VDR.aiObservability & Monitoring Services
Instrumentation, dashboards and alerting that tell you what broke and where — not just that something did.
Most teams have monitoring and still find out about outages from customers. The gap is usually not tooling but instrumentation: metrics that measure the infrastructure rather than the user's experience, logs with no correlation ID, traces that stop at the service boundary. We fix the instrumentation first, then the dashboards on top of it.
We build on OpenTelemetry so the data stays portable, and we are comfortable in Prometheus, Grafana, Loki, Tempo, Jaeger, and the commercial backends — Datadog, Honeycomb, New Relic — including moving between them when the bill stops making sense.
What we build
How an engagement runs
Assess
We review what you emit today, what your on-call actually uses, and which past incidents your current setup would have missed.
Instrument
OpenTelemetry into the services that matter first, with trace context threaded across service and queue boundaries.
Define SLOs
Objectives written against user-visible behavior, with alerting rebuilt around burn rate instead of static thresholds.
Hand over
Dashboards, runbooks and alert routing documented, and your team walked through them until they own it.

Work with a software development company
DEV.co is a software development company with senior engineers across web, data, cloud, and AI development services. Observability Engineering work rarely arrives on its own — it comes attached to a product, a migration, or a platform, and we build all three.
