There are no queries against storage, no new query language to learn, and nothing tied to a specific vendor, so any Prometheus-compatible setup can use it.

📌 Save your seat and come say hi in #Munich. See you at #PromCon! 🎉

The article examines common issues, including metric loss between scrapes, cardinality explosion caused by unique pod labels, and inaccurate dashboards when using traditional #Prometheus and Pushgateway approaches.

안녕, 서울! 🇰🇷
Will be present at #KCD Korea.
Join Zhu Jiekun, Software Engineer at #VictoriaMetrics, for the session:
🎤 Metrics War: #Prometheus vs. #OpenTelemetry? Your Tax for "Vendor-Agnostic"
If you're using Prometheus, from SDK instrumentation and Prometheus Agent to long-term storage like #Thanos, would you migrate to OpenTelemetry for vendor-agnostic #observability? If you were starting from scratch today, which would you choose?

Does anyone use Prometheus webhook notifications with XMPP, specifically Prosody? There seem to be several ways of doing it but I'm struggling to get any of them to work. Any help would be welcome. TIA #prometheus #xmpp #webhook #prosodyim

🚀 Running 100M+ active series is no small feat.
From #Prometheus to #VictoriaMetrics: how it measures up against# Mimir. Trade Republic runs 100M+ active series across several clusters. This short talk walks through why we moved off Prometheus, the topology we landed on, and a side-by-side #benchmark comparing Mimir and VictoriaMetrics across ingestion, query latency, CPU/RAM/network, and the operational reality of running each.

Starting from a single validation policy, we show how policy evaluations and enforcement results are exposed as metrics, ingested into VictoriaMetrics, and queried through a standard #Prometheus-compatible API. A minimal dashboard is then used to inspect policy failures, affected namespaces, and policy execution duration.

Heads up for those running #Prometheus on #Debian unstable or testing:

prometheus (3.5.3+ds1-1) urgency=medium

The Prometheus Web UI has been completely disabled in this package. Upstream removed the Classic UI in v2.34.0. The newer React and Mantine UIs cannot be shipped because they require complex, pre-compiled toolchains (node-vite and rust-rolldown) that are not yet packaged in Debian and cannot be built offline.

Install `apt-listchanges` and update manually.

Is there anything decent for #Prometheus and #PHP monitoring? All the PHP exporters look to have been abandoned 4 or more years ago. There also seems to be a lack of decent data from #nginx exporters. I guess for PHP, I'd need to use some kind of OpenTelemetry stuff? For nginx it might have to be feeding access logs into something?

🥳 New update - Real-time Cardinality Estimations for #VictoriaMetrics and #Prometheus
#Cardinality problems usually begin with a small, seemingly harmless change: you add a label, and suddenly one metric becomes thousands of unique series.

New post: Monitoring our FreeBSD Mastodon instance.

burningboard.net runs as a stack of Bastille jails on FreeBSD, so I watch it from a separate box with Prometheus, Grafana and Loki. The interesting part is the FreeBSD-shaped gaps: no native ZFS metrics, nothing for the Mastodon API or our S3 media bucket. A small textfile collector fills all of it.

This is how I keep an eye on the very instance I'm writing this on:

May was awesome for the VictoriaMetrics #Observability Stack 🚀
We’ve introduced a range of updates and new features across VictoriaMetrics.
📊 Native #Prometheus histograms support: native histogram ingestion is now supported across vmagent, vmsingle, and cluster.
🛡️ More reliable vmagent shutdown: draining in-memory queues before fallback, reducing alerting gaps.
🔄 Smarter rerouting: improved vminsert handling to avoid rerouting storms and stabilize ingestion.
