Overview
This document lists some of the metrics available from Observability Pipelines. You can:
- Create your own dashboards, notebooks, and monitors with these metrics.
- Use Metrics Summary to see metadata and tags available for the metrics. You can also see which dashboards, notebooks, monitors, and SLOs are using those metrics.
See Getting Started with Tags for more information on how to use tags to group metrics by specific pipelines, Workers, and components.
Estimated usage metric
- Observability Pipelines ingested bytes
- Metric:
datadog.estimated_usage.observability_pipelines.ingested_bytes - Description: The volume of data ingested by Observability Pipelines. See Estimated Usage Metrics for more information.
Pipeline metrics
- Bytes in per second
- Metrics:
pipelines.host.network_receive_bytes_total - Description: The number of events the pipeline receives per second.
- Bytes out per second
- Metrics:
pipelines.host.network_receive_bytes_total - Description: The number of bytes the pipeline receives per second.
Component metrics
These metrics are available for sources, processors, and destinations.
- Bytes in per second
- Metric:
pipelines.component_received_bytes_total - Description: The number of bytes the component receives per second.
- Available for: Sources, processors, and destinations.
- Bytes out per second
- Metric:
pipelines.component_sent_events_total - Description: The number of bytes the component sends to the destinations.
- Available for: Sources, processors, and destinations.
- Events in per second
- Metric:
pipelines.component_received_event_bytes_total - Description: The number of events the component receives per second.
- Available for: Sources, processors, and destinations.
- Events out per second
- Metric:
pipelines.component_sent_event_bytes_total - Description: The number of events the component sends to the destinations.
- Available for: Sources, processors, and destinations.
- Errors
- Metric:
pipelines.component_errors_total - Description: The number of errors encountered by the component.
- Available for: Sources, processors, and destinations.
- Data dropped intentionally or unintentionally
- Metric:
pipelines.component_discarded_events_total - Description: The number of events dropped. Note: To break down this metric, use the
intentional:true tag to filter for events that are intentionally dropped or the intentional:false tag for events that are not intentionally dropped. - Available for: Sources, processors, and destinations.
- Timed out events
- Metric:
pipelines.component_timed_out_events_total - Description: The number of events that waited more than 5 seconds to be sent to the first processor and resulted in a HTTP 503 error. This could happen when delivery of events are blocked.
- Available for: HTTP-based sources that have a configured timeout, such as the Datadog Agent.
- Timed out requests
- Metric:
pipelines.component_timed_out_requests_total - Description: The number of requests that timed out for sources that send events to the Worker in batches using HTTP requests.
- Available for: HTTP-based sources that have a configured timeout, such as the Datadog Agent.
- Utilization
- Metric:
pipelines.utilization - Description: The component’s activity. A value of
0 indicates an idle component that is waiting for input. A value of 1 indicates a component that is never idle, which means that the component is likely a bottleneck in the processing topology that is creating backpressure, which might cause events to be dropped. - Available for: Processors and destinations.
Buffer metrics (when buffering is enabled)
Track buffer behavior with these additional metrics:
pipelines.buffer_size_events- Number of events currently in the buffer.
pipelines.buffer_size_bytes- Number of bytes currently in the buffer.
pipelines.buffer_received_events_total- Cumulative number of events written to the buffer.
pipelines.buffer_received_event_bytes_total- Cumulative number of bytes written to the buffer.
pipelines.buffer_sent_events_total- Cumulative number of events read from the buffer and sent downstream.
pipelines.buffer_sent_event_bytes_total- Cumulative number of bytes read from the buffer and sent downstream.
pipelines.buffer_discarded_events_total- Cumulative number of events dropped by a buffer.
pipelines.source_buffer_utilization- Histogram of event count in a source’s buffer. Sources ingest events, then write them to this buffer.
pipelines.source_buffer_utilization_level- Current event count in a source’s buffer. Sources ingest events, then write them to this buffer.
pipelines.source_buffer_utilization_mean- The exponentially weighted moving average (EWMA) of the number of events in the source’s buffer.
pipelines.source_buffer_max_size_events- A source’s maximum buffer size, defined as the number of events.
pipelines.transform_buffer_utilization- Histogram of event count in a processor’s buffer. Processors pull from this buffer, transform the event, and then send it downstream.
pipelines.transform_buffer_utilization_level- Current event count in a processor’s buffer. Processors pull from this buffer, transform the event, and then send it downstream.
pipelines.transform_buffer_utilization_mean- The exponentially weighted moving average (EWMA) of the number of events in the processor’s buffer.
pipelines.transform_buffer_max_size_events- A processor’s maximum buffer size, defined as the number of events.
