Hexcovery Documentation

Hexcovery is a European observability platform that collects, stores, and visualizes metrics, logs, and traces from your infrastructure and applications — in one place, queryable with one language.

Why Hexcovery

  • All-in-one: metrics, logs, traces, alerting, and dashboards in a single platform.
  • Simple pricing: €0.35/GB ingested. Unlimited users. No per-host or per-service fees.
  • European: your data stays in Europe. No CLOUD Act exposure.
  • OpenTelemetry native: standard OTLP protocol. No vendor lock-in.

Start here

  • Quick Start — get data flowing in a few minutes.
  • Core concepts — entities, signals, services, and Projects: the model the whole UI is built on.
  • Send your data — the agent, OpenTelemetry SDKs, infrastructure metrics, cron heartbeats.
  • Explore in the dashboard — the built-in pages for hosts, Kubernetes, logs, services, traces, and more.
  • Query Language (OQL) — query everything with one SQL-inspired language.

The agent runs on your servers (Linux daemon or Kubernetes DaemonSet) and collects system + Kubernetes metrics and host logs. Your applications send traces, logs, and metrics via OpenTelemetry SDKs, and OTel receivers ship metrics from infrastructure like PostgreSQL, Redis, and Kafka. Everything arrives over the standard OTLP protocol, is stored per-tenant, and is queried with OQL.
