AWS AmazonCloudWatch documentation change

Service: AmazonCloudWatch · 2026-04-04 · Documentation low

File: AmazonCloudWatch/latest/monitoring/processor-examples.md

Summary

Added new examples for conditional processing including filtering debug/trace logs and removing sensitive fields (password, api_key, ssn) in production/staging environments.

Security assessment

The change adds examples showing how to remove sensitive fields (PII/credentials) using conditional processing, which demonstrates security best practices for data protection. However, this is general documentation enhancement rather than addressing a specific security issue.

+###### Example Conditional processing with entry-level conditions
+
+Add different metadata based on log severity using entry-level `when` conditions:
+    
+    
+    processor:
+      - add_entries:
+          entries:
+            - key: "alert_level"
+              value: "critical"

+              value: "info"
+              when_else: "log.level == 'ERROR'"
+
+###### Example Drop unwanted log entries
+
+Filter out debug and trace log entries from a third-party source to reduce noise and storage costs:
+    
+    
+    processor:
+      - drop_events:
+          when: "log.level in {'DEBUG', 'TRACE'}"
+          handle_expression_failure: "skip"
+
+###### Example Processor-level conditional with delete_entries
+
+Remove sensitive fields only when the environment is production:
+    
+    
+    processor:
+      - delete_entries:
+          with_keys: ["password", "api_key", "ssn"]
+          when: "environment in {'prod', 'staging'}"
