Observability & Monitoring Community Slack
Come hang out with all your fellow Monitoring Weekly readers. I mean, I’m also there, but I’m sure everyone else is way cooler.
From The Community
Towards Jaeger v2 💥💥💥 Moar OpenTelemetry!
An exciting update on the next major version of Jaegar. Great to see stronger alignment with OpenTelemetry (native OTLP support, OTel collector extensions!), even if it means some short-term pains, e.g. CLI configuration compatibility.
A different perspective on the CrowdStrike outage that affected everyone, how it can be avoided once eBPF is production-ready for Windows, and what you can do in the meantime.
Promruval v3: Validation of Loki rules and more
A look at the latest release of Promruval, and open source tool for validating Prometheus rules and expressions. Nifty tool with a good understanding of how folks use (and misuse) Prometheus.
Why Care About Exception Profiling in PHP?
I don’t use PHP, but I love reading about profilers and what we can learn from them. Coming from a very exception-happy Ruby background, I was surprised to hear how expensive they are in PHP-land.
Can eBPF Detect Redis Message Patterns Before They Become Problems?
How Anteon designed their Redis observability agent using eBPF. Some useful learnings for anyone curious about setting up your own custom eBPF hooks.
Tips and considerations for anyone dealing with the traditional “who watches the watchers” conundrum.
Axiom is your hedge against observability and security tools: ingest, store, and query 100% of your event data in Axiom and then flow exactly what you need to vendors. Use Axiom for cost-reduction, silo-busting, tool consolidation, and vendor experimentation - all without compromising a single byte of data. (SPONSORED)
Unveiling the black box with observability stack
How GovTech Singapore engineers use a fully open source stack to gain observability on their applications and infrastructure.
Scaling Prometheus with Thanos
A solid overview of Thanos and its components, but the installation guide is underwhelming imho. Thanos is one of those projects that makes it possible to scale Prometheus, but you don’t truly understand its inner workings until you’ve used it in anger.
