Distribution

Distribution represents a frequency distribution of double-valued sample points. It contains the size of the population of sample points plus additional optional information:

the arithmetic mean of the samples
the minimum and maximum of the samples
the sum-squared-deviation of the samples, used to compute variance
a histogram of the values of the sample points

Fields
`count`	`int64` The total number of samples in the distribution. Must be >= 0.
`mean`	`double` The arithmetic mean of the samples in the distribution. If `count` is zero then this field must be zero.
`minimum`	`double` The minimum of the population of values. Ignored if `count` is zero.
`maximum`	`double` The maximum of the population of values. Ignored if `count` is zero.
`sum_of_squared_deviation`	`double` The sum of squared deviations from the mean: Sum[i=1..count]((x_i - mean)^2) where each x_i is a sample values. If `count` is zero then this field must be zero, otherwise validation of the request fails.
`bucket_counts[]`	`int64` The number of samples in each histogram bucket. `bucket_counts` are optional. If present, they must sum to the `count` value. The buckets are defined below in `bucket_option`. There are N buckets. `bucket_counts[0]` is the number of samples in the underflow bucket. `bucket_counts[1]` to `bucket_counts[N-1]` are the numbers of samples in each of the finite buckets. And `bucket_counts[N] is the number of samples in the overflow bucket. See the comments of`bucket_option` below for more details. Any suffix of trailing zeros may be omitted.
`exemplars[]`	`Exemplar` Example points. Must be in increasing order of `value` field.
Union field `bucket_option`. Defines the buckets in the histogram. `bucket_option` and `bucket_counts` must be both set, or both unset. Buckets are numbered in the range of [0, N], with a total of N+1 buckets. There must be at least two buckets (a single-bucket histogram gives no information that isn't already provided by `count`). The first bucket is the underflow bucket which has a lower bound of -inf. The last bucket is the overflow bucket which has an upper bound of +inf. All other buckets (if any) are called "finite" buckets because they have finite lower and upper bounds. As described below, there are three ways to define the finite buckets. (1) Buckets with constant width. (2) Buckets with exponentially growing widths. (3) Buckets with arbitrary user-provided widths. In all cases, the buckets cover the entire real number line (-inf, +inf). Bucket upper bounds are exclusive and lower bounds are inclusive. The upper bound of the underflow bucket is equal to the lower bound of the smallest finite bucket; the lower bound of the overflow bucket is equal to the upper bound of the largest finite bucket. `bucket_option` can be only one of the following:
`linear_buckets`	`LinearBuckets` Buckets with constant width.
`exponential_buckets`	`ExponentialBuckets` Buckets with exponentially growing width.
`explicit_buckets`	`ExplicitBuckets` Buckets with arbitrary user-provided width.

Fields

Fields
`bounds[]`	`double` 'bound' is a list of strictly increasing boundaries between buckets. Note that a list of length N-1 defines N buckets because of fenceposting.

TraceSpan

A span represents a single operation within a trace. Spans can be nested to form a trace tree. Often, a trace contains a root span that describes the end-to-end latency, and one or more subspans for its sub-operations. A trace can also contain multiple root spans, or none at all. Spans do not need to be contiguous—there may be gaps or overlaps between spans in a trace.

Fields
`name`	`string` The resource name of the span in the following format: `projects/[PROJECT_ID]/traces/[TRACE_ID]/spans/[SPAN_ID]` [TRACE_ID] is a unique identifier for a trace within a project; it is a 32-character hexadecimal encoding of a 16-byte array.

`display_name`	`TruncatableString` A description of the span's operation (up to 128 bytes). Stackdriver Trace displays the description in the Google Cloud Platform Console. For example, the display name can be a qualified method name or a file name and a line number where the operation is called. A best practice is to use the same display name within an application and at the same call point. This makes it easier to correlate spans in different traces.
`start_time`	`Timestamp` The start time of the span. On the client side, this is the time kept by the local machine where the span execution starts. On the server side, this is the time when the server's application handler starts running.
`end_time`	`Timestamp` The end time of the span. On the client side, this is the time kept by the local machine where the span execution ends. On the server side, this is the time when the server application handler stops running.
`attributes`	`Attributes` A set of attributes on the span. You can have up to 32 attributes per span.
`status`	`Status` An optional final status for this span.
`same_process_as_parent_span`	`BoolValue` (Optional) Set this parameter to indicate whether this span is in the same process as its parent. If you do not set this parameter, Stackdriver Trace is unable to take advantage of this helpful information.
`child_span_count`	`Int32Value` An optional number of child spans that were generated while this span was active. If set, allows implementation to detect missing child spans.
`span_kind`	`SpanKind` Distinguishes between spans generated in a particular context. For example, two spans with the same name may be distinguished using `CLIENT` (caller) and `SERVER` (callee) to identify an RPC call.

AttributeValue

The allowed types for [VALUE] in a [KEY]:[VALUE] attribute.

Fields
Union field `value`. The type of the value. `value` can be only one of the following:

The value can be a string up to 256 bytes, a signed 64-bit integer, or the Boolean values `true` and `false`. For example: `"/instance_id": "my-instance" "/http/user_agent": "" "/http/request_bytes": 300 "example.com/myattribute": true`
`dropped_attributes_count`	`int32` The number of attributes that were discarded. Attributes can be discarded because their keys are too long or because there are too many attributes. If this value is 0 then all attributes are valid.

attribute_map

map<string, AttributeValue>

"example.com/myattribute": true

dropped_attributes_count

int32

The number of attributes that were discarded. Attributes can be discarded because their keys are too long or because there are too many attributes. If this value is 0 then all attributes are valid.

SpanKind

Type of span. Can be used to specify additional relationships between spans in addition to a parent/child relationship.

Enums
`SPAN_KIND_UNSPECIFIED`	Unspecified. Do NOT use as default. Implementations MAY assume SpanKind.INTERNAL to be default.
`INTERNAL`	Indicates that the span is used internally. Default value.
`SERVER`	Indicates that the span covers server-side handling of an RPC or other remote network request.
`CLIENT`	Indicates that the span covers the client-side wrapper around an RPC or other remote request.

`CONSUMER`	Indicates that the span describes consumer receiving a message from a broker. Unlike client and server, there is no direct critical path latency relationship between producer and consumer spans (e.g. receiving a message from a pubsub service subscription).

TruncatableString

Represents a string that might be shortened to a specified length.

Fields

Fields
`value`	`string` The shortened string. For example, if the original string is 500 bytes long and the limit of the string is 128 bytes, then `value` contains the first 128 bytes of the 500-byte string. Truncation always happens on a UTF8 character boundary. If there are multi-byte characters in the string, then the length of the shortened string might be less than the size limit.
`truncated_byte_count`	`int32` The number of bytes removed from the original string. If this value is 0, then the string was not shortened.
