Monitoring that stays yours.

Matmon is a lightweight, Docker-first alternative to the big monitoring suites. Sensors, probes, alerts, wallboards and reports – running on your own host, with an optional cloud when you want reach.

Run it yourself

Everything you need to watch your stack

From a single Raspberry Pi to a fleet of sites – one clean interface, one clear signal.

Over 40 sensor types

Ping, HTTP, SNMP (v3 included), DNS, certificates, Docker, Proxmox, VMware, Synology, UPS, Windows and Linux health, SQL and your own scripts – with sensible default thresholds out of the box.

Probes and agents

Remote probes dial out to your primary, so a site behind NAT needs no open port. The agent runs as a Windows service or systemd unit on the machine it watches – and keeps itself up to date.

Alerts that stay

Alarms stay until someone acknowledges them and can be muted. Let a blip pass before it alarms, and escalate to the next person when nobody reacts – with per-channel thresholds and cooldowns.

Push, chat and e-mail

Notify by e-mail or webhook, with ready-made presets for ntfy, Pushover, Gotify, Telegram, Microsoft Teams, Slack and Discord – and a test button on every rule.

Power cuts, the moment they happen

Watch a UPS over its network card (SNMP) or on the USB port of your NAS (NUT): running on battery is critical at once, and a trap from the UPS makes Matmon look right away.

Maps and wallboards

Build a wallboard from gauges, graphs, lists, SLA and floor-plan widgets, roll whole subtrees or tags into one tile, and share a read-only link for the screen on the wall.

Syslog and SNMP traps

Collect the logs and traps of your switches, firewalls and servers in one place – on Matmon itself or on a probe next to the devices, which keeps them while your instance is away – search them live, and let a sensor raise an alarm when a device reports trouble.

Reports

A scheduled summary by e-mail and a customer-ready PDF audit report with uptime, problems and the events of the period.

An optional cloud

A dead-man switch for each instance, a public status page, a notification gateway and Full Access – operate a primary behind NAT straight from the browser.

The Matmon dashboard: sensor counts, the status bar and live sensorsThe Matmon dashboard: sensor counts, the status bar and live sensors

The dashboard – counts, the sensor status at a glance, highlighted sensors and every live value.

Matmon sensor tree with folders, hosts and sensor chipsMatmon sensor tree with folders, hosts and sensor chips

One tree for the whole estate – probes, folders, hosts and sensors with their live values.

Matmon sensor detail page with value cards, channels and a latency chartMatmon sensor detail page with value cards, channels and a latency chart

Every sensor with its channels, thresholds and statistics for the last hour, day and week.

Matmon Events page, Syslog tab: device messages and SNMP traps with severity, sender and programMatmon Events page, Syslog tab: device messages and SNMP traps with severity, sender and program

The central log – what switches, firewalls and servers report, and the SNMP traps of a UPS, in one live, searchable list (here from demo devices).

Matmon notification sender: a webhook with the ntfy preset, its address, method, headers and bodyMatmon notification sender: a webhook with the ntfy preset, its address, method, headers and body

A push sender in two clicks: pick the ntfy preset (or Pushover, Gotify, Telegram, Teams, Slack, Discord) and the request is filled in.

Matmon wallboard on a TV: health, open alerts, clock, latency and certificate widgetsMatmon wallboard on a TV: health, open alerts, clock, latency and certificate widgets

A wallboard built from widgets, on the screen on the wall through its read-only link.

Every page works on a phone: the menu becomes a drawer, tables become cards.

Up and running in three steps

Install it

Start the container on any Docker host or run the Windows setup, and create your admin on first launch – no external database needed.

Add sensors, probes and agents

Discover your network, pick sensors from the catalog, drop a probe at a remote site or an agent on a server.

Connect the cloud – if you like

Link to Matmon Cloud for a dead-man switch, a public status page and browser access to instances behind NAT.

Simple, honest pricing

The monitor is yours to self-host. A cloud plan is per instance.

Run it yourself

On any Docker host or as a Windows service. Everything Matmon keeps – configuration, history and the cloud link – stays on your machine.

Open http://your-host:8099 afterwards and create your admin account.

Updates itself. With the Docker socket mounted, or as a Windows service, Matmon installs new versions on request or in a nightly window – and goes back if the new one does not come up.

Or start with the Cloud

docker-compose.yml
services:
  matmon:
    image: ghcr.io/real-ttx/matmon:latest
    container_name: matmon
    restart: unless-stopped
    ports:
      - "8099:8099"
    volumes:
      - matmon-data:/app/data
      # lets Matmon update itself (System > Updates)
      - /var/run/docker.sock:/var/run/docker.sock

volumes:
  matmon-data:
    name: matmon-data
then
docker compose up -d
docker run
docker run -d --name matmon \
  --restart unless-stopped \
  -p 8099:8099 \
  -v matmon-data:/app/data \
  -v /var/run/docker.sock:/var/run/docker.sock \
  ghcr.io/real-ttx/matmon:latest

The socket line lets Matmon pull its new image and replace its own container. It gives the container control over Docker on that machine – leave it out where that is not acceptable, and update with docker compose pull instead.

Download the setup Online setup (small download)

64-bit Windows. Matmon runs as the Windows service Matmon, with an icon in the notification area, and updates itself. The online setup fetches the newest build during setup and checks its checksum and signature first. Without a setup: matmon-windows-x64.zip · newest features: nightly channel.

unattended (software distribution)
.\MatmonSetup-x64.exe /silent /port=8099 /firewall
