Types

type AppendEncoder added in v2.8.0 

type AppendEncoder struct {
	// The underlying encoder that actually encodes the
	// log entries. If not specified, defaults to "json",
	// unless the output is a terminal, in which case
	// it defaults to "console".
	WrappedRaw json.RawMessage `json:"wrap,omitempty" caddy:"namespace=caddy.logging.encoders inline_key=format"`

	// A map of field names to their values. The values
	// can be global placeholders (e.g. env vars), or constants.
	// Note that the encoder does not run as part of an HTTP
	// request context, so request placeholders are not available.
	Fields map[string]any `json:"fields,omitempty"`
	// contains filtered or unexported fields
}

AppendEncoder can be used to add fields to all log entries that pass through it. It is a wrapper around another encoder, which it uses to actually encode the log entries. It is most useful for adding information about the Caddy instance that is producing the log entries, possibly via an environment variable.

    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.

	// The underlying encoder that actually encodes the
	// log entries. If not specified, defaults to "json",

	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
}
