Data visualization with Grafana and Telegraf - Zoltán's Blog
Few weeks ago we have decided to create a dashboard where we can monitor the status of the SUSE Linux Enterprise maintenance update queue. Naturally there are tons of cool open source solutions to build this type of monitoring. Two decades ago I probably would have written a Perl or Python based monitoring script for the monitoring part and use the good old gnuplot (http://www.gnuplot.info/) to visualize the data and create an active page written in some silly web UI framework. Let’s just say that luckily those times has passed.
I have turned to the development team of the openQA and asked them what do they use for their monitoring system. It is a really good open source practice to use the technology what our friends are using so we can ask for help and we can later contribute to their projects.

Apply Linux Kernel Patches from LKML | Adam Young’s Web Log
Linux kernel work can call for you to test out a patch set that someone has posted to the Linux Kernel Mailing List (LKML). If the patch sets are sufficiently long enough, you want to apply them all together, and not have to down load them individually. I recently worked through this, and here’s how I got things to work.
For example, picking the top one (today) from LKML: [PATCH 0/8] MediaTek watchdog: Convert mtk-wdt.txt to dt-schema. I actually don’t care about this particular patch, but the process is the same.There is a link to this on the lore.kernel.org Webpage.
Note that this title bar implies there are 8 patches (labeled 1 to 8) inside it, and a Patch labeled 0 which serves as the header to the whole patch set. When you try to apply the patch using git -am it is going to complain about that first one, but this is not a problem.
If, like me, you tend to do development work on a system that is not your primary email client, you will want a way to download the patches directly to the target machine. I am going to use wget to fetch a patchset in its mailbox format using gzip compression. There is a link to the gz file at the bottom of the page. Scroll to the section that shows the thread.
