DumbMonitor is a straightforward, open-source tool from DumbWareio designed to monitor websites. It allows users to track the status of specified URLs with a simple setup, featuring customizable check intervals and a minimalistic UI. Ideal for those who need a no-frills solution for website uptime monitoring, it runs easily via Docker and adheres to the “Dumb” design philosophy of simplicity and efficiency. In this step by step guide I will show you how to install DumbMonitor on your Synology NAS using Docker & Portainer.

STEP 1

Please Support My work by Making a Donation.

STEP 2

Install Portainer using my step by step guide. If you already have Portainer installed on your Synology NAS, skip this STEP. Attention: Make sure you have installed the latest Portainer version.

STEP 3

Log into Portainer using your username and password. On the left sidebar in Portainer, click on Stacks then + Add stack. Follow the instructions in the image below.

STEP 4

In the Name field type in dumbmonitor. Follow the instructions in the image below.

Note: Copy Paste the code below in the Portainer Stacks Web editor.

services:
  dumbmonitor:
    image: abite3/dumbmonitor:latest
    container_name: DumbMonitor
    security_opt:
      - no-new-privileges:true
    ports:
      - 8895:3000
    healthcheck:
      test: timeout 10s bash -c ':> /dev/tcp/127.0.0.1/3000' || exit 1
      interval: 10s
      timeout: 5s
      retries: 3
      start_period: 90s
    environment:
     WEBSITES: https://google.com, https://github.com, https://synology.com # Comma-separated list of websites to monitor
     CHECK_INTERVAL: 5000  # Backend check interval in milliseconds
     UI_REFRESH_INTERVAL: 5000 # Frontend refresh interval in milliseconds
     THEME: dark   # UI theme (light or dark)
    restart: on-failure:5

Note: Before you paste the code above in the Web editor area below, change the value for WEBSITES and add your own favorite websites with https:// at the beginning. Use a comma to separate the domains.

STEP 5

Scroll down on the page until you see a button named Deploy the stack. Click on it. Follow the instructions in the image below. The installation process can take up to a few minutes. It will depend on your Internet speed connection.

STEP 6

If everything goes right, you will see the following message at the top right of your screen: “Success Stack successfully deployed“.

STEP 7

Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.

STEP 8

The installation process can take up to a few seconds/minutes. It will depend on your Internet speed connection. Now open your browser and type in http://Synology-ip-address:8895 Your monitored websites at a glance!

Enjoy DumbMonitor!
