Frequently Asked Questions

What is Koder Observability?▼

A unified network monitoring platform. It deploys lightweight agents on client machines that perform network diagnostics and correlate them with browser-side timing. Results are aggregated centrally for fleet-wide visibility, alerting, and reporting.

How does the agent work?▼

The agent (koder-trace) runs as a background service. It performs scheduled diagnostics against configured targets and stores results locally. A JavaScript snippet captures browser timing. Data syncs to the central server when connectivity is available.

Does it work offline?▼

Yes. Local-first architecture with store-and-forward sync. All data stored locally in SQLite. When the server is unreachable, data accumulates and syncs automatically when connectivity returns. No data is ever lost.

What platforms are supported?▼

Agent: Linux (deb/rpm + systemd), Windows (MSI + Service), macOS (brew + launchd). Server: Linux. Browser probe: all modern browsers.

How lightweight is the agent?▼

~20 MB RAM, less than 1% CPU. Database uses 10-50 MB disk with default settings. Designed for low-resource machines and thin clients.

What notification channels are supported?▼

Email (SMTP), SMS (Twilio/Vonage), WhatsApp (Meta Business API), Telegram, Slack, Google Chat, Microsoft Teams, webhooks, and push notifications (Firebase).

Is it open source?▼

Yes. All components are MIT licensed. Source code available on Koder Flow.

Can I self-host it?▼

Absolutely. Designed for self-hosting. Minimum: single server with 4 vCPU, 8 GB RAM. Supports clustering with Raft consensus for HA.

How does browser correlation work?▼

A ~3 KB JavaScript snippet uses PerformanceObserver API to passively capture HTTP timing (DNS, TCP, TLS, TTFB) with zero performance impact. Data is sent to the local agent for correlation with network diagnostics.
