syslog-ng issue in tagging to server -

-

i installed syslog-ng using "yum install syslog-ng" in both local machine , server end. using open source version of syslog-ng.

my need pass log file name client server end . explicitly set .sdata.file @ 18372.4.name field on client side, name of file available in $file_name macro. ".sdata.file @ 18372.4.name" empty in server side. when using static file name log beings work.

below code dont know going wrong if need more information can provide can me.

my client end syslog-ng code: source s_application_logs {      file(          "/var/log/test.log"         flags(no-parse)     ); };  destination d_access_system {     syslog(            "52.38.34.160"           transport("tcp")           port(6514)     ); };  rewrite r_set_filename {    set(        "$file_name",        value(".sdata.file @ 18372.4.name")       ); };  rewrite r_rename_filename {    subst(          "/var/log/",          "",          value(".sdata.file @ 18372.4.name")          type("string")          flags("prefix")         ); };  log {     source(s_application_logs);     rewrite(r_set_filename);     rewrite(r_rename_filename);     destination(d_access_system); };    server end syslog-ng code: source s_server_end {               syslog(                      port(6514)                      max_connections(1000)                      keep_hostname(yes)                     ); };  destination d_log_files {     file(         "/var/log/test/${.sdata.file @ 18372.4.name}"         create_dirs(yes)     ); };  log {source(s_server_end);destination(d_log_files);};

the problem $file_name macro available in commercial version of syslog-ng. possible workaround, see blogpost: forwarding filenames syslog-ng
