Used in: Histogram

• uint64 cumulative_count = 1

  Cumulative in increasing order.

• double cumulative_count_float = 4

  Overrides cumulative_count if > 0.

• double upper_bound = 2

  Inclusive.

• optional Exemplar exemplar = 3

A BucketSpan defines a number of consecutive buckets in a native histogram with their offset. Logically, it would be more straightforward to include the bucket counts in the Span. However, the protobuf representation is more compact in the way the data is structured here (with all the buckets in a single array separate from the Spans).

Used in: Histogram

• sint32 offset = 1

  Gap to previous span, or starting point for 1st span (which can be negative).

• uint32 length = 2

  Length of consecutive buckets.

Used in: Metric

• double value = 1

• optional Exemplar exemplar = 2

Used in: Bucket, Counter

• repeated LabelPair label = 1

  [(gogoproto.nullable) = false];

• double value = 2

• optional google.protobuf.Timestamp timestamp = 3

  OpenMetrics-style.

Used in: Metric

• double value = 1

Used in: Metric

• uint64 sample_count = 1

• double sample_count_float = 4

  Overrides sample_count if > 0.

• double sample_sum = 2

• repeated Bucket bucket = 3

  Buckets for the conventional histogram.

  [(gogoproto.nullable) = false]; // Ordered in increasing order of upper_bound, +Inf bucket is optional.

• sint32 schema = 5

  schema defines the bucket schema. Currently, valid numbers are -4 <= n <= 8. They are all for base-2 bucket schemas, where 1 is a bucket boundary in each case, and then each power of two is divided into 2^n logarithmic buckets. Or in other words, each bucket boundary is the previous boundary times 2^(2^-n). In the future, more bucket schemas may be added using numbers < -4 or > 8.

• double zero_threshold = 6

  Breadth of the zero bucket.

• uint64 zero_count = 7

  Count in zero bucket.

• double zero_count_float = 8

  Overrides sb_zero_count if > 0.

• repeated BucketSpan negative_span = 9

  Negative buckets for the native histogram.

  [(gogoproto.nullable) = false];

• repeated sint64 negative_delta = 10

  Use either "negative_delta" or "negative_count", the former for regular histograms with integer counts, the latter for float histograms.

  Count delta of each bucket compared to previous one (or to zero for 1st bucket).

• repeated double negative_count = 11

  Absolute count of each bucket.

• repeated BucketSpan positive_span = 12

  Positive buckets for the native histogram.

  [(gogoproto.nullable) = false];

• repeated sint64 positive_delta = 13

  Use either "positive_delta" or "positive_count", the former for regular histograms with integer counts, the latter for float histograms.

  Count delta of each bucket compared to previous one (or to zero for 1st bucket).

• repeated double positive_count = 14

  Absolute count of each bucket.
