Types

type DateParser

type DateParser interface {
	ParseTimestamp(log string) (time.Time, string, bool) // Parse timestamp should have the implementation for parsing the timestamp from a log line
}

DateParser is an interface for parsing the timestamp from a log line It returns the datetime, the log line, and a boolean indicating if the datetime was found

func NewDayMonthParser

func NewDayMonthParser(datetimeRegex string, layout string, opts ...DayMonthOption) DateParser

type Dateformat

type Dateformat struct {
	DateRegex  string
	Layout     string
	DateSuffix string
}

type DayMonthOption

type DayMonthOption func(*dayMonthOptions)

func WithInnerDateRegex

func WithInnerDateRegex(regex string) DayMonthOption

func WithStripOuterDate

func WithStripOuterDate() DayMonthOption

func WithTimezone

func WithTimezone(timezone string) DayMonthOption

func WithYear

func WithYear(year string) DayMonthOption

type DayMonthParser

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

DayMonthParser will parse a timestamp string without a year and timezone into a datetime given the regex and layout of the timestamp. It will also optionally strip the outer date and detect if the remaining text contains a valid date

func (*DayMonthParser) ParseTimestamp

func (d *DayMonthParser) ParseTimestamp(log string) (time.Time, string, bool)

type DockerParser

type DockerParser struct {
	TimestampRegex string
}

DockerParser will parse logs with a default ISO8601 timestamp. It is expected that there will be two timestamps

func (*DockerParser) ParseTimestamp

func (p *DockerParser) ParseTimestamp(log string) (time.Time, string, bool)

type EtcdJSONLog

type EtcdJSONLog struct {
	LogLevel  string `json:"level,omitempty"`
	Timestamp string `json:"ts,omitempty"`
	Message   string `json:"msg,omitempty"`
}

type LogType

type LogType string

const (
	LogTypeControlplane LogType = "controlplane"
	LogTypeRancher      LogType = "rancher"
)

type MultipleParser

type MultipleParser struct {
	Dateformats      []Dateformat
	StripLeadingDate bool
}

Multiple parser will parse logs with multiple date formats and optionally strip the leading date.

func (*MultipleParser) ParseTimestamp

func (p *MultipleParser) ParseTimestamp(log string) (time.Time, string, bool)

type RKE2EtcdParser

type RKE2EtcdParser struct{}

RKE2EtcdParser will parse etcd logs for RKE2. These logs can either be in json or plain text.

func (RKE2EtcdParser) ParseTimestamp

func (r RKE2EtcdParser) ParseTimestamp(log string) (time.Time, string, bool)
