Uptime Kuma: Self-Hosted Server Monitoring tool on Linux

Advertisements

In this tutorial, we are going to look into a self hosted Server Monitoring Tool on Linux called Uptime Kuma. Uptime Kuma is a free and open source self-hosted server and website monitoring tool aimed to offer a self-hosting alternative to "Uptime Robot" project. Uptime Robot is known to be one of the best monitoring service available today but it's not a self-hosted service so developers thought to replace it with a self-hosting service called Uptime Kuma. This also provides a lot more monitoring features than Uptime Robot. It is easy to install in any of the Linux distributions. We will see the steps to install in below section.

 

Important Features

  • It provides control over your data
  • It saves lot of time and effort
  • It is easy to use
  • It provides much more configurable option than any other monitoring tool
  • It is known to be self-sufficient
  • It allows you to monitor services internally in your private network

Step 3: Install Uptime Kuma

You can use multiple ways to install Uptime Kuma Server monitoring tool on Linux depending on your requirements and tools availability.

a) Using NodeJS

You need to first update your npm using sudo npm install npm -g command as shown below.

cyberithub@ubuntu:~$ sudo npm install npm -g
[sudo] password for cyberithub:

removed 13 packages, changed 74 packages, and audited 223 packages in 3s

14 packages are looking for funding
run `npm fund` for details

found 0 vulnerabilities

Then clone the package uptime kuma from GitHub using below git clone command.

cyberithub@ubuntu:~$ git clone https://github.com/louislam/uptime-kuma.git
Cloning into 'uptime-kuma'...
remote: Enumerating objects: 19267, done.
remote: Counting objects: 100% (19267/19267), done.

Resolving deltas: 100% (14359/14359), done.

Switch to uptime-kuma directory using cd uptime-kuma command.

cyberithub@ubuntu:~$ cd uptime-kuma

Then run the setup using npm run setup command as shown below.

cyberithub@ubuntu:~/uptime-kuma$ npm run setup

> uptime-kuma@1.19.0-beta.0 setup
> git checkout 1.18.5 && npm ci --production && npm run download-dist

Note: switching to '1.18.5'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

git switch -c <new-branch-name>

Or undo this operation with:

git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at 2ee83788 Update to 1.18.5
npm WARN config production Use `--omit=dev` instead.

Finally run the server using node server/server.js command as shown below.

cyberithub@ubuntu:~/uptime-kuma$ node server/server.js

Another option which is also the recommended one to install uptime kuma is through pm2 Node.js application. In this option, first you need to install pm2 on Linux using sudo npm install pm2 -g && pm2 install pm2-logrotate command as shown below.

cyberithub@ubuntu:~/uptime-kuma$ sudo npm install pm2 -g && pm2 install pm2-logrotate
[sudo] password for cyberithub:
npm WARN deprecated uuid@3.4.0: Please upgrade to version 7 or higher. Older versions may use Math.random() in certain circumstances, which is known to be problematic. See https://v8.dev/blog/math-random for details.

b) Using Docker

Another best option you have is to run the application as a docker container by using below docker command.

cyberithub@ubuntu:~$ sudo docker run -d --restart=always -p 3001:3001 -v uptime-kuma:/app/data --name uptime-kuma louislam/uptime-kuma:1
[sudo] password for cyberithub:

Then check the container running status by using sudo docker ps -a command as shown below.

cyberithub@ubuntu:~$ sudo docker ps -a
CONTAINER ID IMAGE                  COMMAND                CREATED       STATUS                      PORTS                   NAMES
