is that information going to be dynamically generated each time an user does login, or it's going to be updated in a file every X minutes, and the motd message will just happen to be the latest version available? Personally I have some servers I never login into, unless I know there is a problem with it, or I know security updates are available, which make that message a bit pointless to display at login time only. If that "motd" info was available in a file, then I could find a way to push that into a centralized server where I could see it no matter when I do an actual login. And actually that type of expanded motd message may be more useful on my desktop computer where I login more often than on a server that just happily runs in a corner of the server room serving services or disk space without human intervention for days at end. > The goal of this tool is to provide the administrator a basic overview > of how the system is running.

These days I'm playing with the getting old Big Brother (www.bb4.org) to centralize messages from various servers into one web page. Now looking at some of the info I have been tracking that way from my servers: connectivity, system load, disk usage (i.e, specific important disks are nearly full while other disks I can ignore), if specific processes are still running (by default big brother tracks cron), and if specific services are online and listening (ftp, http, ssh). I could see some of these bits of info being useful in that motd message. It is on my to-do list to tied into Dell's OMSA and track down as well more hardware specific basic info (temperature, state of disks and raid, are the fans working, etc).
