🟣 #VictoriaMetrics will say present as OPEN SOURCE OBSERVABILITY DAY 2025 - October 23-24: one of our co-founders, Roman Khavronenko will present “Aggregating Metrics In-Flight: Challenges and Opportunities”. One of the common practices for improving the query speed in #Prometheus is to create recording rules for commonly used queries.

PromCon 2025 kicks off tomorrow, the biggest conference for #Prometheus fans! 🎉

Come visit us at the #Google Offices in Munich, Germany 🇩🇪 on October 21–22, 2025. We're excited to catch up with the community, share our latest innovations, and chat all about #OpenSource #monitoring and observability.

Looking forward to seeing you there!🎉

Does anyone use process_exporter (either stand alone, or via #Grafana #Alloy)?

If so are you monitoring all processes or specific? At work they want to monitor all processes on every server but this is making a cardinality nightmare.

#prometheus #devops #monitoring

Switching to #VictoriaMetrics transformed their approach:
✨ 80% less memory than #Prometheus
✨ Handles 76M+ active time series effortlessly
✨ Ingests 450K+ data points/sec in production
✨ Boosts visibility & customer experience

#Observability #TimeSeries #CaseStudy

This talk explores how #VictoriaMetrics builds on #Prometheus fundamentals to offer a more scalable and efficient alternative for teams managing high-ingestion workloads and demanding retention needs, without abandoning the familiar Prometheus ecosystem.

Nice to have everything #Ansible'd and monitored. I forgot that while downgrading to PHP 8.2 I had to uproot my #RoundCube install. One `./run.sh` in my Ansible repo and everything was back.

Also, thanks to #Prometheus, its node exporter, its ability to pick up text files left by scripts, plus #Grafana, I got notification that while the upgrade was happening (I had to remove all PHP 8.2 by hand, and wait till the automation installed the 8.4), one of the cron jobs (#NExtCloud's) was failing.

But at least,

it didn't ask me for diner...

Je suis en train de monter mon #homelab mais la question qui me tourmente, c'est la supervision.
#cacti ? #librenms ? #prometheus ?
Autre ?
Je cherche quelque chose de simple qui me permettent d'ajouter une machine et d'alerter sur des seuils d'alerte.
J'ai commence avec #prometheus, qui me semble tres bien, mais j'ai pas envie de passer du temps sur grafana pour creer un dashboard.
Des propositions ?

Septième jour de mon #randomctober
Avec une image de Saturne, par la sonde Cassini. Alors ça aussi, ça remonte pas mal en arrière. Car je travaillais sur les images de Mars à cette époque là aussi, et surtout, mais aussi sur celles de la sonde Cassini.

Ici, c'est le satellite "berger" nommé Prometheus que l'on voit, au sein d'une des dernières division des anneaux de Saturne.

Vue fortement zoomée sur une section de Saturne où le bord des anneaux est presque vu d'au dessus, avec ses innombrables sillons clairs et sombres. On voit une toute petite bille irrégulière entre les anneaux et un petit anneau à droite. La planète est visible en arrière plan et occupe presque tout le cliché, avec un bord doux, du fait de son atmosphère.

One of the common practices for improving the query speed in Prometheus is to create recording rules for commonly used queries. While this usually works great, recording rules have a cost: The raw metrics still need to be stored in the #Prometheus, even if we don't need them.

Scaling quality in #Uyuni with #TestOps: using #Terraform & #Salt for repeatable test environments, #Prometheus & #Grafana for visibility, smart test selection in PRs. Check out this #oSC25 video. #openSUSE https://youtu.be/zDV_B4qN0z8?si=0zH4dI6FxMMjIxvA

Anybody know if there's a user friendly interface for displaying #Prometheus metrics? I use #Anubis to protect a site and it binds "metrics" to a certain port. I was able to figure out that I can curl the plain text with:

curl 127.0.0.1:9090/metrics

But it basically just spits the raw text out. That's fine and informative, but I can't seem to find any documentation on the Anubis site about any other available endpoints or options, user friendly ways to access it, etc. I just guessed at it.

reaction prometheus metrics exporter just reached v1.0.0!
Consider using it if you love metrics and want some for reaction.

#TechEvents #Observability #Prometheus

Prometheus has become the go-to standard for metrics-based #monitoring, but as environments grow in complexity and scale, teams often find themselves hitting its operational limits, especially around cardinality and long-term storage.This talk explores how #VictoriaMetrics builds on Prometheus fundamentals to offer a more scalable and efficient alternative for teams managing high-ingestion workloads and demanding retention needs, without abandoning the familiar #Prometheus ecosystem.

Bonjour, Paris! 🇫🇷
Join us for an exciting #VictoriaMetrics #Meetup in the City of Lights, hosted by Criteo!
📍 Location: Criteo HQ, #Paris.
🗓 October 15th
🕡 18:00
🎙 Diana Todea - VictoriaMetrics Developer Advocate will present, “Beyond #Prometheus: pushing the boundaries of scalable #monitoring with VictoriaMetrics”.

Tired of fighting with SNMP and confusing network data? 😤
Join our "Nonsense Networking" live stream where we make sense of network #metrics, #logs, and #flows. We'll cover the common pain points and show you better alternatives.
