Description: Select messages labeled with the specified tag. Every message automatically has the tag of its source in .source.<id_of_the_source_statement> format. This option is available only in AxoSyslog 3.1 and later.
Example: Adding tags and filtering messages with tags
The AxoSyslog application automatically adds the class of the message as a tag using the .classifier.<message-class> format. For example, messages classified as “system” receive the .classifier.system tag. Use the tags() filter function to select messages of a specific class.
