Server Monitor Engine
Real-time performance monitoring for your Hytale server.
Know exactly what's happening — before your players do.

SELF-HOSTED | 
PAID SUBSCRIPTIONSME is a self-hosted monitoring solution — everything runs on your server, your infrastructure, your rules. You own the data, control the ports, choose your Prometheus instance, and configure everything to your needs. No external SaaS, no third-party telemetry, no vendor lock-in.
However, an active subscription through BuiltByBit is required to unlock Dashboard, Prometheus integration, and all advanced features.
If your subscription expires, Prometheus stops sending metrics and the dashboard becomes unavailable.
Why Server Monitor Engine?Running a Hytale server without monitoring is flying blind. When TPS drops, memory leaks, or GC storms hit, you need answers now — not after your players have already left.
Server Monitor Engine (SME) gives you a professional-grade monitoring stack with zero external setup for the free tier and Prometheus-powered historical analysis for Pro users.
Features
Real-Time TPS TrackingTrack your server's ticks per second with millisecond precision. See current TPS, tick duration, and rolling percentiles (P95/P99) at a glance. Never wonder "is my server lagging?" again.
Pro DashboardA dark-theme, responsive SPA that runs directly on your server. No external tools needed.
- Sparkline KPI cards with 30-min trends
- Time-series charts powered by Prometheus
- Health Score (0-100) weighted across TPS, latency, heap, GC, and CPU
- Anomaly detection with visual alerts
- Today vs Yesterday overlay comparisons
Plugin Ecosystem DashboardSME isn't just about server health. When you install other Miilhozinho's Mods plugins, their dashboards appear automatically as new tabs.
| Tab | Plugin | What You See |
|---|---|---|
| Server | SME | TPS, Memory, CPU, GC, Threads |
| Arena Waves Engine | AWE | Active sessions, players, enemies, waves |
| Events Schedule Engine | ESE | Scheduled events, queues, phase transitions |
More plugins = more visibility. No configuration needed.
Prometheus IntegrationExport all 25+ metrics to Prometheus for long-term storage, alerting, and Grafana dashboards.
SME does NOT include or run a Prometheus instance. You must install and maintain your own Prometheus server. This is an external dependency that you are responsible for setting up before using Pro features.
Two modes — pick what fits your infrastructure:
- Pull: Prometheus scrapes SME's /metrics endpoint
- Push: SME sends metrics via Remote Write (great for NAT/firewalled servers)
Both modes export identical metrics. Switch anytime.

Pricing — Recurring SubscriptionSME is a paid plugin with a recurring subscription through BuiltByBit. All core features — Dashboard, Prometheus, historical charts, plugin tabs — require an active subscription.
Prometheus stops sending metrics immediately. The dashboard becomes unavailable (returns 403). The JSON API degrades to 4 basic metrics only. Your monitoring goes dark until you renew.

Quick Start- Purchase SME on BuiltByBit — after your purchase, you will receive full setup instructions via platform chat and your License Key via HyLicense Portal.
- Install the plugin — drop ServerMonitorEngine.jar into your server's mods/ folder. Make sure Nitrado:WebServer is also installed.
- Start the server and run the command:
Code:/sme license set <licenseKey> - Open the Dashboard at http://<your-server>:7003/com.miilhozinho/ServerMonitorEngine
Full documentation will be sent via BuiltByBit chat after your purchase.
The message includes step-by-step Prometheus setup and configuration guide.
25+ Metrics at Your Fingertips| Category | Metrics |
|---|---|
| TPS & Ticks | Current TPS, tick duration, min/max/avg/P95/P99 |
| JVM Memory | Heap used/committed/max, non-heap used/committed |
| Garbage Collection | Collection count & time per collector |
| Threads | Current, peak, daemon, per-state breakdown |
| CPU | Process load, system load |
| System | Uptime, classes loaded/unloaded, host RAM usage |
All metrics use the Prometheus-standard prefix hytale_service_monitor_ and are queryable in PromQL.
FAQMinimal impact. Metric collection runs on a configurable interval (default 5s) and the data structures are optimized for concurrent reads. The dashboard is a lightweight SPA served by Nitrado:WebServer — no additional HTTP server is spawned.
Not for the free tier. Free works entirely from in-memory data. Pro requires Prometheus for historical charts, but setup takes under 5 minutes with our step-by-step guide in the Technical Documentation.
Prometheus stops sending metrics and the dashboard returns 403 Forbidden. The JSON API degrades to 4 basic metrics. Your server keeps collecting metrics internally, so when you renew your subscription everything restores instantly — no restart needed, no data gap. But while expired, you have no dashboard and no Prometheus.
Absolutely. SME exposes standard Prometheus metrics. Point Grafana at your Prometheus instance and build any dashboard you want. The built-in dashboard is just a convenient default.
Only plugins that are specifically built to send metrics to SME will appear as tabs on the dashboard. Not every plugin shows up — it must implement the SME Metrics API to report its data correctly.
