These are some of the blog articles I have published during the years.
Many of the old articles still have a lot of valid and current information even though they were written years ago.
In this article I am going to explain how I got control of my UPS (Uninterruptible Power Supply) installation using NUT via PFSense+ so I can monitor and manage the UPS from the main router in my HomeLab. In addition I will show how I have configured Zabbix with a new NUT template for monitoring, alarm generation and long term metrics for my UPS.
Will OpenAI/Whisper recognized my “Andalusian accent” when I speak Spanish and transcribe the audio to text without problems? I had to use 0.032759 kWh of energi to find this out.
Not long ago I got some nice second-hand SAS drives that I could use with my home server. I didn’t have a SAS controller that I could use with these drives at that time, so I started looking for one. I didn’t want to spend too much money and the specifications I wanted were not very advanced.
After some investigation I decided to purchase a Broadcom MegaRaid SAS 9341-8i controller. This controller is a bit old but it had the functionality I was looking for at an affordable price.
After several weeks of intense testing, fixing configuration problems, re-indexing data and experiencing problems when upgrading our Kibana indices, we managed to upgrade our 36 Kibana instances and our Elasticsearch cluster in production from version 5.6.16 to 6.7.1 a couple of weeks ago.
I am writing this article with contradictory feelings, Am I having a bad day on top of The Oracle at Google not giving me answers, or is the documentation of the Keepalived software totally outdated and old?
If you have to administrate an Elasticsearch cluster, there are some common maintenance tasks that you will have to run to keep your data growth under control, backup your indexes and keep the cluster updated.
“CEREBRO” is an Elasticsearch web admin tool built using Scala, Play Framework, AngularJS and Bootstrap. It is equivalent to KOPF with some extra new features.
We started using Zabbix to monitor the IT infrastructure at The University of Oslo in 2014. During all this time we have been running all our Zabbix servers on VMware virtual servers with an acceptable level of performance. This situation changed some months ago when the VMvare+Storage we were using did not have more available resources for us to grow and it was slowing down the future development of our monitoring system.
