[syslog-ng] is it possible to normalize the jSON keys to lowercase?

10 Jan 2017

      Hi,

   I am using the 'format-json' as my below snip.

template t_raw2json {
    template("$(format-json --scope selected_macros \
                            --exclude TAGS          \
                            --exclude DATE          \
                            --exclude PRIORITY      \
                            --exclude FACILITY      \
                            --exclude PROGRAM
    )\n");
};

but, the problem is because sometimes I receive a jSON packet as { "Key":
"value" } or {"key": "value}".... this has been a problem to my filter.

e.g:

destination d_nginx_modsec_log {
    file("/var/logs/myapp//${j.key:-invalid_key}.log"  template(t_raw2json)
 );
};

Question: is it possible to normalize the jSON keys to lowercase? or
someone has other approaches?
