Log Monitoring
How to Monitor Logs in Production
This post covers four operational gaps that make log monitoring hard in production: fragmented log querying across services, missing correlation between logs and traces, the inability to see logs in the context of your broader APM signals, and the failure to detect recurring error patterns before they escalate. We walk through each gap and show how treating logs as a first-class part of your investigation workflow: queryable, correlated, and continuously monitored, changes how fast you get to root cause.

Monitoring Kafka at Scale with OpenTelemetry
In this post, we'll walk through what production-grade Kafka observability actually looks like: which metrics matter and why, where traditional monitoring falls short, and how an OpenTelemetry-native approach gives you the correlation and visibility you need to catch these problems before they become incidents.

Monitoring RED Metrics in Production
RED metrics — Rate, Errors, and Duration — give you direct visibility into what your users are actually experiencing, something infrastructure metrics like CPU and memory can't tell you on their own. This post covers what each signal means, how to interpret changes in rate, error rate, and percentile-based latency, how to collect RED metrics using OpenTelemetry's spanmetrics connector, how to use them as the foundation for SLO monitoring, and how to turn that visibility into active alerting so you know about problems before your users do.

How to Monitor and Control GenAI Costs in Production
In this post, we’ll look at what production-grade GenAI cost visibility actually looks like in practice. We’ll walk through the most common operational gaps teams run into and show how those gaps can be closed by treating cost as a first-class runtime signal, making it traceable, attributable, and actionable before the next spike shows up on a bill.

How to Make GenAI Costs Observable in Production
In this blog, we’ll walk through a set of practical strategies teams use in production to regain control over GenAI spend by treating cost as an operational signal, designing the right telemetry, and closing the feedback loop between engineering and finance before the next spike shows up on a bill.

3 Challenges When Implementing Logging & How To Overcome Them
Logging is often seen as a simple building block — but done poorly, it becomes expensive noise that slows incident response and inflates infrastructure costs. This guide explores three critical logging challenges that plague development teams: excessive low-value logs, missing contextual identifiers, and fragmented monitoring views, plus actionable solutions to optimize your logging strategy.

RED Metrics: A Better Way to Understand What Your Users Are Experiencing
When monitoring applications, most teams start with CPU and memory. These are easy to collect and visualize. But while they help you understand system resource usage, they often fail to tell you what really matters: 👉 What is the user experiencing? In this post, I’ll walk you through a better way to monitor services using RED metrics, and how they can help you move from system-centric to user-centric observability.

Right Sizing
Rightsizing workloads using Vertical Pod Autoscaler (VPA)
The Vertical Pod Autoscaler (VPA) automatically adjusts CPU and memory resources for Kubernetes pods based on actual usage, optimizing performance and efficiency. Unlike the Horizontal Pod Autoscaler (HPA), VPA focuses on fine-tuning resource requests and limits. By leveraging the VPA Recommender, Updater, and Admission Controller, you can avoid over-provisioning and under-provisioning, leading to cost savings and improved application performance.
