Functions

func BoolEnv

func BoolEnv(key string, def bool) bool

BoolEnv returns the parsed boolean value of an environment variable, or def otherwise.

func ContainerID

func ContainerID() string

ContainerID attempts to return the container ID from /proc/self/cgroup or empty on failure.

func DurationEnv

func DurationEnv(key string, def time.Duration) time.Duration

DurationEnv returns the parsed duration value of an environment variable, or def otherwise.

func EntityID

func EntityID() string

EntityID attempts to return the container ID or the cgroup node controller's inode if the container ID is not available. The cid is prefixed with `cid-` and the inode with `in-`.

func FloatEnv

func FloatEnv(key string, def float64) float64

FloatEnv returns the parsed float64 value of an environment variable, or def otherwise.

func ForEachStringTag

func ForEachStringTag(str string, fn func(key string, val string))

ForEachStringTag runs fn on every key:val pair encountered in str. str may contain multiple key:val pairs separated by either space or comma (but not a mixture of both).

func IntEnv

func IntEnv(key string, def int) int

IntEnv returns the parsed int value of an environment variable, or def otherwise.

func IsExecutionTraced

func IsExecutionTraced(ctx context.Context) bool

IsExecutionTraced returns whether ctx is associated with an execution trace task, as indicated via WithExecutionTraced

func ParseTagString

func ParseTagString(str string) map[string]string

ParseTagString returns tags parsed from string as map

func WithExecutionNotTraced

func WithExecutionNotTraced(ctx context.Context) context.Context

WithExecutionNotTraced marks that the context is *not* covered by an execution trace task. This is intended to prevent child spans (which inherit information from ctx) from being considered covered by a task, when an integration may create its own child span with its own execution trace task.

func WithExecutionTraced

func WithExecutionTraced(ctx context.Context) context.Context

WithExecutionTraced marks ctx as being associated with an execution trace task. It is assumed that ctx already contains a trace task. The caller is responsible for ending the task.

This is intended for a specific case where the database/sql contrib package only creates spans *after* an operation, in case the operation was unavailable, and thus execution trace tasks tied to the span only capture the very end. This function enables creating a task *before* creating a span, and communicating to the APM tracer that it does not need to create a task. In general, APM instrumentation should prefer creating tasks around the operation rather than after the fact, if possible.

Types

type LockMap

type LockMap struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

LockMap uses an RWMutex to synchronize map access to allow for concurrent access. This should not be used for cases with heavy write load and performance concerns.

func NewLockMap

func NewLockMap(m map[string]string) *LockMap

func (*LockMap) Clear

func (l *LockMap) Clear()

func (*LockMap) Get

func (l *LockMap) Get(k string) string

func (*LockMap) Iter

func (l *LockMap) Iter(f func(key string, val string))

Iter iterates over all the map entries passing in keys and values to provided func f. Note this is READ ONLY.

func (*LockMap) Len

func (l *LockMap) Len() int

func (*LockMap) Set

func (l *LockMap) Set(k, v string)
