Concepts

Before adding hosts, the five concepts that everything else rests on:

• Architecture

  How data travels from agent/collector through receiver, Redis, workers, into the DB and back to the frontend.

• Status & state model

  OK / WARNING / CRITICAL / NO_DATA / UNKNOWN, soft/hard, severity order, retry interval.

• Profiles & checks

  Two-tier model: profiles describe the device, profile-checks describe what's monitored.

• License tiers

  Community, Pro, Enterprise — feature matrix and activation workflow.

• Glossary

  All terms in one place.
