var ErrSkipProcessingData = errors.New("sentinel error to skip processing data from the remainder of the pipeline")

ErrSkipProcessingData is a sentinel value to indicate when traces or metrics should intentionally be dropped from further processing in the pipeline because the data is determined to be irrelevant. A processor can return this error to stop further processing without propagating an error back up the pipeline to logs.

Types

type Action 

type Action string

Action is the enum to capture the four types of actions to perform on an attribute. 

const (
	// INSERT adds the key/value to attributes when the key does not exist.
	// No action is applied to attributes where the key already exists.
	INSERT Action = "insert"

	// UPDATE updates an existing key with a value. No action is applied
	// to attributes where the key does not exist.
	UPDATE Action = "update"

	// UPSERT performs the INSERT or UPDATE action. The key/value is
	// insert to attributes that did not originally have the key. The key/value is
	// updated for attributes where the key already existed.
	UPSERT Action = "upsert"

	// DELETE deletes the attribute. If the key doesn't exist, no action is performed.
	DELETE Action = "delete"

	// HASH calculates the SHA-1 hash of an existing value and overwrites the
	// value with it's SHA-1 hash result.
	HASH Action = "hash"

	// EXTRACT extracts values using a regular expression rule from the input
	// 'key' to target keys specified in the 'rule'. If a target key already
	// exists, it will be overridden.
	EXTRACT Action = "extract"
)

type ActionKeyValue 

type ActionKeyValue struct {
	// Key specifies the attribute to act upon.
	// This is a required field.
	Key string `mapstructure:"key"`

	// Value specifies the value to populate for the key.
	// The type of the value is inferred from the configuration.
	Value interface{} `mapstructure:"value"`

	// A regex pattern  must be specified for the action EXTRACT.
	// It uses the attribute specified by `key' to extract values from
	// The target keys are inferred based on the names of the matcher groups
	// provided and the names will be inferred based on the values of the
	// matcher group.
	// Note: All subexpressions must have a name.
	// Note: The value type of the source key must be a string. If it isn't,
	// no extraction will occur.
	RegexPattern string `mapstructure:"pattern"`

	// FromAttribute specifies the attribute to use to populate
	// the value. If the attribute doesn't exist, no action is performed.
	FromAttribute string `mapstructure:"from_attribute"`

	// Action specifies the type of action to perform.
	// The set of values are {INSERT, UPDATE, UPSERT, DELETE, HASH}.
	// Both lower case and upper case are supported.
	// INSERT -  Inserts the key/value to attributes when the key does not exist.
	//           No action is applied to attributes where the key already exists.
	//           Either Value or FromAttribute must be set.
	// UPDATE -  Updates an existing key with a value. No action is applied
	//           to attributes where the key does not exist.
	//           Either Value or FromAttribute must be set.
	// UPSERT -  Performs insert or update action depending on the attributes
	//           containing the key. The key/value is insert to attributes
	//           that did not originally have the key. The key/value is updated
	//           for attributes where the key already existed.
	//           Either Value or FromAttribute must be set.
	// DELETE  - Deletes the attribute. If the key doesn't exist,
	//           no action is performed.
	// HASH    - Calculates the SHA-1 hash of an existing value and overwrites the
	//           value with it's SHA-1 hash result.
	// EXTRACT - Extracts values using a regular expression rule from the input
	//           'key' to target keys specified in the 'rule'. If a target key
	//           already exists, it will be overridden.
	// This is a required field.
	Action Action `mapstructure:"action"`
}

ActionKeyValue specifies the attribute key to act upon.

type AttrProc 

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

func NewAttrProc 

func NewAttrProc(settings *Settings) (*AttrProc, error)

type LProcessor 

type LProcessor interface {
	// ProcessLogs is a helper function that processes the incoming data and returns the data to be sent to the next component.
	// If error is returned then returned data are ignored. It MUST not call the next component.
	ProcessLogs(context.Context, pdata.Logs) (pdata.Logs, error)
}

LProcessor is a helper interface that allows avoiding implementing all functions in LogsProcessor by using NewLogsProcessor.

type MProcessor
