Expert guidance for configuring and deploying the OpenTelemetry Collector. Use when setting up a Collector pipeline, configuring receivers, exporters, or processors, deploying a Collector to Kubernetes or Docker, or forwarding telemetry to Dash0. Triggers on requests involving collector, pipeline, OTLP receiver, exporter, or Dash0 collector setup.

Common OTTL patterns

Rating: 100 (1 reviews)
Author: dash0

Set attributes

set(resource.attributes["k8s.cluster.name"], "prod-aws-us-west-2")

Drop telemetry by pattern

IsMatch(metric.name, "^k8s\\.replicaset\\..*$")

Drop stale data

time_unix_nano < UnixNano(Now()) - 21600000000000

Backfill missing timestamps

processors:
  transform:
    log_statements:
      - context: log
        statements:
          - set(log.observed_time, Now()) where log.observed_time_unix_nano == 0
          - set(log.time, log.observed_time) where log.time_unix_nano == 0

Filter processor example

processors:
  filter:
    metrics:
      datapoint:
        - 'IsMatch(ConvertCase(String(metric.name), "lower"), "^k8s\\.replicaset\\.")'

service:
  pipelines:
    metrics:
      receivers: [otlp]
      processors: [filter, batch]
      exporters: [debug]

Transform processor example

processors:
  transform:
    trace_statements:
      - context: span
        statements:
          - set(span.status.code, STATUS_CODE_ERROR) where span.attributes["http.response.status_code"] >= 500
          - set(span.attributes["env"], "production") where resource.attributes["deployment.environment"] == "prod"

service:
  pipelines:
    traces:
      receivers: [otlp]
      processors: [transform, batch]
      exporters: [debug]

Defensive nil checks

resource.attributes["service.namespace"] != nil
and
IsMatch(ConvertCase(String(resource.attributes["service.namespace"]), "lower"), "^platform.*$")
