Overview

Package parsers provides an interface for different log parsing engines.

Each module in here takes care of a specific log type, providing any necessary or relevant smarts for that style of logs.

Types

type ExtRegexp

type ExtRegexp struct {
	*regexp.Regexp
}

ExtRegexp is a Regexp with one additional method to make it easier to work with named groups

func (*ExtRegexp) FindStringSubmatchMap

func (r *ExtRegexp) FindStringSubmatchMap(s string) (string, map[string]string)

FindStringSubmatchMap behaves the same as FindStringSubmatch except instead of a list of matches with the names separate, it returns the full match and a map of named submatches

type LineParser

type LineParser interface {
	ParseLine(line string) (map[string]interface{}, error)
}

type Parser

type Parser interface {
	// Init does any initialization necessary for the module
	Init(options interface{}) error
	// ProcessLines consumes log lines from the lines channel and sends log events
	// to the send channel. prefixRegex, if not nil, will be stripped from the
	// line prior to parsing. Any named groups will be added to the event.
	ProcessLines(lines <-chan string, send chan<- event.Event, prefixRegex *ExtRegexp)
}
