Functions

func AgentURLFromEnv

func AgentURLFromEnv() *url.URL

AgentURLFromEnv determines the trace agent URL from environment variable DD_TRACE_AGENT_URL. If the determined value is valid and the scheme is supported (unix, http or https), it will return an *url.URL. Otherwise, it returns nil.

func BoolEnv

func BoolEnv(key string, def bool) bool

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

func CleanGitMetadataTags

func CleanGitMetadataTags(tags map[string]string)

CleanGitMetadataTags cleans up tags from git metadata

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 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 GetGitMetadataTags

func GetGitMetadataTags() map[string]string

GetGitMetadataTags returns git metadata tags

func GetTracerGitMetadataTags

func GetTracerGitMetadataTags() map[string]string

GetTracerGitMetadataTags returns git metadata tags for tracer NB: Currently tracer inject tags with some workaround (only with _dd prefix and only for the first span in payload) So we provide different tag names

func IntEnv

func IntEnv(key string, def int) int

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

func ParseTagString

func ParseTagString(str string) map[string]string

ParseTagString returns tags parsed from string as map

func ResetGitMetadataTags

func ResetGitMetadataTags()

ResetGitMetadataTags reset cashed metadata tags
