filter_begin: < Marks the beginning of a filter configuration. Everything until filter_end belongs to the same filter. Mandatory. >
filter_module_name: < Name assigned to the module that generates the filter. Mandatory. >
filter_module_type: < Type of module that generates the filter. Mandatory. >
filter_topic: < Regular expression or exact text that must match the message topic for the filter to apply. Optional. By default, it matches any topic. >
filter_topic_exact_match: < Defines whether filter_topic is treated as a regular expression (0) or exact text (1). Optional. Default is 0. >
filter_message: < Regular expression or exact text that must match the message content for the filter to apply. Optional. By default, it matches any message. >
filter_message_exact_match: < Defines whether filter_message is treated as a regular expression (0) or exact text (1). Optional. Default is 0. >
filter_message_capture_regex: < Regular expression with capture groups to extract values from the message. >
< Captured values will be stored in macros '__regexN__', where N is the capture group index. >
filter_message_capture_json: < List of JSON paths (separated by '|') to extract values, using the same format as jq. >
< Captured values will be stored in macros '__jsonN__', where N is the path index. >
filter_module_value: < Value assigned to the module that generates the filter. Mandatory. >
filter_end: < Marks the end of a filter configuration. Everything from filter_begin belongs to the same filter. Mandatory. >
# Available macros for use in filter_module_name and filter_module_value:
__topic__: < Replaced with the exact topic of the processed message. >
__regexN__: < Replaced with the corresponding value captured by filter_message_capture_regex. >
__jsonN__: < Replaced with the corresponding value captured by filter_message_capture_json. >
