Rafael Franco 7c46c150bd
Clarify documentation around what constructors do (#1125)
The wording of the documentation is slightly misleading. Before this
commit, it says that the returned collectors are "already registered".
This could be interpreted in two ways, one could think that promauto
keeps some sort of cache of already registered Collectors that are
returned by this package, and the other way is that the Collectors
constructed are registered before being returned. What is actually
happening is the latter, and the wording after this PR leaves no room to
think that the former could be the case.

Extend prometheus.Registry to implement Collector (#1103)
* prometheus: implement Collector interface for Registry

This change allows Registries to be used as Collectors.

This enables new instances of Registry to be passed to ephemeral
subroutines for collecting metrics from subroutines which are still
running:

```go
package main

import (
  "fmt"

  "github.com/prometheus/client_golang/prometheus"
)

func main() {
  globalReg := prometheus.NewRegistry()

  for i := 0; i < 100; i++ {
    workerReg := prometheus.WrapRegistererWith(prometheus.Labels{
      // Add an ID label so registered metrics from workers don't
      // collide.
      "worker_id": fmt.Sprintf("%d", i),
    }, prometheus.NewRegistry()

    globalReg.MustRegister(workerReg)

    go func(i int) {
      runWorker(workerReg)

      // Unregister any metrics the worker may have created.
      globalReg.Unregister(workerReg)
    }(i)
  }
}

// runWorker runs a worker, registering worker-specific metrics.
func runWorker(reg *prometheus.Registry) {
  // ... register metrics ...
  // ... do work ...
}
```

This change makes it easier to avoid leaking metrics from subroutines
which do not consistently properly unregister metrics.

* Make the Go 1.17 collector thread-safe (#969)

* Use simpler locking in the Go 1.17 collector (#975)

A previous PR made it so that the Go 1.17 collector locked only around
uses of rmSampleBuf, but really that means that Metric values may be
sent over the channel containing some values from future metrics.Read
calls. While generally-speaking this isn't a problem, we lose any
consistency guarantees provided by the runtime/metrics package.

Also, that optimization to not just lock around all of Collect was
premature. Truthfully, Collect is called relatively infrequently, and
its critical path is fairly fast (10s of µs). To prove it, this change
also adds a benchmark.

name            old time/op  new time/op  delta
GoCollector-16  43.7µs ± 2%  43.2µs ± 2%   ~     (p=0.190 n=9+9)

Note that because the benchmark is single-threaded it actually looks
like it might be getting *slightly* faster, because all those Collect
calls for the Metrics are direct calls instead of interface calls.

* API client: make http reads more efficient (#976)

Replace `io.ReadAll` with `bytes.Buffer.ReadFrom`.
Both need to resize a buffer until they have finished reading;
the former increases by 1.25x each time while the latter uses 2x.

Also added a benchmark to demonstrate the benefit:

* Reduce granularity of histogram buckets for Go 1.17 collector (#974)

The Go runtime/metrics package currently exports extremely granular
histograms. Exponentially bucket any histogram with unit "seconds"
or "bytes" instead to dramatically reduce the number of buckets, and
thus the number of metrics.

This change also adds a test to check for expected cardinality to
prevent cardinality surprises in the future.

Michael Knyszek 9b785b0349 Reduce granularity of histogram buckets for Go 1.17 collector (#974)
The Go runtime/metrics package currently exports extremely granular
histograms. Exponentially bucket any histogram with unit "seconds"
or "bytes" instead to dramatically reduce the number of buckets, and
thus the number of metrics.

This change also adds a test to check for expected cardinality to
prevent cardinality surprises in the future.
