Add the possibility to set Ident when logging to syslog. Reference http://www.gnu.org/software/libc/manual/html_node/openlog.html#openlog
It is possible to use --syslog --syslogFacility local3 when running mongod. It would be very nice to be able to use --syslogIdent myCustomNameOfMongodb
Or if using yaml config:
systemLog: destination: syslog syslogFacility: local3 syslogIdent: myCustomNameOfMongodb
