@ -17,6 +17,7 @@ The following tip changes can be tested by building VictoriaMetrics components f
* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): add `exported_` prefix to metric names exported by scrape targets if these metric names clash with [automatically generated metrics](https://docs.victoriametrics.com/vmagent.html#automatically-generated-metrics) such as `up`, `scrape_samples_scraped`, etc. This prevents from corruption of automatically generated metrics. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3406).
* FEATURE: [VictoriaMetrics cluster](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html): improve error message when the requested path cannot be properly parsed, so users could identify the issue and properly fix the path. Now the error message links to [url format docs](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#url-format). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3402).
* FEATURE: [vmctl](https://docs.victoriametrics.com/vmctl.html): add ability to copy data from sources via Prometheus `remote_read` protocol. See [these docs](https://docs.victoriametrics.com/vmctl.html#migrating-data-by-remote-read-protocol). The related issues: [one](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3132) and [two](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1101).

// if (any.is(Foo.class)) {
// foo = any.unpack(Foo.class);
// }
//
// Example 3: Pack and unpack a message in Python.
//
// foo = Foo(...)
// any = Any()
// any.Pack(foo)
// ...
// if any.Is(Foo.DESCRIPTOR):
// any.Unpack(foo)
// ...
//
// Example 4: Pack and unpack a message in Go
//
// foo := &pb.Foo{...}
// any, err := ptypes.MarshalAny(foo)
// ...
// foo := &pb.Foo{}
// if err := ptypes.UnmarshalAny(any, foo); err != nil {
// ...
// }
//
// The pack methods provided by protobuf library will by default use
// 'type.googleapis.com/full.type.name' as the type URL and the unpack
// methods only use the fully qualified type name after the last '/'
// in the type URL, for example "foo.bar.com/x/y.z" will yield type
// name "y.z".
//
//
// JSON
// ====
// The JSON representation of an `Any` value uses the regular
// representation of the deserialized, embedded message, with an
// additional field `@type` which contains the type URL. Example:
//
// package google.profile;
// message Person {
// string first_name = 1;
// string last_name = 2;
// }
//
// {
// "@type": "type.googleapis.com/google.profile.Person",
// "firstName": <string>,
// "lastName": <string>
// }
//
// If the embedded message type is well-known and has a custom JSON
// representation, that representation will be embedded adding a field
// `value` which holds the custom JSON in addition to the `@type`
// field. Example (for message [google.protobuf.Duration][]):
//
// {
// "@type": "type.googleapis.com/google.protobuf.Duration",
// "value": "1.212s"
// }
//
type Any struct {
// A URL/resource name that uniquely identifies the type of the serialized
// protocol buffer message. This string must contain at least
// one "/" character. The last segment of the URL's path must represent
// the fully qualified name of the type (as in
// `path/google.protobuf.Duration`). The name should be in a canonical form
// (e.g., leading "." is not accepted).
//
// In practice, teams usually precompile into the binary all types that they
// expect it to use in the context of Any. However, for URLs which use the
// scheme `http`, `https`, or no scheme, one can optionally set up a type
// server that maps type URLs to message definitions as follows:
//
// * If no scheme is provided, `https` is assumed.
// * An HTTP GET on the URL must yield a [google.protobuf.Type][]
// value in binary format, or produce an error.
// * Applications are allowed to cache lookup results based on the
// URL, or have them precompiled into a binary to avoid any
// lookup. Therefore, binary compatibility needs to be preserved
// on changes to types. (Use versioned type names to manage
// breaking changes.)
//
// Note: this functionality is not currently available in the official
// protobuf release, and it is not used for type URLs beginning with
// type.googleapis.com.
//
// Schemes other than `http`, `https` (or the empty scheme) might be
// used with implementation specific semantics.
//
TypeUrl string `protobuf:"bytes,1,opt,name=type_url,json=typeUrl,proto3" json:"type_url,omitempty"`
// Must be a valid serialized protocol buffer of the above specified type.
Value []byte `protobuf:"bytes,2,opt,name=value,proto3" json:"value,omitempty"`

// A Duration represents a signed, fixed-length span of time represented
// as a count of seconds and fractions of seconds at nanosecond
// resolution. It is independent of any calendar and concepts like "day"
// or "month". It is related to Timestamp in that the difference between
// two Timestamp values is a Duration and it can be added or subtracted
// from a Timestamp. Range is approximately +-10,000 years.
//
// # Examples
//
// Example 1: Compute Duration from two Timestamps in pseudo code.
//
// Timestamp start = ...;
// Timestamp end = ...;
// Duration duration = ...;
//
// duration.seconds = end.seconds - start.seconds;
// duration.nanos = end.nanos - start.nanos;
//
// if (duration.seconds < 0 && duration.nanos > 0) {
// duration.seconds += 1;
// duration.nanos -= 1000000000;
// } else if (durations.seconds > 0 && duration.nanos < 0) {
// duration.seconds -= 1;
// duration.nanos += 1000000000;
// }
//
// Example 2: Compute Timestamp from Timestamp + Duration in pseudo code.
//
// Timestamp start = ...;
// Duration duration = ...;
// Timestamp end = ...;
//
// end.seconds = start.seconds + duration.seconds;
// end.nanos = start.nanos + duration.nanos;
//
// if (end.nanos < 0) {
// end.seconds -= 1;
// end.nanos += 1000000000;
// } else if (end.nanos >= 1000000000) {
// end.seconds += 1;
// end.nanos -= 1000000000;
// }
//
// Example 3: Compute Duration from datetime.timedelta in Python.
//
// td = datetime.timedelta(days=3, minutes=10)
// duration = Duration()
// duration.FromTimedelta(td)
//
// # JSON Mapping
//
// In JSON format, the Duration type is encoded as a string rather than an
// object, where the string ends in the suffix "s" (indicating seconds) and
// is preceded by the number of seconds, with nanoseconds expressed as
// fractional seconds. For example, 3 seconds with 0 nanoseconds should be
// encoded in JSON format as "3s", while 3 seconds and 1 nanosecond should
// be expressed in JSON format as "3.000000001s", and 3 seconds and 1
// microsecond should be expressed in JSON format as "3.000001s".
//
//
type Duration struct {
// Signed seconds of the span of time. Must be from -315,576,000,000
// to +315,576,000,000 inclusive. Note: these bounds are computed from:
// 60 sec/min * 60 min/hr * 24 hr/day * 365.25 days/year * 10000 years
Seconds int64 `protobuf:"varint,1,opt,name=seconds,proto3" json:"seconds,omitempty"`

// of time. Durations less than one second are represented with a 0
// `seconds` field and a positive or negative `nanos` field. For durations
// of one second or more, a non-zero value for the `nanos` field must be

// `FieldMask` represents a set of symbolic field paths, for example:
//
// paths: "f.a"
// paths: "f.b.d"
//
// Here `f` represents a field in some root message, `a` and `b`
// fields in the message found in `f`, and `d` a field found in the
// message in `f.b`.
//
// Field masks are used to specify a subset of fields that should be
// returned by a get operation or modified by an update operation.
// Field masks also have a custom JSON encoding (see below).
//
// # Field Masks in Projections
//
// When used in the context of a projection, a response message or
// sub-message is filtered by the API to only contain those fields as
// specified in the mask. For example, if the mask in the previous
// example is applied to a response message as follows:
//
// f {
// a : 22
// b {
// d : 1
// x : 2
// }
// y : 13
// }
// z: 8
//
// The result will not contain specific values for fields x,y and z
// (their value will be set to the default, and omitted in proto text
// output):
//
//
// f {
// a : 22
// b {
// d : 1
// }
// }
//
// A repeated field is not allowed except at the last position of a
// paths string.
//
// If a FieldMask object is not present in a get operation, the
// operation applies to all fields (as if a FieldMask of all fields
// had been specified).
//
// Note that a field mask does not necessarily apply to the
// top-level response message. In case of a REST get operation, the
// field mask applies directly to the response, but in case of a REST
// list operation, the mask instead applies to each individual message
// in the returned resource list. In case of a REST custom method,
// other definitions may be used. Where the mask applies will be
// clearly documented together with its declaration in the API. In
// any case, the effect on the returned resource/resources is required
// behavior for APIs.
//
// # Field Masks in Update Operations
//
// A field mask in update operations specifies which fields of the
// targeted resource are going to be updated. The API is required
// to only change the values of the fields as specified in the mask
// and leave the others untouched. If a resource is passed in to
// describe the updated values, the API ignores the values of all
// fields not covered by the mask.
//
// If a repeated field is specified for an update operation, new values will
// be appended to the existing repeated field in the target resource. Note that
// a repeated field is only allowed in the last position of a `paths` string.
//
// If a sub-message is specified in the last position of the field mask for an
// update operation, then new value will be merged into the existing sub-message
// in the target resource.
//
// For example, given the target message:
//
// f {
// b {
// d: 1
// x: 2
// }
// c: [1]
// }
//
// And an update message:
//
// f {
// b {
// d: 10
// }
// c: [2]
// }
//
// then if the field mask is:
//
// paths: ["f.b", "f.c"]
//
// then the result will be:
//
// f {
// b {
// d: 10
// x: 2
// }
// c: [1, 2]
// }
//
// An implementation may provide options to override this default behavior for
// repeated and message fields.
//
// In order to reset a field's value to the default, the field must
// be in the mask and set to the default value in the provided resource.
// Hence, in order to reset all fields of a resource, provide a default
// instance of the resource and set all fields in the mask, or do
// not provide a mask as described below.
//
// If a field mask is not present on update, the operation applies to
// all fields (as if a field mask of all fields has been specified).
// Note that in the presence of schema evolution, this may mean that
// fields the client does not know and has therefore not filled into
// the request will be reset to their default. If this is unwanted
// behavior, a specific service may require a client to always specify
// a field mask, producing an error if not.
//
// As with get operations, the location of the resource which
// describes the updated values in the request message depends on the
// operation kind. In any case, the effect of the field mask is
// required to be honored by the API.
//
// ## Considerations for HTTP REST
//
// The HTTP kind of an update operation which uses a field mask must
// be set to PATCH instead of PUT in order to satisfy HTTP semantics
// (PUT must only be used for full updates).
//
// # JSON Encoding of Field Masks
//
// In JSON, a field mask is encoded as a single string where paths are
// separated by a comma. Fields name in each path are converted
// to/from lower-camel naming conventions.
//
// As an example, consider the following message declarations:
//
// message Profile {
// User user = 1;
// Photo photo = 2;
// }
// message User {
// string display_name = 1;
// string address = 2;
// }
//
// In proto a field mask for `Profile` may look as such:
//
// mask {
// paths: "user.display_name"
// paths: "photo"
// }
//
// In JSON, the same mask is represented as below:
//
// {
// mask: "user.displayName,photo"
// }
//
// # Field Masks and Oneof Fields
//
// Field masks treat fields in oneofs just as regular fields. Consider the
// following message:
//
// message SampleMessage {
// oneof test_oneof {
// string name = 4;
// SubMessage sub_message = 9;
// }
// }
//
// The field mask can be:
//
// mask {
// paths: "name"
// }
//
// Or:
//
// mask {
// paths: "sub_message"
// }
//
// Note that oneof type names ("test_oneof" in this case) cannot be used in
// paths.
//
// ## Field Mask Verification
//
// The implementation of any API method which has a FieldMask type field in the
// request should verify the included field paths, and return an
// `INVALID_ARGUMENT` error if any path is duplicated or unmappable.

// A Timestamp represents a point in time independent of any time zone or local

// nanosecond resolution. The count is relative to an epoch at UTC midnight on
// January 1, 1970, in the proleptic Gregorian calendar which extends the
// Gregorian calendar backwards to year one.
//
// All minutes are 60 seconds long. Leap seconds are "smeared" so that no leap
// second table is needed for interpretation, using a [24-hour linear
// smear](https://developers.google.com/time/smear).
//
// The range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By
// restricting to that range, we ensure that we can convert to and from [RFC
// 3339](https://www.ietf.org/rfc/rfc3339.txt) date strings.
//
// # Examples
//
// Example 1: Compute Timestamp from POSIX `time()`.
//
// Timestamp timestamp;
// timestamp.set_seconds(time(NULL));
// timestamp.set_nanos(0);
//
// Example 2: Compute Timestamp from POSIX `gettimeofday()`.
//
// struct timeval tv;
// gettimeofday(&tv, NULL);
//
// Timestamp timestamp;
// timestamp.set_seconds(tv.tv_sec);
// timestamp.set_nanos(tv.tv_usec * 1000);
//
// Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.
//
// FILETIME ft;
// GetSystemTimeAsFileTime(&ft);
// UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;
//
// // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
// // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
// Timestamp timestamp;
// timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
// timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));
//
// Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.
//
// long millis = System.currentTimeMillis();
//
// Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
// .setNanos((int) ((millis % 1000) * 1000000)).build();
//
//
// Example 5: Compute Timestamp from current time in Python.
//
// timestamp = Timestamp()
// timestamp.GetCurrentTime()
//
// # JSON Mapping
//
// In JSON format, the Timestamp type is encoded as a string in the
// [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
// format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
// where {year} is always expressed using four digits while {month}, {day},
// {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
// is required. A proto3 JSON serializer should always use UTC (as indicated by
// "Z") when printing the Timestamp type and a proto3 JSON parser should be
// able to accept both UTC and other timezones (as indicated by an offset).
//
// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
// 01:30 UTC on January 15, 2017.
//
// In JavaScript, one can convert a Date object to this format using the
// standard
// [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
// method. In Python, a standard `datetime.datetime` object can be converted
// to this format using
// [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with
// the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use
// the Joda Time's [`ISODateTimeFormat.dateTime()`](
// http://www.joda.org/joda-time/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime%2D%2D
// ) to obtain a formatter capable of generating timestamps in this format.

// different in the exposition format vs. in a TSDB chunk vs. for the in-memory
// representation as Go types. In the TSDB, as an additional aspects, the span
// layout is only stored once per chunk, while many histograms with that same
// chunk layout are then only stored with their buckets (so that even a single
// empty bucket will be stored many times).
//
// For the Go types, an additional Span takes 8 bytes. Similarly, an additional
// bucket takes 8 bytes. Therefore, with a single separating empty bucket, both
// options have the same storage requirement, but the single-span solution is
// easier to iterate through. Still, the safest bet is to use maxEmptyBuckets==0

// Here a bit of context about the behavior for the last bucket counting
// regular numbers (called simply "last bucket" below) and the bucket
// counting observations of ±Inf (called "inf bucket" below, with an idx
// one higher than that of the "last bucket"):
//
// If we apply the usual formula to the last bucket, its upper bound
// would be calculated as +Inf. The reason is that the max possible
// regular float64 number (math.MaxFloat64) doesn't coincide with one of
// the calculated bucket boundaries. So the calculated boundary has to
// be larger than math.MaxFloat64, and the only float64 larger than
// math.MaxFloat64 is +Inf. However, we want to count actual
// observations of ±Inf in the inf bucket. Therefore, we have to treat
// the upper bound of the last bucket specially and set it to
// math.MaxFloat64. (The upper bound of the inf bucket, with its idx
// being one higher than that of the last bucket, naturally comes out as
// +Inf by the usual formula. So that's fine.)
//
// math.MaxFloat64 has a frac of 0.9999999999999999 and an exp of
// 1024. If there were a float64 number following math.MaxFloat64, it
// would have a frac of 1.0 and an exp of 1024, or equivalently a frac
// of 0.5 and an exp of 1025. However, since frac must be smaller than
// 1, and exp must be smaller than 1025, either representation overflows
// a float64. (Which, in turn, is the reason that math.MaxFloat64 is the
// largest possible float64. Q.E.D.) However, the formula for
// calculating the upper bound from the idx and schema of the last
// bucket results in precisely that. It is either frac=1.0 & exp=1024
// (for schema < 0) or frac=0.5 & exp=1025 (for schema >=0). (This is,
// by the way, a power of two where the exponent itself is a power of

// [*] unchanged in terms of which bucket indices they represent. but to achieve

//
// \/ this one is "unchanged"
// spans : [ 0 , 3 ] [1,1] [ 1 , 4 ] [ 3 , 3 ]
// bucket idx : [0] [1] [2] 3 [4] 5 [6] [7] [8] [9] 10 11 12 [13] [14] [15]
// raw values 6 3 0 3 0 0 2 4 5 0 1
// deltas 6 -3 -3 3 -3 0 2 2 1 -5 1
// delta mods: / \ / \ / \
//
// Note that whenever any new buckets are introduced, the subsequent "old"
// bucket needs to readjust its delta to the new base of 0. Thus, for the caller

## [Unreleased]
## [1.11.1/0.33.0] 2022-10-19
### Added
- The Prometheus exporter in `go.opentelemetry.io/otel/exporters/prometheus` registers with a Prometheus registerer on creation.
By default, it will register with the default Prometheus registerer.
A non-default registerer can be used by passing the `WithRegisterer` option. (#3239)
- Added the `WithAggregationSelector` option to the `go.opentelemetry.io/otel/exporters/prometheus` package to change the default `AggregationSelector` used. (#3341)
- The Prometheus exporter in `go.opentelemetry.io/otel/exporters/prometheus` converts the `Resource` associated with metric exports into a `target_info` metric. (#3285)
### Changed
- The `"go.opentelemetry.io/otel/exporters/prometheus".New` function is updated to return an error.
It will return an error if the exporter fails to register with Prometheus. (#3239)
### Fixed
- The URL-encoded values from the `OTEL_RESOURCE_ATTRIBUTES` environment variable are decoded. (#2963)
- The `baggage.NewMember` function decodes the `value` parameter instead of directly using it.
This fixes the implementation to be compliant with the W3C specification. (#3226)
- Slice attributes of the `attribute` package are now comparable based on their value, not instance. (#3108 #3252)
- The `Shutdown` and `ForceFlush` methods of the `"go.opentelemetry.io/otel/sdk/trace".TraceProvider` no longer return an error when no processor is registered. (#3268)
- The Prometheus exporter in `go.opentelemetry.io/otel/exporters/prometheus` cumulatively sums histogram buckets. (#3281)
- The sum of each histogram data point is now uniquely exported by the `go.opentelemetry.io/otel/exporters/otlpmetric` exporters. (#3284, #3293)
- Recorded values for asynchronous counters (`Counter` and `UpDownCounter`) are interpreted as exact, not incremental, sum values by the metric SDK. (#3350, #3278)
- `UpDownCounters` are now correctly output as Prometheus gauges in the `go.opentelemetry.io/otel/exporters/prometheus` exporter. (#3358)
- The Prometheus exporter in `go.opentelemetry.io/otel/exporters/prometheus` no longer describes the metrics it will send to Prometheus on startup.
Instead the exporter is defined as an "unchecked" collector for Prometheus.
This fixes the `reader is not registered` warning currently emitted on startup. (#3291 #3342)
- The `go.opentelemetry.io/otel/exporters/prometheus` exporter now correctly adds `_total` suffixes to counter metrics. (#3360)
- The `go.opentelemetry.io/otel/exporters/prometheus` exporter now adds a unit suffix to metric names.
This can be disabled using the `WithoutUnits()` option added to that package. (#3352)

- Flush pending measurements with the `PeriodicReader` in the `go.opentelemetry.io/otel/sdk/metric` when `ForceFlush` or `Shutdown` are called. (#3220)
- Update histogram default bounds to match the requirements of the latest specification. (#3222)
