For more information, see the OpenTelemetry project documentation for the [Prometheus receiver](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/receiver/prometheusreceiver). ## Setup{% #setup %} Add the following lines to your Collector configuration: ```yaml receivers: prometheus: config: scrape_configs: - job_name: 'otelcol' scrape_interval: 10s static_configs: - targets: ['0.0.0.0:8888'] ``` {% alert level="warning" %} If you have a Datadog Agent running on the same host as an OpenTelemetry Collector or DDOT Collector that uses a Prometheus receiver to scrape Collector health metrics, make sure the Agent's [OpenMetrics integration](https://docs.datadoghq.com/integrations/openmetrics.md) is either turned off or scraping a different endpoint than the Collector health metrics endpoint. Otherwise, both the Agent and Collector scrape the same endpoint, resulting in duplicate Collector health metrics. {% /alert %} ## Data collected{% #data-collected %} | OpenTelemetry Metric | Description | | ------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------- | | `otelcol_process_uptime` | Uptime of the process | | `otelcol_process_memory_rss` | Total physical memory (resident set size) | | `otelcol_exporter_queue_size` | Current size of the retry queue (in batches) | | `otelcol_exporter_sent_spans` | Number of spans successfully sent to destination | | `otelcol_exporter_send_failed_metric_points` | Number of metric points in failed attempts to send to destination | | `otelcol_exporter_send_failed_spans` | Number of spans in failed attempts to send to destination | | `otelcol_process_cpu_seconds` | Total CPU user and system time in seconds | | `otelcol_receiver_refused_spans` | Number of spans that could not be pushed into the pipeline | | `otelcol_exporter_queue_capacity` | Fixed capacity of the retry queue (in batches) | | `otelcol_receiver_accepted_spans` | Number of spans successfully pushed into the pipeline | | `otelcol_exporter_sent_metric_points` | Number of metric points successfully sent to destination | | `otelcol_exporter_enqueue_failed_spans` | Number of spans failed to be added to the sending queue | | `otelcol_scraper_errored_metric_points` | Number of metric points that were unable to be scraped | | `otelcol_scraper_scraped_metric_points` | Number of metric points successfully scraped | | `otelcol_receiver_refused_metric_points` | Number of metric points that could not be pushed into the pipeline | | `otelcol_receiver_accepted_metric_points` | Number of metric points successfully pushed into the pipeline | | `otelcol_process_runtime_heap_alloc_bytes` | Bytes of allocated heap objects (see 'go doc runtime.MemStats.HeapAlloc') | | `otelcol_process_runtime_total_alloc_bytes` | Cumulative bytes allocated for heap objects (see 'go doc runtime.MemStats.TotalAlloc') | | `otelcol_exporter_enqueue_failed_log_records` | Number of log records failed to be added to the sending queue | | `otelcol_processor_batch_timeout_trigger_send` | Number of times the batch was sent due to a timeout trigger | | `otelcol_exporter_enqueue_failed_metric_points` | Number of metric points failed to be added to the sending queue | | `otelcol_process_runtime_total_sys_memory_bytes` | Total bytes of memory obtained from the OS (see [the Go docs for `runtime.MemStats.Sys`](https://pkg.go.dev/runtime#MemStats.Sys)) | | `otelcol_processor_batch_batch_size_trigger_send` | Number of times the batch was sent due to a size trigger | | `otelcol_exporter_sent_log_records` | Number of log records successfully sent to destination | | `otelcol_receiver_refused_log_records` | Number of log records that could not be pushed into the pipeline | | `otelcol_receiver_accepted_log_records` | Number of log records successfully pushed into the pipeline | ##
