Resources Ingester Telemetry

This document describes the OpenTelemetry metrics and assets for the Resources Ingester.

For general setup instructions, see the OpenTelemetry Configuration guide.

Telemetry Assets

• dashboards/resources-ingester-overview.dashboard.json: Grafana dashboard with panels for resource throughput, drop rates, queue depth, and batch flush performance.
• collector/otel-collector-config.yaml: Minimal OpenTelemetry Collector configuration.

Metrics Reference

Naming note

In Prometheus, metric names are normalized with underscores (e.g., resources_ingester_resources_received), and counters typically include the _total suffix.

Metrics Table

Metric	Type	Unit	Description	PromQL example
resources_ingester.resources.received	Counter	count	Number of resources accepted by router input path.	sum(rate(resources_ingester_resources_received_total[5m]))
resources_ingester.resources.dispatched	Counter	count	Number of resources forwarded to the ingester handler.	sum(rate(resources_ingester_resources_dispatched_total[5m]))
resources_ingester.resources.dropped	Counter	count	Dropped resources in router/ingester paths.	sum by (reason) (rate(resources_ingester_resources_dropped_total[5m]))
resources_ingester.batch.flush.duration_seconds	Histogram	seconds	Duration of a batch flush cycle.	histogram_quantile(0.95, sum by (le) (rate(resources_ingester_batch_flush_duration_seconds_bucket[5m])))
resources_ingester.batch.flush.size	Histogram	records	Number of records per flush.	histogram_quantile(0.95, sum by (le) (rate(resources_ingester_batch_flush_size_bucket[5m])))
resources_ingester.db.insert.rows	Counter	rows	Number of rows inserted by successful batch writes.	sum(rate(resources_ingester_db_insert_rows_total[5m]))
resources_ingester.db.insert.failure	Counter	count	Batch insert failures.	sum by (type) (increase(resources_ingester_db_insert_failure_total[1h]))
resources_ingester.queue.depth	Gauge	count	In-memory queue buffered job count.	max(resources_ingester_queue_depth)
resources_ingester.record_channel.depth	Gauge	count	In-memory record channel buffered item count.	max(resources_ingester_record_channel_depth)
