An overlooked aspect of monitoring is understanding the baseline and theoretical ceiling of your architecture. Here’s a great example for testing the throughput of your Kubernetes ingress controller using some open source tools.
If you enjoy TCP network monitoring and performance debugging conversations, you’re going to love this one. Props to Cloudflare for sharing their lessons learned in performance tuning the Linux kernel.
An excellent example for capturing network flow telemetry within your Kubernetes cluster using eBPF. You may not need this, but it’s a very approachable tutorial that should be helpful elsewhere.
I love this post from Slack engineers on their continuous load testing platform and how it’s elevated their resilience by helping to identify performance regressions before they make it to production.
If you already administer Kubernetes clusters, chances are you’re familiar with CrashLoopBackOff. On the other hand, if you’re a developer using K8s… maybe not so much. This post is a good overview of the concept along with some examples for debugging and monitoring this state in your Pods.
A visual explanation of some of the attributes and constraints that affect how we store and query time-series data.
Chronosphere is the only observability platform that puts you back in control by taming rampant data growth and cloud-native complexity, delivering increased business confidence. See how companies like Abnormal Security cut observability costs and boosted platform reliability with Chronosphere’s end-to-end solution. Read the story here. (SPONSORED)
A handy guide for configuring Grafana to use a shared remote database for highly available setups.
This author makes a strong case for adopting OpenTelemetry for modern systems and applications. Probably a good resource to share with your friends who are still relatively new to the space.
I’ve read so many articles like this, but it’s always interesting to read others’ take on what distinguishes these two capabilities.
A look at the newest release for Grafana Tempo with a look forward at their plans for the new Parquet backend and TraceQL query language planned for Tempo 2.0.
“Locust is an easy to use, scriptable and scalable performance testing tool.”
“Zero instrumentation observability on Kubernetes with eBPF”
See you next week!
