2020 Week 8

Build a power cable for my graphics card

As I wrote last week, I want to add a graphics card to my "Testing" server that I can also use it for gaming. The problem is that the power supply only has two 6 Pin PCI connectors and the graphics card I bought has one 8 Pin PCI connector. One 8 Pin connector can handle 150 watts and one 6 Pin connector can handle 75 watts. So two 6 Pin connectors can deliver the same power as one 8 Pin connector. I found a cable that actually does that but had two mini 6 Pin connectors 😭 After many hours of searching for a cable that I need, I bought only the 6 Pin connectors and replaced the mini 6 Pin ones. That was super easy and I am super happy that I can finally play some games.

Migrating my Prometheus monitoring server to another server

I wanted to do that for a very long time but I never found the right way to do it until I found out that Prometheus has a feature that is called "remote_read". With that feature, it is possible that one Prometheus instance read from another. So I set up the new one and the old one will run until all its data got deleted. I only store the data for 60 days because I don´t need it longer. So in 60 days I can stop the old one and remove everything.

Power loss at home

Because of our toaster, we had a power loss at home and the MySQL database on one of my servers at home crashed 😭After some hours I, fortunately, recovered all of the data and got MySQL starting again.

Because of that, I am now searching for a UPS to prevent it from happening again. I searched for many hours but it not that easy to find the right one. I will update you if I find one.

Docker blog post

I'm working on a blog post about Docker and why I´m using it. I think that it should be finished in the next days. So if you are interested in Docker you can check my blog in the next days.

The things I write on this blog are my own opinions and based on the things I learned running my own infrastructure or building my personal projects. It stands in no connection with my job.
