Nop,
Again same problem:
Here is what i have done

destination d_mongodb {
        mongodb(
        servers("localhost:27017")
        database("syslog")
        username("Ivan")
        password("Ivan123")
        collection("messages")
        value-pairs(
            scope("selected-macros" "nv-pairs" "sdata")
            pair("date", datetime("$UNIXTIME"))
            pair("pid", int64("$PID"))
            pair("program", "$PROGRAM")
            pair("message", "$MESSAGE")
                )
                        );
                        };
Still have the same problem no info on date no nothing. The strange part
is that when i open a specific log i have all the info. The only problem
is where on a first page on the LogAnalyzer i don't have this problems.

And yes again we may have two problems: One is the DB information how
its stored, and by this i think we stored as we should, but do i have to
configure some tables in the MongoDB or columns or something ( that is
how i did it with MySQL ). The second is something wrong with the
LogAnalyzer so now im going to reconfigure with PostgreSQL and again
with MySQL to see if something will be change.
