var JSON = func() jsoniter.API {
	config := jsoniter.Config{
		EscapeHTML: true,

		ValidateJsonRawMessage: true,

		SortMapKeys: false,
	}
	api := config.Froze()
	rewriteFields := jsonutil.NewEncoderNamingStrategy(RewriteFieldName)
	api.RegisterExtension(rewriteFields)
	return api
}()

JSON is a custom jsoniter config to properly remap field names for compatibility with Athena views

var Validator = validator.New()

Validator can be used to validate schemas of log fields

Types

type LogParser 

type LogParser interface {
	// LogType returns the log type supported by this parser
	LogType() string

	// Parse attempts to parse the provided log line
	// If the provided log is not of the supported type the method returns nil and an error
	Parse(log string) ([]*PantherLog, error)

	// New returns a new instance of the log parser, used like a factory method for stateful parsers
	New() LogParser
}

LogParser represents a parser for a supported log type

type PantherAnyString added in v0.2.0 

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

func NewPantherAnyString added in v0.2.0 

func NewPantherAnyString() *PantherAnyString

func (*PantherAnyString) MarshalJSON added in v0.2.0 

func (any *PantherAnyString) MarshalJSON() ([]byte, error)

func (*PantherAnyString) UnmarshalJSON added in v0.2.0 

func (any *PantherAnyString) UnmarshalJSON(jsonBytes []byte) error

type PantherLog added in v0.2.0 

type PantherLog struct {

	//  required
	PantherLogType   *string            `json:"p_log_type,omitempty" validate:"required" description:"Panther added field with type of log"`
	PantherRowID     *string            `json:"p_row_id,omitempty" validate:"required" description:"Panther added field with unique id (within table)"`
	PantherEventTime *timestamp.RFC3339 `json:"p_event_time,omitempty" validate:"required" description:"Panther added standardize event time (UTC)"`
	PantherParseTime *timestamp.RFC3339 `json:"p_parse_time,omitempty" validate:"required" description:"Panther added standardize log parse time (UTC)"`

	// optional (any)
	PantherAnyIPAddresses  *PantherAnyString `json:"p_any_ip_addresses,omitempty" description:"Panther added field with collection of ip addresses associated with the row"`
	PantherAnyDomainNames  *PantherAnyString `json:"p_any_domain_names,omitempty" description:"Panther added field with collection of domain names associated with the row"`
	PantherAnySHA1Hashes   *PantherAnyString `json:"p_any_sha1_hashes,omitempty" description:"Panther added field with collection of SHA1 hashes associated with the row"`
	PantherAnyMD5Hashes    *PantherAnyString `json:"p_any_md5_hashes,omitempty" description:"Panther added field with collection of MD5 hashes associated with the row"`
	PantherAnySHA256Hashes *PantherAnyString `` /* 144-byte string literal not displayed */
	// contains filtered or unexported fields
}

All log parsers should extend from this to get standardized fields (all prefixed with 'p_' as JSON for uniqueness) NOTE: It is VERY important that fields are added to END of the structure to avoid needed to re-build existing Glue partitions.
