From 983389e7200c7e04a57c21ac28b68577407b11be Mon Sep 17 00:00:00 2001 From: Maksim Kremenev Date: Sun, 29 Sep 2024 09:32:26 +0200 Subject: [PATCH] statsd: aggregate metrics from a chunk in batch Process all metrics in a chunk together. This is necessary for custom Prometheus-like histogram metrics. For example, when creating an `http_response_duration_seconds` metric with buckets 1...100 and a flush interval in Telegraf set to 30 seconds, the old version of the code would process each sample separately. If a flush interval occurred, only the processed metrics would be flushed with the current timestamp. The next metrics would be flushed in the following interval with a different timestamp (+30s), causing issues with histogram calculation. In the current version, all samples are processed together. --- plugins/inputs/statsd/statsd.go | 208 ++++++++++++++------------- plugins/inputs/statsd/statsd_test.go | 130 ++++++++++++----- 2 files changed, 201 insertions(+), 137 deletions(-) diff --git a/plugins/inputs/statsd/statsd.go b/plugins/inputs/statsd/statsd.go index 7a1224cc7581c..f788495901733 100644 --- a/plugins/inputs/statsd/statsd.go +++ b/plugins/inputs/statsd/statsd.go @@ -513,7 +513,8 @@ func (s *Statsd) udpListen(conn *net.UDPConn) error { case s.in <- input{ Buffer: b, Time: time.Now(), - Addr: addr.IP.String()}: + Addr: addr.IP.String(), + }: s.PendingMessages.Set(int64(len(s.in))) default: s.UDPPacketsDrop.Incr(1) @@ -541,6 +542,8 @@ func (s *Statsd) parser() error { start := time.Now() lines := strings.Split(in.Buffer.String(), "\n") s.bufPool.Put(in.Buffer) + // Each parsed line might pruduce multiple metrics. + metrics := make([]metric, 0) for _, line := range lines { line = strings.TrimSpace(line) switch { @@ -554,15 +557,18 @@ func (s *Statsd) parser() error { s.Log.Debugf(" line was: %s", line) } default: - if err := s.parseStatsdLine(line); err != nil { + ms, err := s.parseStatsdLine(line) + if err != nil { if !errors.Is(err, errParsing) { // Ignore parsing errors but error out on // everything else... return err } } + metrics = append(metrics, ms...) } } + s.aggregate(metrics...) elapsed := time.Since(start) s.ParseTimeNS.Set(elapsed.Nanoseconds()) } @@ -571,7 +577,7 @@ func (s *Statsd) parser() error { // parseStatsdLine will parse the given statsd line, validating it as it goes. // If the line is valid, it will be cached for the next call to Gather() -func (s *Statsd) parseStatsdLine(line string) error { +func (s *Statsd) parseStatsdLine(line string) ([]metric, error) { lineTags := make(map[string]string) if s.DataDogExtensions { recombinedSegments := make([]string, 0) @@ -601,12 +607,13 @@ func (s *Statsd) parseStatsdLine(line string) error { bits := strings.Split(line, ":") if len(bits) < 2 { s.Log.Errorf("Splitting ':', unable to parse metric: %s", line) - return errParsing + return nil, errParsing } // Extract bucket name from individual metric bits bucketName, bits := bits[0], bits[1:] + metrics := make([]metric, 0) // Add a metric for each bit available for _, bit := range bits { m := metric{} @@ -617,7 +624,7 @@ func (s *Statsd) parseStatsdLine(line string) error { pipesplit := strings.Split(bit, "|") if len(pipesplit) < 2 { s.Log.Errorf("Splitting '|', unable to parse metric: %s", line) - return errParsing + return nil, errParsing } else if len(pipesplit) > 2 { sr := pipesplit[2] @@ -641,14 +648,14 @@ func (s *Statsd) parseStatsdLine(line string) error { m.mtype = pipesplit[1] default: s.Log.Errorf("Metric type %q unsupported", pipesplit[1]) - return errParsing + return nil, errParsing } // Parse the value if strings.HasPrefix(pipesplit[0], "-") || strings.HasPrefix(pipesplit[0], "+") { if m.mtype != "g" && m.mtype != "c" { s.Log.Errorf("+- values are only supported for gauges & counters, unable to parse metric: %s", line) - return errParsing + return nil, errParsing } m.additive = true } @@ -658,7 +665,7 @@ func (s *Statsd) parseStatsdLine(line string) error { v, err := strconv.ParseFloat(pipesplit[0], 64) if err != nil { s.Log.Errorf("Parsing value to float64, unable to parse metric: %s", line) - return errParsing + return nil, errParsing } m.floatvalue = v case "c": @@ -668,7 +675,7 @@ func (s *Statsd) parseStatsdLine(line string) error { v2, err2 := strconv.ParseFloat(pipesplit[0], 64) if err2 != nil { s.Log.Errorf("Parsing value to int64, unable to parse metric: %s", line) - return errParsing + return nil, errParsing } v = int64(v2) } @@ -719,11 +726,10 @@ func (s *Statsd) parseStatsdLine(line string) error { sort.Strings(tg) tg = append(tg, m.name) m.hash = strings.Join(tg, "") - - s.aggregate(m) + metrics = append(metrics, m) } - return nil + return metrics, nil } // parseName parses the given bucket name with the list of bucket maps in the @@ -808,107 +814,109 @@ func parseKeyValue(keyValue string) (key string, val string) { // aggregate takes in a metric.
