OpenTelemetry — 7 building blocks of effective observability: metrics, logs & traces | StarCloudIT
Services › Observability

OpenTelemetry & observability stack (metrics • logs • traces)

We standardize signals and speed up diagnosis: metrics, logs and traces in a single data model, the Collector for routing, semantic attributes and intentional sampling. Result: less noise, faster RCA and clear SLOs.

OpenTelemetry & observability stack — metrics, logs and traces with the Collector and OTLP
Diagram: SDK → Collector (processors/exporters) → storage & dashboards. One standard, many integrations.
Standardization

One data model

OTLP for metrics, logs and traces — easier correlation and less vendor lock-in.

Costs

Governance & control

Sampling, cardinality limits and retention policies keep storage costs in check.

Visibility

End-to-end tracing

Request path across microservices + user and release context.

SLOs

Success criteria

SLIs, SLO targets and error budgets — data-informed product decisions.

What we deliver with OpenTelemetry

From instrumentation to operations: consistent attributes, the Collector, signal correlation and SLO dashboards. We start with explainable methods and quick wins.

OpenTelemetry & observability stack — Collector architecture and OTLP flow
SDK → processors (sampling, batch, transform) → exporter(s) to selected backends.

Application instrumentation

SDKs and auto-instrumentation for popular languages. Shared attribute and tag conventions (e.g., service.name, http.target, db.system) so correlations are meaningful.

Collector & routing

Central Collector: batching, filtering, enrichment, head/tail sampling. Route to multiple backends without touching app code.

Metrics, logs & traces

One standard carries three signals. Link traces to metrics (exemplars) and tie events to releases and feature flags.

Dashboards & alerting

SLO dashboards, error budget burn-down, thresholds with seasonality. Incident priority by user impact.

Cost control

Cardinality reduction, trace sampling, retention policies and compression — cost visibility across ingest/retention/query stages.

7 building blocks of effective observability

1. Semantic attributes

Unified naming and tags enable cross-service correlations and reporting.

2. Intentional sampling

Head/tail sampling with conditions (errors, high latency) — savings without losing signal value.

3. Correlation

Join traces with metrics/logs, link to deploys and feature flags.

4. SLIs/SLOs

Quality contracts for services, error budgets and release decisions.

5. Cost governance

Cardinality limits, per-signal retention and query cost monitoring.

6. Security

RBAC, PII masking, TLS/OTLP, access auditing and compliance.

7. Operability

Runbooks, on-call, post-mortems and continuous threshold tuning.

Implementation plan (7–14 day pilot)

Fast impact and a foundation you can scale. Iterative delivery with transparent trade-offs.

Days 1–2

Discovery

Service & signal map, priorities and SLO goals. Pilot scope and risks.

Days 3–5

Instrumentation

SDK/auto-instrumentation, attributes and the Collector. Baseline dashboards.

Days 6–9

Correlation & alerts

Signal joins, thresholds and seasonality. Alerts routed to the right queues.

Days 10–14

Report & roadmap

Impact, costs, retention & sampling recommendations. Scale-up plan.

How we measure success

Shorter time-to-diagnose, fewer escalations, lower MTTR and reduced storage costs. Reports align outcomes to SLO targets, while error budgets guide release decisions.

FAQ — quick answers

Do we need to migrate current dashboards and agents?
Not always. The Collector can fan-out to multiple backends in parallel. We often start OTel alongside existing agents and simplify the stack gradually.
How do you control data costs?
Tail-based sampling on “interesting” traces, metric cardinality limits, per-signal retention and noise filtering in the Collector before storage.
On-prem or cloud?
Both. Data can remain in your infrastructure; we enable TLS, RBAC and access auditing with retention policies aligned to compliance.
How long is the pilot and what do we get?
Typically 7–14 days. You get working instrumentation, a Collector setup, first SLO dashboards, alerting and a cost report with retention/sampling recommendations.
