Functions ¶
func CleanInfoExtraLines ¶
CleanInfoExtraLines removes empty lines from template code indentation. The idea is that an indented empty line (only indentation spaces) is because of code indentation, so we remove it. Real legit empty lines contain no space.
func Info ¶
func Info(w io.Writer, conf *config.AgentConfig) error
Info writes a standard info message describing the running agent. This is not the current program, but an already running program, which we query with an HTTP request.
If error is nil, means the program is running. If not, it displays a pretty-printed message anyway (for support)
func InitInfo ¶
func InitInfo(conf *config.AgentConfig) error
InitInfo initializes the info structure. It should be called only once.
func Languages ¶
func Languages() []string
Languages exposes languages reporting traces to the Agent.
func UpdateRateByService ¶
UpdateRateByService updates the RateByService map and the filtered RateByServiceFiltered map.
func UpdateReceiverStats ¶
func UpdateReceiverStats(rs *ReceiverStats)
UpdateReceiverStats updates internal stats about the receiver.
func UpdateStatsWriterInfo ¶
func UpdateStatsWriterInfo(sws StatsWriterInfo)
UpdateStatsWriterInfo updates internal stats writer stats
func UpdateTraceWriterInfo ¶
func UpdateTraceWriterInfo(tws TraceWriterInfo)
UpdateTraceWriterInfo updates internal trace writer stats
func UpdateWatchdogInfo ¶
UpdateWatchdogInfo updates internal stats about the watchdog.
Types ¶
type EndpointStats ¶
type EndpointStats struct { // TracesPayload is the number of traces payload sent, including errors. // If several URLs are given, each URL counts for one. TracesPayload int64 // TracesPayloadError is the number of traces payload sent with an error. // If several URLs are given, each URL counts for one. TracesPayloadError int64 // TracesBytes is the size of the traces payload data sent, including errors. // If several URLs are given, it does not change the size (shared for all). // This is the raw data, encoded, compressed. TracesBytes int64 // TracesStats is the number of stats in the traces payload data sent, including errors. // If several URLs are given, it does not change the size (shared for all). TracesStats int64 }
EndpointStats contains stats about the volume of data written
type ReceiverStats ¶
ReceiverStats is used to store all the stats per tags.
func NewReceiverStats ¶
func NewReceiverStats() *ReceiverStats

func (*ReceiverStats) Acc ¶
func (rs *ReceiverStats) Acc(recent *ReceiverStats)
Acc accumulates the stats from another ReceiverStats struct.

func (*ReceiverStats) LogAndResetStats ¶ added in v0.41.0
func (rs *ReceiverStats) LogAndResetStats()
LogAndResetStats logs one-line summaries of ReceiverStats and resets internal data. Problematic stats are logged as warnings.
func (*ReceiverStats) PublishAndReset ¶ added in v0.41.0
func (rs *ReceiverStats) PublishAndReset()
PublishAndReset updates stats about per-tag stats
type SpansMalformed ¶
type SpansMalformed struct { // DuplicateSpanID is when one or more spans in a trace have the same SpanId DuplicateSpanID atomic.Int64 // ServiceEmpty is when a span has an empty Service field ServiceEmpty atomic.Int64 // ServiceTruncate is when a span's Service is truncated for exceeding the max length ServiceTruncate atomic.Int64 // ServiceInvalid is when a span's Service doesn't conform to Datadog tag naming standards ServiceInvalid atomic.Int64 // PeerServiceTruncate is when a span's peer.service is truncated for exceeding the max length PeerServiceTruncate atomic.Int64 // PeerServiceInvalid is when a span's peer.service doesn't conform to Datadog tag naming standards PeerServiceInvalid atomic.Int64 // SpanNameEmpty is when a span's Name is empty SpanNameEmpty atomic.Int64 // SpanNameTruncate is when a span's Name is truncated for exceeding the max length SpanNameTruncate atomic.Int64 // SpanNameInvalid is when a span's Name doesn't conform to Datadog tag naming standards SpanNameInvalid atomic.Int64 // ResourceEmpty is when a span's Resource is empty ResourceEmpty atomic.Int64 // TypeTruncate is when a span's Type is truncated for exceeding the max length TypeTruncate atomic.Int64 // InvalidStartDate is when a span's Start date is invalid InvalidStartDate atomic.Int64 // InvalidDuration is when a span's Duration is invalid InvalidDuration atomic.Int64 // InvalidHTTPStatusCode is when a span's metadata contains an invalid http status code InvalidHTTPStatusCode atomic.Int64 }
SpansMalformed contains counts for reasons malformed spans have been accepted after applying automatic fixes
func (*SpansMalformed) String ¶
func (s *SpansMalformed) String() string
type Stats ¶
type Stats struct { // TracesReceived is the total number of traces received, including the dropped ones. TracesReceived atomic.Int64 // TracesFiltered is the number of traces filtered. TracesFiltered atomic.Int64 // TracesPriorityNone is the number of traces with no sampling priority. TracesPriorityNone atomic.Int64 // TracesPerPriority holds counters for each priority in position MaxAbsPriorityValue + priority. TracesPerSamplingPriority samplingPriorityStats // ClientDroppedP0Traces number of P0 traces dropped by client. ClientDroppedP0Traces atomic.Int64 // ClientDroppedP0Spans number of P0 spans dropped by client. ClientDroppedP0Spans atomic.Int64 // TracesBytes is the amount of data received on the traces endpoint (raw data, encoded, compressed). TracesBytes atomic.Int64 // SpansReceived is the total number of spans received, including the dropped ones. SpansReceived atomic.Int64 // SpansDropped is the number of spans dropped. SpansDropped atomic.Int64 // SpansFiltered is the number of spans filtered. SpansFiltered atomic.Int64 // EventsExtracted is the total number of APM events extracted from traces. EventsExtracted atomic.Int64 // EventsSampled is the total number of APM events sampled. EventsSampled atomic.Int64 // PayloadAccepted counts the number of payloads that have been accepted by the HTTP handler. PayloadAccepted atomic.Int64 // PayloadRefused counts the number of payloads that have been rejected by the rate limiter. PayloadRefused atomic.Int64 // TracesDropped contains stats about the count of dropped traces by reason TracesDropped *TracesDropped // SpansMalformed contains stats about the count of malformed traces by reason SpansMalformed *SpansMalformed }
Stats holds the metrics that will be reported every 10s by the agent. Its fields require to be accessed in an atomic way.
Use NewStats to initialise.
type StatsWriterInfo ¶
type StatsWriterInfo struct { Payloads atomic.Int64 ClientPayloads atomic.Int64 StatsBuckets atomic.Int64 StatsEntries atomic.Int64 Errors atomic.Int64 Retries atomic.Int64 Splits atomic.Int64 Bytes atomic.Int64 }
StatsWriterInfo represents statistics from the stats writer.
func (StatsWriterInfo) MarshalJSON ¶ added in v0.39.0
