The #Aquara temperature sensor on my balkony is flaky. Every couple of weeks it just disappears for no apparent reason. So I spent my morning figuring out how to enable #Prometheus metrics in #HomeAssistant and wrote an alerting rule to get a notification on my phone via my local ntfy instance.
Yay, computers. 
Still have to implement the #HomeAssistant #prometheus/#OTEL export to make #Keda be able to do this.
Plus, I still need to get a decent autoscaler in place. But first, to blog about my current one. Main "issue" is that my current one only takes one node offline every cron job run. So to take 5 dow,n it needs 50 minutes.
That is not ideal when it gets hotter than desired, but doable when it's mainly idle nodes. This plays in directly with https://blog.wyrihaximus.net/2024/12/building-a-kubernetes-homelab-with-raspberry-pies-and-lego-nodes-enclosure/
#OpenTelemetry resource attributes and #Prometheus.
You know it and we know it: they don't always play well together.
This year, #LFX mentee Victoria Nduka researched how Prometheus handles #OTel resource attributes and how we can improve the user experience. Read our latest blog post to learn about her research findings and insightful recommendations. https://opentelemetry.io/blog/2025/ux-research-prometheus-otel/
"We’re writing to remind you that as of October 22, 2024, Monitoring Query Language (MQL) is no longer a recommended query language for Cloud Monitoring. We made this change to focus on PromQL, the open-source standard for time series querying, which offers similar functionality, a wider user base, and more community resources."
Scaling Pingcap #TiDB #observability from #Prometheus to #VictoriaMetrics has been a game-changer! Thanks to the PingCAP team for sharing their experience!
50% lower CPU usage 35% less memory, eliminating OOM crashes Query time reduced from 40 mins to 3 mins
PingCAP clients, like Pinterest, are thriving with a faster, more resilient monitoring stack! Curious about the switch? Read more

How to Install #Prometheus on #Debian #VPS Here's a guide detailing how to install Prometheus on Debian VPS:
What is Prometheus?
Prometheus is an open-source, systems monitoring and alerting toolkit designed to collect and analyze metrics from servers, applications, and services. Initially developed at SoundCloud, Prometheus is now a popular Cloud Native Computing Foundation (CNCF) project widely adopted ...

Man[1] kann #Telegraf direkt mit #Prometheus verbinden, und dann #Grafana auf die Daten in #Prometheus setzen. Dann kann man[1] #InfluxDB komplett abschalten und vom Server werfen, und dann hat man[1] eine Baustelle weniger, und das ist schön.
Wollte mir bei der Gelegenheit #Perses näher anschauen, aber konnte es nicht als Container hinter nginx mit Subpath betreiben 
Dann halt nicht.
[1] ich 
I use #Grafana as well, to create the dashboard itself.
The underlying data comes mostly from #Prometheus (which pulls data from any software that provides a compatible endpoint, which is a lot of stuff).
To monitor ping times to various servers (and also implicitly, that they are up), I use #collectd running on a couple of VMs.
Prometheus+collectd get me most of the system/server-level data I want on a dashboard.
Meta's Giant Step Toward Superintelligence
Meta is building huge data centres, each housing multiple multi-gigawatt clusters, to fuel its SuperIntelligence Labs. The first of these, named Prometheus, is expected to come online in 2026. A second larger project Hyperion is also in progress and may eventually be scaled up to 5 gigawatts.
Version 4.9.0 of #syslog_ng is now available. Among others it adds:
- #Prometheus exporter
- more efficient file/directory monitoring on #Linux
- #FreeBSD audit source
Read more at https://github.com/syslog-ng/syslog-ng/releases/tag/syslog-ng-4.9.0
Packages for #Debian / #Ubuntu / #openSUSE / #Fedora & #EPEL are available.
In case you didn't know, as I didn't as of yesterday, it is possible to get anonymized statistics from #SearXNG using their #prometheus endpoint. And yes, that also works if you scrap the data using #VMagent and store them into #VictoriaMetrics on #OpenBSD.
Still got to thing of a better way to display those because those lines are a bit messy.
How to Install and Configure Node Exporter on #Debian #VPS This article will provide a guide for how to install and configure Node Exporter on Debian VPS.
What is Node Exporter?
Node Exporter is a #Prometheus exporter that collects and exposes hardware and OS-level metrics from Linux and Unix-like systems. It runs as a background service and makes these metrics available ...

Modern #technoBureaucracy, heir to Promethean myth of endless growth, demands triple decolonization: 1) post-Marxist, of promises of the #technicalSystem (#Arendt, #Mignolo, #Escobar, #Mumford), 2) material and immaterial of #center/ #periphery relationships (#Amin, #Cusicanqui, #Ferdinand), 3) decolonization of nature itself, listening to #subaltern voices and other epistemologies (#Spivak, #Harding). Decolonization also means de-anthropocentrating the world, beyond #Prometheus.
Furthering the collapse? This is just mind boggling!
Zuckerberg pledges hundreds of billions for AI data centers in superintelligence push
“Its first multi-gigawatt data center, dubbed #Prometheus, is expected to come online in 2026, while another, called #Hyperion, will be able to scale up to 5 gigawatts over the coming years, #Zuckerberg said in a post on his #Threads social media platform.
"We're building multiple more titan clusters as well. Just one of these covers a significant part of the footprint of Manhattan," the #Billionaire CEO said.”
