Currently, LogMonitoring.logMonitor supports only pattern that does filter @message like /pattern/ which is not ideal for JSON logs. Thanks to AWS Powertools for Lambda, JSON logs are becoming widely used and this feature will help logMonitor to be more performable and sustainable.
This issue suggests a new prop that expects operator as string and value as Record<string, string | string[]> that will enable more specific log queries.
