Metrics and attributes

Learn which metrics OBI collects and how to configure metric and attribute collection for your environment.

Overview

OBI collects HTTP and gRPC metrics by default. OBI does not collect runtime metrics at this time. You can also enable network-level metrics to gain visibility into low-level traffic patterns across workloads.

For a full overview of metrics supported by OBI, see the https://opentelemetry.io/docs/zero-code/obi/metrics/ OpenTelemetry OBI metrics documentation.

HTTP and gRPC metrics

OBI automatically captures high-level HTTP and gRPC metrics, including common request and response metadata. These metrics provide insight into service performance, latency, throughput, and error rates across your instrumented applications.

To learn more about available metric types, see OBI metrics reference.

Network-level metrics

OBI can optionally provide network-level metrics derived from kernel-level eBPF observations. These metrics help monitor traffic patterns, protocol behavior, and network interactions that may not be visible through HTTP or gRPC instrumentation alone.

For details about supported network signals, see the network metrics section.

Configure metric collection

You can configure how OBI collects and exports metrics, including export targets and common metric settings. This allows you to control what data is emitted and where it is delivered.

For configuration details, see common metrics configuration.

Metric attributes

OBI attaches a set of attributes to each metric to provide context such as protocol, endpoint, status, and other identifiers. These attributes help segment and analyze telemetry in downstream systems.

For the list of metric attributes, see OBI metric attributes.

Configure attribute collection

OBI lets you control which attributes are collected or filtered. This helps reduce ingest volume and ensures only relevant attributes are attached to your metrics and traces.

For attribute configuration options, see metrics and traces attribute configuration.

Internal metrics

OBI can report internal operational metrics in Prometheus format. These metrics provide visibility into OBI’s internal components, performance, and health.

For the full list of internal metrics, see internal metrics reference.
