Question 150
A company wants to analyze logs from multiple services in real time. Which service should be used?
A) Cloud Logging
B) Cloud Monitoring
C) Cloud Trace
D) BigQuery
Answer: A
Explanation:
Analyzing logs from multiple services in real time requires a service that aggregates, indexes, stores, and provides querying capabilities for operational and application logs. Cloud Logging is a fully managed logging service that collects logs from Google Cloud services, custom applications, and third-party sources. It allows enterprises to filter, search, and visualize logs in near real-time, supporting troubleshooting, performance analysis, and security audits. Cloud Monitoring focuses on metrics rather than raw log content, Cloud Trace tracks latency and distributed requests, and BigQuery is optimized for analytical queries on large datasets rather than real-time log aggregation. Cloud Logging ingests logs continuously and stores them securely, providing flexible retention policies, indexing, and export capabilities. Logs can be queried using Log Explorer or exported to BigQuery for long-term analytics, Cloud Storage for archival, or Pub/Sub for streaming to external systems. IAM policies enforce secure access to logs, while logging sinks can route logs to multiple destinations. Real-time alerts can be configured to notify administrators of critical events, anomalies, or policy violations. Integration with Cloud Monitoring enables correlation between logs and metrics for root-cause analysis. Cloud Logging supports structured and unstructured logs, custom log entries, and logging from multiple services, ensuring comprehensive observability across an organization’s infrastructure. Dashboards and visualizations allow teams to monitor application behavior, error patterns, and operational trends. Enterprises can implement automated workflows triggered by log events, such as invoking Cloud Functions or sending notifications for specific log conditions. High throughput, automatic scaling, and retention controls ensure consistent performance and reliability for large-scale logging environments. Cloud Logging enables auditing, compliance, and operational insight, providing a single pane of glass for analyzing logs from multiple sources in real-time.
