Section 2: Unlocking the Potential of Your Data
Seamlessly integrate Grafana with powerful data sources for full-stack visibility:
| Data Source | Why You’ll Love It | How to Set It Up |
|---|---|---|
| Prometheus | Real-time metrics for proactive insights | Simple URL-based setup |
| Loki | Effortless log management | Deploy Promtail and you’re all set! |
| Elasticsearch | Advanced analytics for deep log diving | Configure indices and secure easily |
| Jaeger/Tempo | Unparalleled tracing for microservices | Deploy agents seamlessly |
| CloudWatch | AWS insights, simplified | Quick IAM configuration |
Section 3: Crafting Dashboards That Inspire Confidence
3.1 Visual Storytelling at Its Finest
Great dashboards tell stories—highlighting trends, pinpointing issues, and driving decisions. Grafana’s dashboards bring your data to life through engaging visuals.
3.2 Examples You’ll Love (PromQL)
- CPU Monitoring:
100 - avg(rate(node_cpu_seconds_total{mode="idle"}[5m])) * 100- Memory Insights:
node_memory_MemAvailable_bytes / node_memory_MemTotal_bytes * 100- Disk Health:
(node_filesystem_size_bytes - node_filesystem_free_bytes) / node_filesystem_size_bytes * 100Section 4: Alerting Made Easy
Never miss critical issues with Grafana’s sophisticated alerting system:
- Quick Alert Setup (High CPU):
expr: avg(rate(node_cpu_seconds_total{mode!="idle"}[5m])) by(instance) * 100 > 85
for: 5m
labels:
severity: critical
annotations:
summary: "CPU Utilization Critical!"Integrate seamlessly with Slack, PagerDuty, and email for swift action.
Section 5: AIOps Magic—Automation Meets Intelligence
Supercharge Grafana with advanced AI-driven anomaly detection:
- Memory Anomaly Detection:
abs(rate(node_memory_MemAvailable_bytes[1h]) - node_memory_MemAvailable_bytes) > 0.2 * avg_over_time(node_memory_MemAvailable_bytes[1h])Automate responses and keep your team agile using tools like Robusto and PagerDuty.
