    syslogd and klogd are logging services. klogd is the kernel-space version, syslogd is the user-space version. Any process starting with k is something used by the kernel: kswapd, klogd, kscand, etc. rhnsd is something for the Red Hat Network, but I forget the exact purpose. I would suggest googling or looking at the man pages for those other processes.

    rhnsd --interval 240 = a program for quering the Red Hat Network for updates and information
    syslogd -m 0 - is your system logs
    klogd -x = is kernel logs
    mdadm - https://rhn.redhat.com/errata/RHEA-2003-397.html
    atd = http://www.comptechdoc.org/os/linux/...nux_suatd.html
    xfs = A high-performance journaling filesystem

    Hope that helps
