Top APM Tools for Cloud-Native Apps in 2025: Kubernetes-Native Monitoring, OpenTelemetry, and Real-World Cost Benchmarks
Choosing the top APM tools for cloud-native apps has become critical as modern architectures rely on microservices, containers, and Kubernetes orchestration. Cloud-native environments scale fast — and fail fast — demanding observability platforms that can track distributed systems in real time. CubeAPM is built precisely for this reality. It delivers deep visibility into Kubernetes clusters, […]
Kubernetes Memory Limit Exceeded Error: Resource Limits, Node Pressure & Cluster Stability
The Kubernetes Memory Limit Exceeded error occurs when a container uses more memory than its Pod limit. The kubelet responds with an Out-Of-Memory (OOMKill), terminating and restarting the container. If ignored, this can stall Deployments, trigger CrashLoopBackOff cycles, and disrupt service availability. For production workloads, the impact is immediate—customer-facing apps can fail, jobs may stop […]
Kubernetes CPU Throttling Error: Node Scheduling, Pod QoS Classes, and Telemetry with CubeAPM
The 2024 State of Production Kubernetes report by Spectro Cloud found that over 71% of organizations hit performance bottlenecks tied to CPU limits and throttling. This issue occurs when Kubernetes enforces strict CPU quotas, causing workloads to stall even when nodes have idle capacity. For latency-sensitive services—APIs, trading systems, or SaaS apps—CPU throttling means higher […]
9 Best Next.js Monitoring Tools for High-Performance Web Applications
Next.js monitoring tools help teams track Core Web Vitals, detect API route bottlenecks, and ensure seamless SSR performance across distributed environments. However, choosing the right Next.js monitoring tool is difficult for teams due to rising data costs, limited correlation between logs and traces, and vendor-locked telemetry pipelines. CubeAPM is the best Next.js monitoring tool provider […]
Kubernetes kubectl Couldn’t Get Current Server API Group list Error: API Server, Kubeconfig, DNS & RBAC Monitoring with CubeAPM
Kubernetes now powers over 5.6 million developers worldwide according to the CNCF 2023 Annual Survey, making it the backbone of modern infrastructure. One common issue kubectl couldn’t get current server api group list error: couldn’t get current server API group list, which appears when the client fails to fetch API groups from the cluster due […]
MongoDB Monitoring for Modern Teams: End-to-End Observability with CubeAPM
MongoDB monitoring is the process of tracking performance metrics, logs, and traces to maintain database health and optimize query execution. Today, over 70% of Fortune 500 companies rely on MongoDB for mission-critical workloads. Effective monitoring reveals query latency, replication lag, cache usage, and system resource trends before they impact applications. Yet, monitoring MongoDB databases remains […]
MySQL Monitoring with CubeAPM: Key Metrics, Tools, and Best Practices
MySQL Monitoring is essential for ensuring database reliability, query efficiency, and application uptime. MySQL remains the second most popular database globally, powering millions of production systems across SaaS, fintech, and eCommerce platforms. With growing workloads and complex architectures, many teams still struggle with fragmented monitoring. Traditional tools make it hard to correlate MySQL metrics with […]
Monitoring Postgres Slow Queries: How to Detect and Fix with CubeAPM
Monitoring Postgres Slow Queries is now essential for modern applications where milliseconds define user experience. Over 40% of production slowdowns stem from inefficient queries. Without real-time monitoring, these bottlenecks cascade across APIs and user-facing services, crippling performance. Yet most teams struggle when monitoring Postgres slow queries, as logs are noisy, dashboards lack query-level context, and […]
PostgreSQL Monitoring with CubeAPM: Metrics, Setup & Real-World Insights
PostgreSQL monitoring is essential for ensuring performance, reliability, and scalability in modern data environments. Currently, PostgreSQL holds 16.85% of the global relational database market, known for handling production workloads. Effective PostgreSQL monitoring provides real-time visibility into queries, replication lag, and resource utilization, helping teams maintain uptime and optimize costs. But monitoring PostgreSQL at scale remains […]
