Cloud Operations

Google Cloud Operations (formerly Stackdriver) is a suite of observability tools for monitoring, logging, tracing, and debugging GCP applications. It provides integrated monitoring and management across your entire stack.

Key Components:

1. Cloud Monitoring - Collect metrics, dashboards, and alerting policies.

2. Cloud Logging - Aggregate and analyze logs from GCP services.

3. Cloud Trace - Distributed tracing to analyze latency in microservices.

4. Cloud Profiler - Continuous CPU and heap profiling for production apps.

5. Error Reporting - Automatically groups and reports application errors.

The below example shows how to set up a monitoring alert for high CPU usage using gcloud.

It gives the following output,

Alert policy created: projects/my-project/alertPolicies/1234567890

Recent ERROR logs:
TIMESTAMP              SEVERITY  MESSAGE
2024-01-15T10:05:23Z   ERROR     Connection timeout to database
2024-01-15T09:58:12Z   ERROR     OOM killed - container restarted

Cloud Operations Suite Components Summary:

Cloud Monitoring - 1500+ built-in metrics for GCP services. Custom metrics via OpenTelemetry or the Monitoring API. Uptime checks for external endpoints.

Cloud Logging - Log-based metrics, log sinks to BigQuery/GCS/Pub/Sub for export. Log retention configurable from 1 day to 10 years.

Cloud Trace - End-to-end latency data across distributed services. Integrates with OpenTelemetry and Zipkin.
