Functions

func IsPartialScrapeError

func IsPartialScrapeError(err error) bool

IsPartialScrapeError checks if an error was wrapped with PartialScrapeError.

Types

type PartialScrapeError

type PartialScrapeError struct {
	Failed int
	// contains filtered or unexported fields
}

PartialScrapeError is an error to represent that a subset of metrics were failed to be scraped.

func NewPartialScrapeError

func NewPartialScrapeError(err error, failed int) PartialScrapeError

NewPartialScrapeError creates PartialScrapeError for failed metrics. Use this error type only when a subset of data was failed to be scraped.

type ScrapeErrors

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

ScrapeErrors contains multiple PartialScrapeErrors and can also contain generic errors.

func (*ScrapeErrors) Add

func (s *ScrapeErrors) Add(err error)

Add adds a regular error.

func (*ScrapeErrors) AddPartial

func (s *ScrapeErrors) AddPartial(failed int, err error)

AddPartial adds a PartialScrapeError with the provided failed count and error.

func (*ScrapeErrors) Combine

func (s *ScrapeErrors) Combine() error

Combine converts a slice of errors into one error. It will return a PartialScrapeError if at least one error in the slice is a PartialScrapeError.
