type ContainerTagsBuffer ¶
type ContainerTagsBuffer interface {
Start()
Stop()
IsEnabled() bool
AsyncEnrichment(containerID string, applyResult func([]string, error, *DebugInfo), payloadSize int64) (pending bool)
}
ContainerTagsBuffer is a buffer for container tag resolution.
In kubernetes, containers start and emit spans before container tags (pod, deployment..) are extracted from the kubelet. This buffer holds incoming tagging requests until specific tags (e.g., "kube_pod_name")
Safety mechanisms - at most 10% of the max trace-agent memory can be used by payloads pending resolution - payloads can't be buffered more then `maxBufferDuration` - if we failed the resolution of a containerID before the time limit, further payloads from this containerID are not buffered
func NewContainerTagsBuffer ¶
func NewContainerTagsBuffer(conf *config.AgentConfig, statsd statsd.ClientInterface) ContainerTagsBuffer
NewContainerTagsBuffer creates a new buffer if it's enabled in configuration and the agent is in kubernetes elses returns a NoOpTagBuffer
type DebugInfo ¶ added in v0.80.0
type DebugInfo struct {
Error string
LatencyMs int64
WasBuffered bool
BufferMs int64
BufferEvictionReason string
}
DebugInfo contains troubleshooting information about container tags resolution. It is only populated when a notable event occurs (error, buffering, denial).
type NoOpTagsBuffer ¶
type NoOpTagsBuffer struct{}
NoOpTagsBuffer is a tagsbuffer that does nothing
func (*NoOpTagsBuffer) AsyncEnrichment ¶
AsyncEnrichment returns false as no enrichment is pending
func (*NoOpTagsBuffer) IsEnabled ¶
func (n *NoOpTagsBuffer) IsEnabled() bool
IsEnabled returns false
