Kubernetes Pod Resource Quota Exceeded Error: Namespace Limits, CPU Throttling & Workload Blocking
The “Kubernetes Pod Resource Quota Exceeded” error occurs when a namespace or workload requests more CPU, memory, or storage than allowed by its configured limits. It’s a common operational challenge in large clusters where strict quotas control resource usage. Such violations can block new Pod deployments, slow workloads, or even halt CI/CD rollouts. CubeAPM, an […]
Kubernetes PID Pressure Error Explained: Node Evictions, PID Limits & Process ID Exhaustion
The Kubernetes PID Pressure error occurs when a node runs out of available process IDs (PIDs), preventing new containers from starting and causing workload disruptions. This state often triggers pod evictions, frequent restarts, and degraded cluster performance, especially in high-density or microservice-heavy deployments. CubeAPM provides deep visibility into Kubernetes PID pressure error by correlating kernel-level […]
Kubernetes Disk Pressure Error Explained: Node Evictions, Root Causes, and Monitoring with CubeAPM
Kubernetes disk pressure error occurs when a node runs critically low on disk space or inodes, prompting the kubelet to evict pods or halt new scheduling. In fact, 93% of organizations now run Kubernetes in production, making disk and resource management a critical reliability concern. When nodes hit DiskPressure, workloads are rescheduled, deployments fail, and […]
Cassandra Monitoring: Metrics, Troubleshooting, and Observability with CubeAPM
With over 35% of Cassandra workloads now running in the cloud, ensuring consistent performance across distributed nodes is a growing challenge. Many teams struggle with fragmented monitoring tools, costly data pipelines, and poor correlation between metrics and logs. CubeAPM is the best solution for Cassandra monitoring, offering unified observability across metrics, logs, and error tracing […]
Redis Monitoring: Key Metrics, Alerts, and Observability with CubeAPM
Redis monitoring ensures your databases run efficiently and reliably. Although Redis powers over 70% of real-time caching systems worldwide. Yet, as systems scale, teams face issues like memory fragmentation, latency spikes, hidden key evictions, and replication lag that degrade performance and are difficult to detect without full visibility. CubeAPM is the best Redis monitoring solution. […]
8 Best Flask Monitoring Tools in 2025 for Real-Time Python App Observability
Flask monitoring tools have become essential as Python powers modern APIs and microservices. The global observability market is expected to reach $28.17 billion by 2035, up from $19.8 billion. Yet, teams still struggle with unpredictable APM bills, limited data retention, and complex agent setups, so teams seek simpler, more transparent Flask monitoring solutions. CubeAPM is […]
Kubernetes Exit Code 139 Error (Segfault): Debugging Pod Restarts and Deployment Failures
Kubernetes Exit Code 139 error (Segmentation Fault) occurs when a container process attempts to access restricted memory, forcing the operating system to kill it. These runtime crashes don’t just restart containers — they ripple through clusters, stalling deployments, disrupting microservices, and delaying rollouts. The business impact is massive, unplanned IT downtime now costs an average […]
Best Laravel Monitoring Tools in 2025: Top APM Solutions for PHP, Queues, and Database Performance
Laravel is one of the most popular PHP frameworks for modern web apps, known for its clean syntax and rich ecosystem. But as applications scale, maintaining visibility across Eloquent queries, Horizon queues, and Blade rendering becomes harder. Performance issues like slow requests or hidden N+1 queries often go unnoticed until they affect users. CubeAPM simplifies […]
Top Spring Boot APM Tools in 2025: JVM Performance, OpenTelemetry Tracing & Cloud-Native Observability
Spring Boot powers over 46% of modern Java microservices according to JetBrains’ 2024 Developer Ecosystem Survey — yet monitoring them remains a constant challenge. As systems scale, developers face slow queries, thread pool exhaustion, and tracing gaps across asynchronous controllers and reactive pipelines. CubeAPM simplifies Spring Boot monitoring with native OpenTelemetry auto-instrumentation, context propagation for […]
