📄️ Disk Pressure in Kubernetes Nodes
Kubernetes nodes operate with finite disk space, which is essential for storing logs, temporary files, and other system data. When this space becomes critically low, the node enters a Disk Pressure condition, potentially affecting its performance and the stability of the entire cluster.
📄️ Insufficient Memory in Kubernetes Nodes
Kubernetes nodes require adequate memory to ensure the smooth execution of workloads and system processes. When a node experiences Insufficient Memory, it may enter a critical state, leading to degraded performance or even workload eviction.
📄️ Insufficient PID in Kubernetes Nodes
Kubernetes nodes rely on process IDs (PIDs) to manage and execute workloads. When a node runs out of available PIDs, it enters an Insufficient PID condition, preventing new processes from being created. This can disrupt workloads and compromise the stability of the cluster.
📄️ PVC Usage Exceeds Threshold
Persistent Volume Claims (PVCs) provide storage resources for Kubernetes workloads. Efficient storage utilization is critical to maintaining system performance and avoiding disruptions.
📄️ Node Storage Usage Exceeds Threshold
Kubernetes nodes require sufficient storage availability to ensure smooth operation of system processes and workloads. When storage availability on a node falls below a defined percentage (default: 20%) of its total capacity, it can lead to degraded performance or system failures.
