.Field

Filter filters the input field.

func (*CookieFilter) UnmarshalCaddyfile 

func (m *CookieFilter) UnmarshalCaddyfile(d *caddyfile.Dispenser) error

UnmarshalCaddyfile sets up the module from Caddyfile tokens.

func (*CookieFilter) Validate 

func (f *CookieFilter) Validate() error

Validate checks that action types are correct.

type DeleteFilter 

type DeleteFilter struct{}

DeleteFilter is a Caddy log field filter that deletes the field.

func (DeleteFilter) CaddyModule 

func (DeleteFilter) CaddyModule() caddy.ModuleInfo

CaddyModule returns the Caddy module information.

func (DeleteFilter) Filter 

func (DeleteFilter) Filter(in zapcore.Field) zapcore.Field

Filter filters the input field.

func (DeleteFilter) UnmarshalCaddyfile 

func (DeleteFilter) UnmarshalCaddyfile(d *caddyfile.Dispenser) error

UnmarshalCaddyfile sets up the module from Caddyfile tokens.

type FileWriter 

type FileWriter struct {
	// Filename is the name of the file to write.
	Filename string `json:"filename,omitempty"`

	// Roll toggles log rolling or rotation, which is
	// enabled by default.
	Roll *bool `json:"roll,omitempty"`

	// When a log file reaches approximately this size,
	// it will be rotated.
	RollSizeMB int `json:"roll_size_mb,omitempty"`

	// Whether to compress rolled files. Default: true
	RollCompress *bool `json:"roll_gzip,omitempty"`

	// Whether to use local timestamps in rolled filenames.
	// Default: false
	RollLocalTime bool `json:"roll_local_time,omitempty"`

	// The maximum number of rolled log files to keep.
	// Default: 10
	RollKeep int `json:"roll_keep,omitempty"`

	// How many days to keep rolled log files. Default: 90
	RollKeepDays int `json:"roll_keep_days,omitempty"`
}

FileWriter can write logs to files. By default, log files are rotated ("rolled") when they get large, and old log files get deleted, to ensure that the process does not exhaust disk space.

func (FileWriter) CaddyModule 

func (FileWriter) CaddyModule() caddy.ModuleInfo

CaddyModule returns the Caddy module information.

func (FileWriter) OpenWriter 

func (fw FileWriter) OpenWriter() (io.WriteCloser, error)

OpenWriter opens a new file writer.

func (*FileWriter) Provision 

func (fw *FileWriter) Provision(ctx caddy.Context) error

Provision sets up the module

func (FileWriter) String 

func (fw FileWriter) String() string

func (*FileWriter) UnmarshalCaddyfile 

func (fw *FileWriter) UnmarshalCaddyfile(d *caddyfile.Dispenser) error

UnmarshalCaddyfile sets up the module from Caddyfile tokens. Syntax: 

file <filename> {
    roll_disabled
    roll_size     <size>
    roll_uncompressed
    roll_local_time
    roll_keep     <num>
    roll_keep_for <days>
}

The roll_size value has megabyte resolution. Fractional values are rounded up to the next whole megabyte (MiB).

By default, compression is enabled, but can be turned off by setting the roll_uncompressed option.

The roll_keep_for duration has day resolution. Fractional values are rounded up to the next whole number of days.

If any of the roll_size, roll_keep, or roll_keep_for subdirectives are omitted or set to a zero value, then Caddy's default value for that subdirective is used.

func (FileWriter) WriterKey 

func (fw FileWriter) WriterKey() string

WriterKey returns a unique key representing this fw.

type FilterEncoder 

type FilterEncoder struct {
	// The underlying encoder that actually
	// encodes the log entries. Required.
	WrappedRaw json.RawMessage `json:"wrap,omitempty" caddy:"namespace=caddy.logging.encoders inline_key=format"`

	// A map of field names to their filters. Note that this
	// is not a module map; the keys are field names.
	//
	// Nested fields can be referenced by representing a
	// layer of nesting with `>`. In other words, for an
	// object like `{"a":{"b":0}}`, the inner field can
	// be referenced as `a>b`.
	//
	// The following fields are fundamental to the log and
	// cannot be filtered because they are added by the
	// underlying logging library as special cases: ts,
	// level, logger, and msg.
	FieldsRaw map[string]json.RawMessage `json:"fields,omitempty" caddy:"namespace=caddy.logging.encoders.filter inline_key=filter"`

	Fields map[string]LogFieldFilter `json:"-"`
	// contains filtered or unexported fields
}

FilterEncoder can filter (manipulate) fields on log entries before they are actually encoded by an underlying encoder.
