Cloud Monitoring

What I Do

I provide comprehensive visibility into cloud infrastructure and applications through metrics collection, log aggregation, distributed tracing, and alerting. I enable teams to understand system behavior, detect anomalies, and maintain service reliability.

When to Use Me

• Monitoring production systems and infrastructure
• Troubleshooting application issues
• Setting up alerting and on-call procedures
• Implementing SLOs and SLIs
• Analyzing system performance
• Distributed systems observability
• Compliance and audit requirements

Core Concepts

• Metrics: Quantitative measurements (CPU, latency, error rates)
• Logs: Textual records of events and errors
• Traces: End-to-end request tracking across services
• Service Level Indicators (SLIs): Metrics measuring service behavior
• Service Level Objectives (SLOs): Target reliability thresholds
• Error Budgets: Allowed unreliability before action required
• Dashboards: Visual representation of metrics and status
• Alerting: Notifications when thresholds are breached
• Synthetic Monitoring: Proactive testing from external locations
• Distributed Tracing: Tracking requests across service boundaries

Code Examples

Prometheus Configuration (YAML):

# prometheus.yml
global:
  scrape_interval: 15s
  evaluation_interval: 15s

alerting:
  alertmanagers:
  - static_configs:
    - targets: ['alertmanager:9093']

rule_files:
  - '/etc/prometheus/rules/*.yml'

scrape_configs:
  - job_name: 'kubernetes-nodes'
    kubernetes_sd_configs:
    - role: node
    relabel_configs:
    - source_labels: [__address__]
      regex: '(.*):10250'
      target_label: __address__
      replacement: '${1}:9100'

  - job_name: 'kubernetes-services'
    kubernetes_sd_configs:
    - role: service
    metrics_path: /metrics
    relabel_configs:
    - source_labels: [__meta_kubernetes_service_annotation_prometheus_io_scrape]
      action: keep
      regex: true

Best Practices

1. Define SLIs and SLOs early - Measure what matters for your users
2. Use structured logging - JSON format with consistent fields
3. Implement distributed tracing - Essential for microservices
4. Create runbooks for alerts - Don't page without action plans
5. Avoid alert fatigue - Tune thresholds, consolidate similar alerts
6. Use Golden Signals - Latency, traffic, errors, saturation
7. Monitor from multiple angles - Synthetic + real user monitoring
8. Retain data appropriately - Hot, warm, cold storage tiers
9. Test alerting regularly - Don't discover failures during incidents
10. Automate remediation - Self-healing for known failure modes
