UserAgent is the user agent to be added to the outgoing requests from the exporters.

var UserAgent = fmt.Sprintf("opencensus-go/%s", opencensus.Version())

func MonotonicEndTime(start time.Time) time.Time

MonotonicEndTime returns the end time at present but offset from start, monotonically.

The monotonic clock is used in subtractions hence the duration since start added back to start gives end as a monotonic time. See https://golang.org/pkg/time/#hdr-Monotonic_Clocks

func Sanitize(s string) string

Sanitize returns a string that is trunacated to 100 characters if it's too long, and replaces non-alphanumeric characters to underscores.

BucketConfiguration stores the number of samples to store for span buckets for successful and failed spans for a particular span name.

type BucketConfiguration struct {
    Name                 string
    MaxRequestsSucceeded int
    MaxRequestsErrors    int
}

ErrorBucketSummary is a summary of an error bucket.

type ErrorBucketSummary struct {
    ErrorCode int32
    Size      int
}

LatencyBucketSummary is a summary of a latency bucket.

type LatencyBucketSummary struct {
    MinLatency, MaxLatency time.Duration
    Size                   int
}

PerMethodSummary is a summary of the spans stored for a single span name.

type PerMethodSummary struct {
    Active         int
    LatencyBuckets []LatencyBucketSummary
    ErrorBuckets   []ErrorBucketSummary
}
