Zabbix: better “Disk space usage” graphs for Windows systems
Posted by jpluimers on 2018/01/09
The default [WayBack] Zabbix Disk space usage graph (named Disk space usage {#FSNAME}) for Windows looks like this:
Total disk space on C:
What I want is a graph over time. Based on that, I can start working on different triggers than the default “less than 20% free space available“, for instance:
- [WayBack] A better way to monitor diskspace with Zabbix | Guy Van Sanden
- [WayBack] Monitoring Disk space usage – ZABBIX Forums
So I want graphs similar to the CPU load (in the graph itself called Processor load) graph which looks like this:
CPU load (a.k.a. Processor load) is actually graphed “over time”
It is part of the Graph prototypes for the Template OS Windows discovery list Mounted filesystem discovery:
For now I’ve added this graph prototype as Line chart with 95th percentile:
If that work, I can start working on the triggers:

337 MB of source and utils in 2,308 Files, 910 Folders before you build (not counting 3rd party source UberBuild downloads).
It’s a start, with much to come.It will get easier now that UberBuild is clean.
I will be updating the docs and website in the next few days.
Special thanks …
I already see room for improvement (such as a setup screen for extra compilers such as Delphi and Free Pascal to keep folks out of shell scripts and from hunting for help in the documentation).

OpenSuSE on ODROID? Maybe one day I get to researching that
Posted by jpluimers on 2018/01/01
For my research list (thanks Mariusz Fik @Fisiu):
- [WayBack] How To compile a custom Linux kernel for your ARM device · umiddelb/armhf Wiki · GitHub
- [WayBack] January 2016 | ODROID Magazine on page 10 of the [WayBack] Magazine PDF with article title “Linux Kernel Compilation: How to Customize Your Operating System”
- [Archive.is] Linux for Amlogic Meson: start [linux-meson]
- [WayBack] Gmane Loom (which for a time showed as “ArchivedAt Nothing found – bye”), same for these:
Actually: this was more of a reminder checking out if someone else by now has made OpenSuSE Tumbleweed builds for ODROID (:

- Jeroen Pluimers @jpluimers: @Fisiu because of http://comments.gmane.org/gmane.linux.suse.arm/1547 … and I think you’re the same person.
- Mariusz Fik @Fisiu: @jpluimers That’s correct :)
- [Archive.is] Message: @Fisiu @jpluimers According to http://j.mp/2gxZ5Dc #odroid C1 should be supported by #linux 4.8. Please check updates: http://j.mp/2hCsfpW

htop – an interactive process viewer for Unix
Posted by jpluimers on 2017/12/25
Great tool: [WayBack] htop – an interactive process viewer for Unix because it’s both interactive and supports a wide range of OSes: Linux, FreeBSD, OpenBSD and Mac OS X.
Thanks to Warren Postma who suggested it in his comment at [WayBack] 18 Useful Commands to Get Hardware Information on Linux – Linuxslaves.
Note that on OS X you get this warning after brew install htop :
htop requires root privileges to correctly display all running processes,
so you will need to run `sudo htop`.
You should be certain that you trust any software you grant root privileges.
On Linux you don’t get this message as there you have the /proc file system providing enough information as explained at [WayBack] osx – Why does htop on Mac OS X require root privileges to see data for all processes, but on Linux it runs without root – Super User.
A workaround (involving the setuid bit) is at [WayBack] Running htop on Mac OS X needs root. Why?! | Blog | JoeNyland.me or by running visudo ensuring you don’t need a password for it at [WayBack] osx – htop isn’t returning CPU or memory usage!? – Super User

301 & 302 Redirect Generator Tool
Posted by jpluimers on 2017/12/19
[WayBack] 301 & 302 Redirect Generator Tool is a simple and cool tool:
Generate code to permanently or temporarily redirect your old URL to a new URL using htaccess, PHP, HTML, JavaScript, ASP or ASP.Net
Although using .htaccess files requires Apache to allow AllowOverride All which you might not want to, so here are a few other options and links you might want to check out:
- [WayBack] Apache Web Server Configuration for Web Site Redirect
- [WayBack] apache – Syntax for 301 redirect of www to non-www using httpd.conf – Stack Overflow

Some notes on having static-web site owners upload their content over SFTP
Posted by jpluimers on 2017/12/14
Yes, there are still static web-sites. A long time ago, they were uploaded over FTP. Now many use more secure protocols.
So here are some links and notes to allow this on a Linux based host running OpenSSH.
- [WayBack] SDB:SFTP server with Chroot – openSUSE
- [WayBack] OpenSSH/Server – Wikibooks, open books for an open world – The SFTP Server Subsystem
- [WayBack] OpenSSH/Cookbook/File Transfer with SFTP – Wikibooks, open books for an open world
- [WayBack] ssh – OpenSSH: Difference between internal-sftp and sftp-server – Server Fault
- [WayBack] How can I chroot sftp-only SSH users into their homes? – Ask Ubuntu
- “internal-sftp”
I got to the above via these two links:
- [WayBack] Allowing SFTP user to specific root directory only – Unix & Linux Stack Exchange
- [WayBack] [SOLVED] setting default folder location upon SFTP login
An alternative might be web-dave, but that would probably mean some hassle to separate uploading the site from accessing the site.

Interactive map of Linux kernel
Posted by jpluimers on 2017/12/05
The [WayBack] Interactive map of Linux kernel is way better than the static versions below that I got via
[WayBack] Interactive map of the Linux kernel subsystems. A little bit beyond what is required to use Linux. But great for those who want a deeper understanding of the kernel. – Joe C. Hecht – Google+
