Thanks to all the great work being done to get Xymon on Github lately, I created a fork where I refactored Xymon HTML output to be HTML 5 compliant. I had to do this in my own projects years ago, so I "put the band back together”.

This is not a theme, this is a complete purge of Web 1.0 table based layouts embedded in the .c to a modern HTML5 compliant, responsive (aka mobile) interface. (I did however implement proper CSS themeing for easy customization).

Release Details:
https://github.com/spiderr/xymon/releases

Code:
https://github.com/spiderr/xymon/tree/html5-bootstrap

EL9 rpm build:
https://github.com/spiderr/xymon/releases/download/v5.0.1/xymon-5.0.1-0.el9.tera.x86_64.rpm

Snippet from the release notes:

100% UI changes, 0% everything else. My hard rule was every daemon, protocol, data format, CGI API, URL, and query string is identical to 4.3.30. Scripts, bookmarks, and integrations will not notice the difference. The only thing that changed is the HTML that comes out of the CGIs and page generator. This is a large refactor so I presumptuously dubbed it 5.0, because... HTML5 + Bootstrap 5 = Xymon 5...

I could say a lot more, but the release page has almost all changes well documented.

Here are some screenshots:

Hey,

wow – it looks like it was a hell of a lot of work!

Working with and using Xymon since 2006, I’ve installed it several times on various linux os’es, and I’m using it at home also.

Currently we’re stuck with 4.3.30, monitoring our infrastructure persisting of around 1000 devices, but with a lot of own scripts on your Xymon installation.

Seeing your post here leads me to create another virtual machine to install your -let me say- Xymon variant.

The install went through straight forward; did this on OracleLinux 10.1 without any problems, not using any OracleLinux-foreign repos.

Your UI redesign is, indeed, a big change and, if I can tell it from my side only, I need to become familiar with this. It’s different, more modern, and I’ll see whether it’s more usable (for me).

I respect your work that went into it!

I’ll work the next days with it.

Thank you for your work!

Regards

Christian

Glad to hear the build worked! I have been using Rocky 9 for my development, so that is a small adjustment to OL10.

Please let me know your thoughts. Every feature and URL from 4.3.30 should work identical on 5.0.1 - if not, please ask.  It was a little disorienting at first after decades of the interface. Now I am 😡 when I have to use the old interface. 

Like you, I have been using Xymon since 2006, and I use it on multiple installs with similar device counts. Most useful for me is the new CSS Color selector. It is a big help if you have Group Pages of many devices and I want to see "just blue rows" for example. It is simple CSS, so back end code was needed.

I am curious, do you use ACK or Critical Systems? I have never used them because the interface seemed to hard, but now I am more interested with the easier forms.
