Introduction

Let’s be honest — managing Kubernetes observability can feel like trying to catch smoke with your bare hands. Your team deploys faster, scales broader, and the volume of metrics grows beyond control. Soon, dashboards become cluttered, slow to load, and, worse, show everything but what you truly need during critical incidents.

We’ve seen this story unfold in countless engineering teams. But the good news? It doesn’t have to be this way.

This guide will walk you through:

• Understanding why certain metrics matter (and why others don’t).
• Building dashboards that make sense to both engineers and stakeholders.
• Automating reporting to keep your leadership looped in — without adding to your to-do list.
• Avoiding the common mistakes that cause teams to drown in data but starve for insights.

Let’s roll up our sleeves and transform chaos into clarity.

Why Observability Breaks — and How to Make It Work for You

Where teams stumble:

• Metric overload: Just because you can collect something, doesn’t mean you should.
• Sluggish dashboards: Queries that drag during an incident are more than frustrating; they’re dangerous.
• Alert fatigue: Flooded inboxes with alerts no one reads.
• Siloed monitoring: One team’s metrics aren’t visible to others.

What you actually need:

• Clear dashboards that answer: Is everything okay? If not, where and why?
• PromQL queries that run fast and light.
• Alerts that trigger action, not eye-rolls.
• Data shared in formats everyone — from SREs to execs — can digest.

👉 We help teams build observability stacks that truly work.

Metrics That Matter (And What to Ignore)

Keep your eye on:

• Node-level red flags: CPU throttling, disk I/O bottlenecks, memory saturation.
• Pod churn: Frequent restarts, OOM kills, and hanging terminations.
• API control plane latency: If the API is slow, the entire cluster feels it.
• Persistent volume saturation: Because running out of storage mid-deploy is not fun.
• DNS hiccups: The silent cluster killers.

Skip the noise:

• Obscure metrics nobody understands or uses.
• Redundant visualizations that repeat the same data three times.
• Overly detailed log streams crammed into a monitoring dashboard.

Tip: Every metric should answer the question: What would I do if this number spiked?

The 10 Must-Have Dashboards (Explained Like You’re in the War Room)

1. Kubernetes Cluster Monitoring Dashboard

• See: to monitor pod cpu, memory, I/O, RX/TX and cluster cpu, memory request/limit/real usage, RX/TX, Disk I/O
• Use: Every morning and right after every big deployment.

2. Node Exporter

• See: Disk IO latency, CPU load, filesystem status.
• Use: Troubleshooting misbehaving nodes.

3. Pod Stability

• Uptime Monitoring Uptime: Displays the uptime of your pod.
• Resource Usage CPU Usage: Monitor pod CPU usage. Memory Usage: Track pod memory consumption.
• Network I/O Inbound Traffic: View the amount of data received over the network. Outbound Traffic: Track the data sent out over the network.
• Search by Duration and Namespace Time Range Selector: Easily select predefined time ranges or set custom start and end times to view data. Namespace Filter: Filter metrics by specific namespaces to focus on relevant data.

4. PVC Usage

This dashboard can be used to check statistics of all PVCs and PVs that are present in a Kubernetes cluster. In order to see some data in the dashboard, first you need to configure Prometheus to scrape data from Kubelet service of all nodes within your Kubernetes cluster.

5. Namespace Resource Usage

For companies that control resource utilization ($$$) in Kubernetes namespaces through resource quotas, this dashboard helps you and your end users to quickly spot how close they are to hitting their quota limits.

6. Deployment Success Rates

• A parameterized dashboard for common workload types (deployment, daemonSet, statefulSet) that has charts that pull Prometheus metrics from Kubernetes, Istio, and node-exporter and visualizes metrics in several categories (by panel):
• At a Glance – A quick view of the health of your Kubernetes-based app (assumes it’s web service, so it’s mostly Istio metrics like success, latency, etc)
• RED (Requests, Errors, Duration) – SRE “Golden Signals” that come from Istio
• USE (Utilization, Saturation, Errors) – SRE “Golden Signals” that come from Kubernetes
• Infra Resources – POD distribution by host and AZ, HPA metrics, image tag, oomkills, CPU throttling, total deployment allocated CPU’s & memory, and more

7. API Server Performance

This dashboard helps visualize Kubernetes apiserver performance. It provides several metrics including: apiserver request rates, apiserver and etcd request latencies (p95, p90, p50), workqueue latencies (p95, p90, p50), etcd cache hit rate

8. Ingress Traffic

This Dashboard contains metrics visualization of Nginx Ingress Controller Running in Kubernetes Using Prometheus as Datasource. If you have prometheus and grafana installed on your cluster then prometheus will already be scraping this data due to the scrape annotation on the deployment.

Here you will see this information in dthe ashboard

• Controller Request Volume
• Controller Connections
• Contoller Success Rate(non-4|5xx responses)
• Config Reloads
• Last Config Failed
• Ingress Request Volume
• Ingress Success Rate (non-4|5xx responses)
• Ingress Percentile Response Times and Transfer Rates
• Network I/O Pressure
• Average Memory Usage
• Average CPU Usage

9. CoreDNS Health

A dashboard for the CoreDNS DNS server with updated metrics for version 1.7.0+. Based on the CoreDNS 1.7.0+ dashboard by ejkinger

10. Central Alert Board

See: What’s broken, severity level, and who’s on call. Use: During incident calls.

👉 We custom-build dashboards that filter noise and elevate action.

Automate Reports — Because Screenshots in Slide Decks are a Waste of Time

Your execvutives aren’t logging into Grafana — and they shouldn’t have to. But they do need updates.

Skedler automates:

• PDF, Excel, or CSV reports — generated straight from your dashboards.
• Scheduled delivery to Slack, email, or cloud storage.
• Clean, branded formats tailored to the audience.

👉 Start automating reports and reclaim hours.

Dashboard Maintenance Tips (The Part No One Talks About)

• Audit quarterly: What’s still relevant? What’s noise?
• Add annotations: Deployment markers help connect cause and effect.
• Measure dashboard load times: Slow panels are warning signs.
• Organize panels logically: Resource usage, pod health, network — in that order.
• Set refresh rates thoughtfully: Not everything needs 10-second updates.

👉 We help teams do exactly that. Book a call with us.

What This Looks Like in the Real World

Any fast-scaling SaaS company managing complex, multi-cluster environments was struggling. Their engineers were trapped in reactive firefighting — slow incident response, unexpected outages, and surprise cloud costs were the norm.

They needed visibility, predictability, and efficiency.

By implementing automated reporting and proactive monitoring, they turned the tide:

✅ 40% faster incident response times — freeing up engineers to focus on building, not battling fires.

✅ $25,000 saved annually — by identifying and eliminating cloud resource inefficiencies before they escalated.

✅ Leadership visibility on autopilot — with weekly PDF reports delivered automatically, no manual work, no chasing updates.
