Create an alarm system when Website has problems with Uptime Kuma

In the previous post, I introduced free systems to help monitor whether the Website is down or has problems, if the Website is down, you will receive a warning about Email or Telegram, SMS… If you do not want to use the Website, 3rd party, you can create your own alert system with Uptime Kuma’s Docker.

Install Uptime Kuma to warn when the Website has a Downtime network failure

Surely Webmaster or Admin will be very headache if the Website has problems for a long time without you noticing. The best solution is to build an alert system when the Website is in error, inaccessible, there will be a message sent to you.

The previous post I introduced 3 ways to warn the website is down, but using a 3rd party system and not much tweaking. Today I will show you how to create an alarm system when Website has problems with Uptime Kuma with scan frequency 20 seconds/timehelping you promptly detect when the Website is no longer accessible.

How to use Uptime Kuma to send messages to Telegram when Website is Down

After installing Uptime Kuma, you need to create an account to manage.

Then access the main interface of Uptime Kuma, select

Enter the following information:

• Monitor Type: HTTP(s)
• Friendly Name: Name your Website
• URL: Website address to track
• Heartbeat Interval (Check every 20 seconds): Checking time, at least 20 seconds/time. In my opinion, 20 seconds should be beautiful
• Retries: number of times to recheck when Website is down, should be left 0 to try continuously until the Website is alive again
• Heartbeat Retry Interval (Retry every 20 seconds): number of seconds per retry when Website is Down, should be left 20

Next, click on the button Setup Notificationto configure the alert feature about Telegram.

You open Telegram, find BotFather: @BotFather or go to this path: https://t.me/BotFather

Press the button Start

In turn, type the following command into the Father bot:

Click on the link t.me/xxxxxxxxxxxx that the bot gives you (4), click the Start button to chat with your bot
