Observability — Cloud Operations Suite

Collect metrics, logs, and traces with Cloud Monitoring, Logging, and Trace to run reliable systems.

Google's observability is the Cloud Operations suite (formerly Stackdriver). Cloud Monitoring collects metrics from GCP services and applications, supports dashboards and alerting policies, and underpins SLO/SRE practices (Google publishes the SRE methodology this tooling is built around). Cloud Logging centralises logs with the powerful Logging Query Language, log-based metrics, sinks (export to BigQuery/Cloud Storage/Pub-Sub), and retention controls.

An air-traffic control centre run by the people who wrote the safety manual (SRE): radar (metrics) flags anything off-target, the flight recorder (logs) holds every detail, the route tracker (traces) shows each request's path, and the whole operation is organised around explicit reliability targets rather than guesswork.

Key Concepts

For distributed systems, Cloud Trace provides latency tracing across services, Cloud Profiler continuously profiles CPU/memory in production at low overhead, and Error Reporting aggregates and deduplicates exceptions. Alerting policies evaluate metric or log conditions and notify channels (email, SMS, PagerDuty, webhooks) or trigger automation. Together these give the three pillars — metrics, logs, traces — plus profiling and error aggregation, with a strong SRE bent: define SLIs/SLOs, alert on burn rate, and use the data to diagnose and improve reliability.
