APM for Kubernetes: Monitor Distributed Applications at Scale

Sep 10, 2025 By Anjali Udasi In Last9
When a payment service runs across 12 pods — each serving different customer segments — and an authentication layer spans three namespaces, performance issues can originate in both the application code and the orchestration layer. The challenge is linking request-level performance data with what’s happening inside the cluster: container CPU limits, pod scheduling decisions, and node-level events.

The End of "Good Code"? AI, Throughput, and Reliability with CircleCI CTO Rob Zuber

Sep 10, 2025 By Rootly In Rootly
Is “good code” still the right measure of engineering success in an AI-driven world? In this episode of *Humans of Reliability*, Rob Zuber, CircleCI CTO, joins Sylvain to explore how coding assistants are reshaping developer workflows and changing what teams value. Rob shares what he’s seeing across CircleCI’s customer base: a clear boost in throughput, new bottlenecks shifting from code creation to code review, and the rise of “vibe coding,” where engineers trust AI-generated code they may not fully understand.

The Answer to SRE Agent Failures: Context Engineering

Sep 9, 2025 By Mezmo In Mezmo
AI agents for SREs were supposed to slash mean time to resolution and eliminate alert fatigue. Instead, most teams got expensive, unreliable tools that burn through tokens without delivering insights. But what if the problem isn't the AI models themselves? Recent benchmarking reveals the real bottleneck: context engineering. When we tested our context engineering approach against conventional methods, the results were dramatic: Scroll down for our benchmark results to see the full comparison.

Kubernetes Monitoring Metrics That Improve Cluster Reliability

Sep 5, 2025 By Anjali Udasi In Last9
A Kubernetes cluster can generate more than 1,400 metrics out of the box. That’s a lot of numbers to sift through, especially when you’re troubleshooting a production slowdown in the middle of the night. The key is knowing which metrics tell you the most, with the least noise. These are the signals worth paying attention to when you need answers fast.

What is APM Tracing?

Sep 3, 2025 By Faiz Shaikh In Last9
APM tracing records the complete execution path of a request as it travels through your system, including database queries, external API calls, cache lookups, message queue events, and inter-service requests. Each step is captured with precise start and end timestamps, duration, and context such as service name, operation name, and relevant attributes. This lets you pinpoint where latency or errors originate without piecing together metrics and logs manually.

A Single Hub for Telemetry: OpenTelemetry Gateway

Sep 1, 2025 By Anjali Udasi In Last9
The OpenTelemetry Gateway (OTel Gateway) is a centralized service that collects, processes, and routes telemetry data—metrics, traces, and logs—across your infrastructure. In a typical setup, each service pushes telemetry directly to an observability backend. While this approach works well for small environments, it becomes increasingly difficult to manage as systems grow.
