Developers and site reliability engineers work better together when production signals connect user outcomes to the code and deployments that shape them. Agree on reliability goals, instrument services consistently, attach change context where possible, and use incidents to drive specific engineering improvements.
What active telemetry means for developers and SREs
Here, “active telemetry” describes an ongoing engineering feedback loop: software is intentionally instrumented, its signals help teams understand production behavior, and what teams learn informs code, tests, configuration, or architecture changes. It is an editorial shorthand, not an established OpenTelemetry term.
OpenTelemetry is a vendor-neutral, open-source framework for instrumenting, generating, collecting, and exporting telemetry such as traces, metrics, and logs. It supplies APIs, SDKs, instrumentation libraries, and a Collector ecosystem; it is not, by itself, a complete observability backend. Teams still choose and operate a backend, and portability depends partly on how they configure exporters and use backend-specific features.

As the OpenTelemetry observability primer explains, observability is about understanding a system from the outside. Developers contribute implementation knowledge and instrumentation; SREs bring operational patterns and reliability objectives. Neither role can make the loop effective alone if signals lack context, ownership is unclear, or teams cannot act on what they learn.

Start with the user outcome, then define reliability
A service can be reachable while still failing to deliver what a user needs. Begin with important user journeys, then choose service-level indicators (SLIs) that measure relevant behavior—for example, whether a key request completes successfully and quickly enough for its intended use. Select indicators that reflect service behavior rather than simply measuring what is easiest to collect.
Set a service-level objective (SLO) to express the reliability target and its connection to organizational or business value. SLIs describe measured behavior; SLOs state the objective the team is working toward. Google’s SRE in the Cloud guidance describes SLI/SLO monitoring as a way to align developers and operators and track service health.
Keep the initial set small enough to guide decisions. For each indicator, agree on its definition, the service or journey it covers, and who is responsible for investigating meaningful changes. A shared goal gives developers and SREs a common frame for prioritizing reliability work.

Build a shared telemetry baseline
Use traces, metrics, and logs together
These signals answer different questions. Metrics help reveal trends and changes in service behavior; traces show how work moves across components; logs provide event-level detail. Together they can help teams move from noticing a problem to locating where it occurs and understanding what happened. Their usefulness depends on consistent naming, service attribution, and enough context to interpret signals across boundaries.
Agree on conventions for service identity, environment, and version, and apply them consistently across languages and components where supported. Make sure telemetry can be attributed to the system and team responsible for it. Unclear or conflicting names make cross-service investigation harder, even when each team’s local dashboards appear complete.
Instrument as part of application delivery
Build instrumentation into application design and delivery rather than waiting for an incident to expose an information gap. Standardized APIs, SDKs, and libraries can reduce inconsistent implementations across teams. Check that important user paths and service dependencies produce interpretable signals, and that the signals can be collected and exported through the organization’s chosen pipeline.
OpenTelemetry provides a common framework, but adopting it does not automatically guarantee complete coverage, compatible backends, or useful dashboards. Those outcomes depend on instrumentation choices, configuration, collection, and the operational practices around the data.
Connect production behavior to deployments
Telemetry is more actionable when teams can relate changes in service behavior to a release or deployment. Where the instrumentation and collection path support it, carry service, environment, version, and deployment context with the signals. Developers and SREs can then investigate telemetry alongside release history instead of treating production behavior and delivery activity as separate records.
The OpenTelemetry CI/CD Observability Special Interest Group is developing shared semantics for CI/CD telemetry and deployment attributes. Its work is ongoing; do not assume every CI/CD system, collector, or backend already implements a finished common standard. The project’s discussion connects delivery context with questions such as change lead time and recovery after failed deployments: OpenTelemetry’s update on its CI/CD Observability SIG.
Until conventions are supported throughout your toolchain, document which deployment attributes are emitted, where they are available, and what gaps remain. Avoid treating a missing or inconsistent deployment field as proof that a change did not affect a service.
Turn incidents and regressions into engineering work
When an SLO-relevant indicator shifts or an incident occurs, developers and SREs should examine the same signals and change context. SREs can contribute the operational pattern and user impact; developers can explain implementation details and recent changes. The investigation should end in a concrete decision—such as a code fix, a stronger test, a configuration change, or an architecture improvement—not merely a dashboard annotation.
This is a practical way to apply telemetry and SRE guidance, not a guarantee that instrumentation alone will resolve organizational friction. Teams also need clear service ownership, incident practices, and engineering capacity to make and deliver changes.

Choose an ownership and platform model that fits
Central support and team autonomy are not mutually exclusive. A platform group can provide a paved path—baseline configuration, supported SDKs, shared Collector patterns, onboarding, and self-service setup—while product teams remain responsible for their services’ behavior and instrumentation quality.
OpenTelemetry’s Kubernetes managed-telemetry blueprint discusses centrally managed telemetry paired with self-service tooling. It is guidance, not a universal architecture prescription. Compare approaches against the actual constraints your teams face:
| Decision | Questions to resolve |
|---|---|
| Ownership | Which defaults and collection paths should a platform team support, and which instrumentation and service-health decisions stay with each product team? |
| Portability | Does the instrumentation use a vendor-neutral framework such as OpenTelemetry? Which exporters or backend-specific features could make a later change harder? |
| Environment | How will collection and management work across Kubernetes, VMs, bare metal, and directly managed containers? |
| Operational context | Can teams relate telemetry to releases and deployments today, and which shared CI/CD conventions are still evolving? |
| Signal governance | Who sets conventions and reviews data volume, cardinality, access, retention, and collection practices? |
There is no single correct deployment approach. Tailor the design to environment, ownership, security, and operational constraints. OpenTelemetry’s guidance for non-Kubernetes environments addresses standardized agents, gateways, attribution, and governance for systems such as VMs, bare metal, and directly managed containers. Include these systems in the baseline rather than making Kubernetes the only well-supported path.

Excessive or high-cardinality data can burden storage, queries, and oversight, but there is no universal cost ratio that applies across architectures. Set organization-specific rules for what is collected and how it is managed; assess the trade-offs in the context of your environment and backend.
Quick Recap
A practical rollout sequence
- Choose a user journey. Identify a service behavior that matters to users and define an SLI that measures it.
- Agree on the objective. Set an SLO and name the service owner and operational partners responsible for acting on reliability signals.
- Apply instrumentation conventions. Use a supported SDK or library where appropriate, and align service identity, environment, and version attribution across components.
- Verify collection and interpretation. Confirm traces, metrics, and logs reach the selected backend with enough context to investigate behavior across service boundaries.
- Add delivery context where supported. Connect relevant version or deployment metadata to telemetry, while documenting gaps in toolchain support or shared semantics.
- Review a real operational event. Use a release, regression, or incident to test whether developers and SREs can jointly trace user impact to service behavior and decide on a specific improvement.
- Improve the paved path. Use repeated setup gaps to refine platform defaults, Collector patterns, onboarding, self-service configuration, and governance across all deployment environments.
