compare encodes both provided slices of metric families into the text format, compares their string message, and returns an error if they do not match

ContentTypeHeader returns content type header value for the given proto message or empty string for unknown proto message.

deleteByHashWithLabelValues removes the metric from the hash bucket h. If there are multiple matches in the bucket, use lvs to select a metric and rem

deleteByHashWithLabels removes the metric from the hash bucket h. If there are multiple matches in the bucket, use lvs to select a metric and remove o

deleteByLabels deletes a metric if the given labels are present in the metric.

doubleBucketWidth doubles the bucket width (by decrementing the schema number). Note that very sparse buckets could lead to a low reduction of the buc

encodeComponent encodes the provided string with base64.RawURLEncoding in case it contains '/' and as "=" in case it is empty. If neither is the case,

exactSumFor takes a runtime/metrics metric name (that is assumed to be of kind KindFloat64Histogram) and returns its exact sum and whether its exact s

Find longest matching block in a[alo:ahi] and b[blo:bhi]. If IsJunk is not defined: Return (i,j,k) such that a[i:i+k] is equal to b[j:j+k], where

findMetricWithPartialLabel returns the index of the matching metric or len(metrics) if not found.

Convert range to the "ed" format

getMetricWithHashAndLabelValues gets a metric while handling possible collisions in the hash space. Must be called while holding the read mutex.

getMetricWithHashAndLabels gets a metric while handling possible collisions in the hash space. Must be called while holding read mutex.

getOrCreateMetricWithLabelValues retrieves the metric by hash and label value or creates it and returns the new one. This function holds the mutex.

getOrCreateMetricWithLabels retrieves the metric by hash and label value or creates it and returns the new one. This function holds the mutex.

getRuntimeNumThreads returns the number of open OS threads.

httpError removes any content-encoding header and then calls http.Error with the provided error and http.StatusInternalServerError. Error contents is

indexOf searches the given slice of strings for the target string and returns the index or len(items) as well as a boolean whether the search succeede

limitBuckets applies a strategy to limit the number of populated sparse buckets. It's generally best effort, and there are situations where the number

lint is the entry point for linting a single metric.

marshalHistogram writes something like: { "count": "42", "sum": "34593.34", "buckets": [ [ 3, "-0.25", "0.25", "3"], [

marshalHistogramBucket writes something like: [ 3, "-0.25", "0.25", "3"] See marshalHistogram to understand what the numbers mean

matchPartialLabels searches the current metric and returns whether all of the target label:value pairs are present.

maybeReset resets the whole histogram if at least h.nativeHistogramMinResetDuration has been passed. It returns true if the histogram has been reset.

rotateStreams needs mtx AND bufMtx locked.

maybeWidenZeroBucket widens the zero bucket until it includes the existing buckets closest to the zero bucket (which could be two, if an equidistant n

metricUnits attempts to detect known unit types used as part of a metric name, e.g. "foo_bytes_total" or "bar_baz_milligrams".

newBatchHistogram creates a new batch histogram value with the given Desc, buckets, and whether or not it has an exact sum available. buckets must al

newNativeHistogramWithClassicBuckets returns a Metric representing a native histogram that also has classic buckets. This is for testing purposes.

newProblem is helper function to create a Problem.

parseWriteResponseStats returns WriteResponseStats parsed from the response headers. As per 2.0 spec, missing header means 0. However, abrupt HTTP er

processMetric is an internal helper method only used by the Gather method.

reBucketExp takes a list of bucket boundaries (lower bound inclusive) and downsamples the buckets to those a multiple of base apart. The end result is

releaseFunc returns the done callback for one caller sharing cy. When the last caller releases, the underlying done is invoked and the cycle is cleare
