Description
When routing using a datapoint context, the routed Metric is missing IsMonotonic and AggregationTemporality (when routing using the default context, it works fine).
Trying to forward them to a Datadog Exporter fails due to that.
Steps to Reproduce
Config:
receivers:
otlp:
protocols:
http:
endpoint: 0.0.0.0:4318
exporters:
debug:
verbosity: detailed
connectors:
routing/stage:
match_once: true
table:
# outbound metrics have undefined/default IsMonotonic and AggregationTemporality
- condition: 'attributes["stage"] == "production"'
context: datapoint
pipelines: [metrics/prod]
# outbound metrics have proper IsMonotonic and AggregationTemporality
# - statement: 'route()'
# pipelines: [metrics/prod]
service:
telemetry:
logs:
level: debug
pipelines:
metrics/in:
receivers: [otlp]
exporters: [routing/stage]
metrics/prod:
receivers: [routing/stage]
exporters: [debug]
Expected Result
Expecting to see this in logs:
Metric #7
Descriptor:
-> Name: app_user_logins_total
-> Description: The number of users login into the Klarna app.
-> Unit:
-> DataType: Sum
-> IsMonotonic: true
-> AggregationTemporality: Cumulative
Actual Result
Seeing this in logs:
Metric #7
Descriptor:
-> Name: app_user_logins_total
-> Description: The number of users login into the Klarna app.
-> Unit:
-> DataType: Sum
-> IsMonotonic: false
-> AggregationTemporality: Unspecified
When forwarding this to a Datadog Exporter we get:
2025-01-16T10:39:36.757Z debug [email protected]/metrics_translator.go:854 Unknown or unsupported aggregation temporality {"kind": "exporter", "data_type": "metrics", "name": "datadog/exporter", "component": "metrics translator", "metric name": "app_user_logins_total", "aggregation temporality": "Unspecified"}
