Ingest OpenTelemetry metrics
When ingesting OpenTelemetry metrics, the following rules and details apply.
Dynatrace ingestion metrics
The following Dynatrace-specific metrics can be useful when analyzing metrics ingestion issues.
|Number of accepted data points|
|Number of rejected data points|
dsfm:active_gate.metrics.ingest.otlp.datapoints.rejected.count provides a
reason dimension with additional details on why that particular metrics value was rejected. In the Dynatrace UI, you can filter, sort, and split by that dimension.
Typical reasons why metrics may be rejected by Dynatrace are:
Metrics sent with a cumulative aggregation temporality – please switch to delta aggregation
Metrics sent for histograms – histograms are currently not supported
