Kubernetes Debugging: Then vs Now vs Intelligent

🚨 Kubernetes Debugging: Then vs Now vs Intelligent
Debugging Kubernetes issues has evolved.
But has it evolved enough?
Let’s compare 👇

🔧 1️⃣ Manual (Traditional) Debugging
• kubectl describe pod
• kubectl logs -f
• Check events
• SSH into nodes
• Grep logs
• Reproduce issue
⏱ Time to RCA: 30 mins – hours
💥 Risk: Human error, tunnel vision
🧠 Depends heavily on individual expertise
📉 No correlation between logs, metrics, changes
You react after downtime.

📊 2️⃣ Debugging with Grafana / Prometheus
• See CPU spike
• Check error rate increase
• Inspect dashboards
• View latency P95/P99
• Look at Alert firing
⏱ Faster visibility
✅ Metrics clarity
❗ But…
You still manually correlate:
What changed?
Which deployment triggered this?
Which service is impacted?
Is this related to CI/CD?
Config drift?
Observability shows symptoms – not root cause.

🤖 3️⃣ Debugging with KubeHA
KubeHA combines:
✔ Cluster Changes (who changed what & when)
✔ CI/CD Activity
✔ Service Impact
✔ Error Rate / Latency / Throughput
✔ Config & Security drift
✔ Alerts correlation
✔ AI-based RCA
Instead of:
“CPU is high…”
You see:
Deployment X updated image at 10:02
Error rate increased at 10:04
Service Y impacted
Config drift detected
Likely root cause: Version mismatch
🎯 RCA in minutes – not hours
🎯 Cross-layer correlation
🎯 Change-driven debugging
🎯 Context-aware analysis
