A SampleValue is a representation of a value for a given sample at a given time.

A LabelName is a key for a LabelSet or Metric. It has a value associated therewith.

A LabelValue is an associated value for a LabelName.

A Metric is similar to a LabelSet, but the key difference is that a Metric is a singleton and refers to one and only one stream of samples.

Time is the number of milliseconds since the epoch (1970-01-01 00:00 UTC) excluding leap seconds.

Fingerprint provides a hash-capable representation of a Metric. For our purposes, FNV-1A 64-bit is used.

A LabelSet is a collection of LabelName and LabelValue pairs. The LabelSet may be fully-qualified down to the point where it may resolve to a single

Secret special type for storing secrets.

Duration wraps time.Duration. It is used to parse the custom duration format from YAML. This type should not propagate beyond the scope of input/outpu

LabelNames is a sortable LabelName slice. In implements sort.Interface.

MetricType represents metric type values.

For internal use, so that we can use the sort interface

Structure to represent a clause in an HTTP Accept Header

Alert is a generic representation of an alert in the Prometheus eco-system.

Alert is a list of alerts that can be sorted in chronological order.

AllowedFormat is a settable identifier for the output format that the logger can have.

AllowedLevel is a settable identifier for the minimum level a log entry must be have.

Authorization contains HTTP authorization credentials.

BasicAuth contains basic HTTP authentication credentials.

Closer is implemented by Encoders that need to be closed to finalize encoding. (For example, OpenMetrics needs a final `# EOF` line.) Note that all E

Config is a struct containing configurable settings for the logger

DecodeOptions contains options used by the Decoder and in sample extraction.

Decoder types decode an input stream into metric families.

DialContextFunc defines the signature of the DialContext() function implemented by net.Dialer.

DirectorySetter is a config type that contains file paths that may be relative to the file containing the config.

Encoder types encode metric families into an underlying wire protocol.

FingerprintSet is a set of Fingerprints.

Fingerprints represents a collection of Fingerprint subject to a given natural sorting scheme. It implements sort.Interface.

Format specifies the HTTP content type of the different wire protocols.

HTTPClientConfig configures an HTTP client.

HTTPClientOption defines an option that can be applied to the HTTP client.

Interval describes an interval between two timestamps.

LabelPair pairs a name with a value.

LabelPairs is a sortable slice of LabelPair pointers. It implements sort.Interface.

LabelValues is a sortable LabelValue slice. It implements sort.Interface.

Matcher describes a matches the value of a given label.

Matrix is a list of time series.

OAuth2 is the oauth2 client configuration.

ParseError signals errors while parsing the simple and flat text-based exchange format.

Router wraps httprouter.Router and adds support for prefixed sub-routers, per-request context injections and instrumentation.

Sample is a sample pair associated with a metric. A single sample must either define Value or Histogram but not both. Histogram == nil implies the Val

SampleDecoder wraps a Decoder to extract samples from the metric families decoded by the wrapped Decoder.

SamplePair pairs a SampleValue with a Timestamp.

SampleStream is a stream of Values belonging to an attached COWMetric.

Samples is a sortable Sample slice. It implements sort.Interface.

Scalar is a scalar value evaluated at the set timestamp.

SigV4Config is the configuration for signing remote write requests with AWS's SigV4 verification process. Empty values will be retrieved using the AWS

Silence defines the representation of a silence definition in the Prometheus eco-system.

String is a string value evaluated at the set timestamp.

TLSConfig configures the options for TLS connections.

TextParser is used to parse the simple and flat text-based exchange format. Its zero value is ready to use.

URL is a custom URL type that allows validation at configuration load time.

Value is a generic interface for values resulting from a query evaluation.

Vector is basically only an alias for Samples, but the contract is that in a Vector, all Samples have the same timestamp.

enhancedWriter has all the enhanced write functions needed here. bufio.Writer implements it.

protoDecoder implements the Decoder interface for protocol buffers.

A stateFn is a function that represents a state in a state machine. By executing it, the state is progressed to the next state. The stateFn returns an

textDecoder implements the Decoder interface for the text protocol.

tlsRoundTripper is a RoundTripper that updates automatically its TLS configuration whenever the content of the CA file changes.
