So why are these constructors locked away in a +// separate package? +// +// The main problem is that registration may fail, e.g. if a metric inconsistent +// with or equal to the newly to be registered one is already registered. +// Therefore, the Register method in the prometheus.Registerer interface returns +// an error, and the same is the case for the top-level prometheus.Register +// function that registers with the global registry. The prometheus package also +// provides MustRegister versions for both. They panic if the registration +// fails, and they clearly call this out by using the Must… idiom. Panicking is +// problematic in this case because it doesn't just happen on input provided by +// the caller that is invalid on its own. Things are a bit more subtle here: +// Metric creation and registration tend to be spread widely over the +// codebase. It can easily happen that an incompatible metric is added to an +// unrelated part of the code, and suddenly code that used to work perfectly +// fine starts to panic (provided that the registration of the newly added +// metric happens before the registration of the previously existing +// metric). This may come as an even bigger surprise with the global registry, +// where simply importing another package can trigger a panic (if the newly +// imported package registers metrics in its init function). At least, in the +// prometheus package, creation of metrics and other collectors is separate from +// registration. You first create the metric, and then you decide explicitly if +// you want to register it with a local or the global registry, and if you want +// to handle the error or risk a panic. With the constructors in the promauto +// package, registration is automatic, and if it fails, it will always +// panic. Furthermore, the constructors will often be called in the var section +// of a file, which means that panicking will happen as a side effect of merely +// importing a package. +// +// A separate package allows conservative users to entirely ignore it. And +// whoever wants to use it, will do so explicitly, with an opportunity to read +// this warning. +// +// Enjoy promauto responsibly! +package promauto + +import "github.com/prometheus/client_golang/prometheus" + +// NewCounter works like the function of the same name in the prometheus package +// but it automatically registers the Counter with the +// prometheus.DefaultRegisterer.

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. +// +// +type Timestamp struct { + state protoimpl.MessageState + sizeCache protoimpl.SizeCache + unknownFields protoimpl.UnknownFields + + // Represents seconds of UTC time since Unix epoch + // 1970-01-01T00:00:00Z.
