Google Cloud Monitoring & Logging

Google Cloud's operations suite (formerly Stackdriver) provides full-stack visibility into your applications. It helps you understand health, performance, and availability by collecting signals from your entire cloud infrastructure.

Google Cloud Monitoring & Logging

1. Cloud Monitoring (Metrics)

Monitoring is about numbers over time. It tracks metrics like CPU usage, memory consumption, and request latency to show you the "health" of your system.

  • Dashboards: Visual charts to spot trends.
  • Alerting: Notifications (Email, Slack, SMS) when a threshold is crossed (e.g., CPU > 90%).
  • Uptime Checks: Probes that check if your website is reachable from different global locations.

2. Cloud Logging (Events)

Logging is about records of events. It stores text-based records of what happened, when it happened, and who did it. It is your primary tool for debugging and auditing.

  • Log Explorer: A powerful interface to search and filter through millions of log entries.
  • Log Sinks: Export logs to BigQuery (for analysis) or Cloud Storage (for long-term archiving).
  • Audit Logs: Records of administrative actions for security compliance.
