Built like a constellation

Galaxy view

Every node is a star. Green means healthy, amber means warnings, red means critical. Your whole fleet, one glance.

History stays on your nodes

Agents keep full metric history locally in an embedded database. The platform requests exactly the range you look at — nothing else leaves your server.

No open ports

Agents connect outbound over WebSockets. No inbound firewall rules, no exposed dashboards on your servers.

Severity-based alerts

Warning at 80% disk usage, critical at 90%. Every module ships with sensible default alerts, evaluated on the node itself.

Service auto-detection

The agent discovers what runs on the node — MySQL, ClickHouse, Apache2, Nginx — and starts collecting the right metrics automatically.

Self-updating agents

Publish a release on the platform and agents upgrade themselves safely, with checksum verification and automatic restart.

Modules included today

Each module knows how to detect its service, which metrics to collect, and ships with default warning and critical thresholds.
