tags()

Synopsis: tag

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 syslog-ng OSE 3.1 and later.

Example: Adding tags and filtering messages with tags

source s_tcp {
    network(ip(192.168.1.1) port(1514) tags("tcp", "router"));
};

Use the tags() option of the filters to select only specific messages:

filter f_tcp {
    tags(".source.s_tcp");
};

filter f_router {
    tags("router");
};

NOTE: The syslog-ng OSE 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.

filter f_tag_filter {tags(".classifier.system");};
