Kubernetes Resource Usage Monitoring: Best Practices, Metrics & CubeAPM Guide
Kubernetes has become the default choice for orchestrating containers, with Gartner estimating that by 2027, over 90% of global enterprises will run containerized applications in production. Its strength lies in abstracting compute, networking, and storage while enabling autoscaling and resilience at scale. But with this flexibility comes risk: resource mismanagement leads to CPU throttling, memory […]

eBPF Kubernetes Monitoring: Deep Visibility, Zero Overhead, and Cost-Efficiency with CubeAPM
Kubernetes adoption is exploding—over 66%+ of organizations now run it in production, but monitoring hasn’t kept up. Teams juggle thousands of short-lived pods, noisy microservices, and hybrid nodes, yet still struggle to get real-time visibility. Without eBPF, monitoring depends on sidecars, agents, or log shippers that bloat CPU/memory usage, miss kernel-level signals, and drive data […]

Kubernetes Exit Code 137 (Out of Memory) Error: Container Lifecycle, Resource Limits, and Restart Loops
Exit Code 137 in Kubernetes means a container was killed by the Linux Out-of-Memory (OOM) process after exceeding its memory limit. These failures cause pods to restart abruptly and can ripple into wider outages. In the Sysdig 2023 Cloud-Native Report, 49% of containers were found running without memory limits, making OOM events a common reliability […]

Top 8 Windows Server Monitoring Tools: Features, Pricing, and Best Use Cases
Windows Server monitoring tools are indispensable for safeguarding performance, uptime, and security in increasingly complex IT environments. As of 2025, the global observability tools and platforms market is estimated to exceed US$28.17 billion, reflecting how vital monitoring has become across enterprise stacks. But picking the right Windows Server monitoring tool remains a headache. Costs balloon […]

Kubernetes OOMKilled Error: Deep Dive into Memory Leaks, Limits, and Kernel Signals
Kubernetes OOMKilled error occurs when a container exceeds its memory limit and is terminated by the kernel’s Out-Of-Memory (OOM) killer. In practice, such failures contribute to the wider reliability challenges in Kubernetes: a recent survey found that 87% of organizations experienced outages in the last year, and 83% said those were Kubernetes-related. For businesses running […]

Monitoring Nginx Error Logs: Real-World Examples & CubeAPM Walkthrough
Nginx sits at the core of today’s internet, handling millions of requests per second for APIs, streaming platforms, and e-commerce sites. When it fails, it often fails loudly—502 Bad Gateway responses, upstream timeouts, SSL errors, or worker crashes—all captured inside its error logs. These logs act as a forensic trail, pinpointing whether issues stem from […]

Monitoring Nginx for Performance & Reliability: A Complete 2025 Guide with CubeAPM
Monitoring Nginx is critical because it powers 33.3% of all websites currently. With its role as a web server, reverse proxy, and load balancer, even small issues in latency or error rates can disrupt user experience and revenue. Many teams face challenges with Nginx monitoring: hidden 5xx errors, overwhelming log volumes without smart sampling, and […]

Monitoring Helm Deployments in Kubernetes: Cost-Efficient Observability with CubeAPM
Monitoring Helm Deployments ensures visibility into installs, upgrades, rollbacks, and failures across Kubernetes clusters. With GitOps and microservices adoption surging, observability is critical. Nearly 80% of production outages stem from system changes. For many teams, monitoring Helm Deployments is painful. A helm upgrade may succeed, yet pods crash, hooks fail, or dependencies misalign. These hidden […]

Kubernetes Pod Unknown State : 3 Common Causes, Fixes & Monitoring with CubeAPM
Kubernetes pod “Unknown” state occurs when Kubernetes cannot determine the Pod’s condition, usually because of lost node communication, API server issues, or cluster state mismatches. Recent studies found that over 50% of cluster-wide failures stem from errors in cluster-state dependencies, making issues like “Unknown” pods a common operational risk. For businesses, these failures can cause […]
