Build CloudWatch JSON and space-delimited metric filter syntax patterns.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Choose JSON Logs or Space-Delimited Access Logs.
Configure property paths ($.status_code) and operators.
Paste into CloudWatch Metric Filter or Subscription Filter.
{ $.status_code >= 500 } matches all 500-level HTTP error responses.
Yes, syntax like { $.level = 'ERROR' } filters by exact string matches.
