acs:cdn:{RegionID}:{AccountID}:{Filter}

The {Filter} component specifies which CDN resources can fire the trigger:

Format: {FilterName}/{FilterValue}
Multiple values: Separate values with commas and enclose them in braces. For example, domain/{example.com,aliyun.com} fires the trigger for both domains.
Single value: Omit the braces. For example, domain/example.com fires the trigger only for example.com.
Multiple filters: Separate filters with forward slashes (/). The logical operator between filters is AND. Format: acs:cdn:{RegionID}:{AccountID}:{Filter1}/{Filter2}/{Filter3}...

Example — single domain:

The LogFileCreated event fires the trigger only when example.com generates a log file:

acs:cdn:*:1234567890:domain/example.com

Example — multiple domains:

The trigger fires for log files from both example.com and aliyun.com:

acs:cdn:*:1234567890:domain/{example.com,aliyun.com}
