Sentinela

Know the moment a host, service or link goes down.

A lean NOC, without the complexity of enterprise tools, that runs inside your network. Single Windows binary, no cloud, no per-machine agent. It discovers your devices, watches uptime and latency, and alerts over e-mail, WhatsApp and Telegram before the customer calls to complain.

What it does

Auto-discovery

Sweeps your subnet and suggests the targets — PCs, servers, switches, routers, printers.

Uptime & MTTR

Per-target availability over 24h/7d/30d, real downtime, longest outage and mean time to recovery.

Animated network map

Live NOC-style view: pulses follow each ping, whatever is down glows orange.

Real SNMP

CPU, RAM, disk and per-interface traffic (in/out bps) from switches and servers that expose SNMP.

Alerts that don't spam

Anti-flap hysteresis, common-cause storm suppression, target dependencies and maintenance windows.

Multi-channel

E-mail, WhatsApp, Telegram and generic webhook (Slack/Teams/Discord/ntfy). Escalation if nobody acknowledges.

Weekly report

Availability digest by e-mail, worst-first, with the biggest outages of the week.

One binary, on-prem

Nothing to install. Runs as a Windows service. Your data never leaves your network.

How the license works

Offline, no phone-home

The license is a signed file (Ed25519) verified locally. Sentinela never needs the internet to validate it.

Node-locked

Each license can be bound to a specific PC — if it leaks, it activates nowhere else. It just falls back to demo (5 targets).

Never bricks

With no license it does not lock up: it keeps monitoring up to 5 devices. The license only raises the cap.
