By default, Google Cloud creates two buckets: _Required (stores Admin Activity and System Event logs for 400 days) and _Default (stores all other ingested logs for 30 days). You can create custom log buckets to organize logs based on your specific requirements.
To configure log buckets, navigate to Cloud Console > Logging > Logs Storage. Here you can create new buckets, modify existing ones, or delete custom buckets. When creating a bucket, you specify the bucket name, location (region), and retention period ranging from 1 to 3650 days.
Key configuration options include:
1. Retention Period: Define how long logs are stored before automatic deletion. Longer retention increases storage costs but provides extended historical data access.
2. Region Selection: Choose where your logs are stored geographically for compliance and latency considerations.
3. Locked Buckets: Enable bucket lock to prevent modification or deletion of logs, useful for compliance requirements.
4. Log Sinks: Create sinks to route specific logs to designated buckets using inclusion and exclusion filters. This helps segregate logs by project, severity, or resource type.
5. Access Control: Apply IAM policies to control who can view, modify, or delete logs within specific buckets.
Best practices include creating separate buckets for different environments (production, development), setting appropriate retention periods based on compliance needs, and using exclusion filters to reduce unnecessary log ingestion costs.
To configure via gcloud CLI, use commands like 'gcloud logging buckets create' with appropriate flags for bucket-id, location, and retention-days. Regular monitoring of bucket usage through Cloud Monitoring helps optimize storage costs and ensure logging infrastructure meets operational requirements.
Configuring Log Buckets in Google Cloud Platform
Why It Is Important
Log buckets are essential for managing and organizing logs in Google Cloud. They allow you to control where logs are stored, how long they are retained, and who can access them. Proper configuration of log buckets helps organizations meet compliance requirements, optimize storage costs, and maintain security best practices. For the GCP Associate Cloud Engineer exam, understanding log buckets demonstrates your ability to implement effective logging strategies.
What Are Log Buckets?
Log buckets are containers in Cloud Logging that store log entries. Every Google Cloud project has two default buckets:
• _Required: Stores Admin Activity audit logs and System Event audit logs. This bucket has a fixed 400-day retention period and cannot be deleted or modified.
• _Default: Stores all other logs that are not routed elsewhere. The default retention is 30 days but can be customized between 1 and 3650 days.
You can also create user-defined buckets to organize logs based on your specific requirements.
How Log Buckets Work
1. Log Routing: When logs are generated, log routers evaluate each log entry against configured sinks to determine which buckets receive the logs.
2. Storage Location: You can specify the geographic region where your log bucket stores data, helping meet data residency requirements.
3. Retention Configuration: Each bucket can have a custom retention period. Once configured, logs older than the retention period are automatically deleted.
4. Access Control: IAM policies control who can view, modify, or delete log buckets and their contents.
Key Configuration Options
• Bucket Name: A unique identifier for the bucket within the project • Location: The region where logs are stored (e.g., us-central1, europe-west1, or global) • Retention Period: Number of days to retain logs (1-3650 days) • Locked Retention: Prevents the retention period from being reduced once set • CMEK: Customer-managed encryption keys for additional security
Exam Tips: Answering Questions on Configuring Log Buckets
• Remember the defaults: _Required has 400-day fixed retention; _Default has 30-day adjustable retention.
• Know bucket limitations: The _Required bucket cannot be modified or deleted. Only its views can be customized.
• Understand regional storage: When questions mention compliance or data residency, think about specifying a bucket location.
• Retention period scenarios: If a question asks about cost optimization, shorter retention periods reduce storage costs. For compliance needs, longer retention or locked retention may be required.
• Routing and sinks: Log buckets receive logs through sinks. To send logs to a custom bucket, you must create a sink with the bucket as the destination.
• CMEK considerations: Questions about enhanced security or customer-controlled encryption point toward using CMEK with log buckets.
• Locked retention: Once a bucket's retention is locked, it cannot be shortened. This is useful for regulatory compliance scenarios.
• Permissions required: Creating and managing log buckets requires the roles/logging.admin or specific logging permissions.
• Cross-project scenarios: Log buckets can receive logs from multiple projects when properly configured with appropriate sinks and permissions.
