Pod Scheduling Delay Detection
Identifies deployments experiencing scheduling delays and analyzes root causes before they become bottlenecks.
Overview
Pod Scheduling Delay Detection monitors pod creation requests and identifies when pods are delayed in the Pending state due to insufficient resources, node selectors, affinity rules, or other scheduling constraints.
Wave analyzes the root cause of scheduling delays—whether it's CPU/memory constraints, PV availability, node availability, or constraint misconfigurations—and provides specific recommendations to resolve bottlenecks before they impact scaling operations.
Why Better Than Manual Troubleshooting
| Manual Troubleshooting | Wave Delay Detection | |
|---|---|---|
| Detection Speed | Notice delays only when users report slow scaling or check kubectl manually | Real-time detection of scheduling delays with immediate alerts |
| Root Cause Analysis | Manual kubectl describe and event log analysis required | Automatic root cause identification with specific remediation steps |
| Bottleneck Prevention | Reactive—fix issues after they impact application performance | Proactive—identify and resolve constraints before scaling failures |
Key Outcomes & Benefits
Identify scheduling delays within seconds of occurrence
Reduce mean time to resolution with automated root cause analysis
Prevent scaling failures caused by scheduling constraints
How It Works
1. Scheduling Monitoring
Tracks all pod creation requests and measures time spent in Pending state before scheduling.
2. Delay Detection
Identifies pods with abnormal scheduling delays (> threshold) and captures scheduling events.
3. Root Cause Analysis
Analyzes scheduler events to identify cause: resource shortage, node constraints, PV issues, etc.
4. Remediation Guidance
Provides specific recommendations: add nodes, adjust requests, modify constraints, or expand storage.
