Help & Educate users

Generate system reports and correlate growth, changes over time. (Use data to order supplies, spares, hardware and software upgrades in a timely manner, and to generate reports to management)

Problem Solving

books, netnews, man pages, on-line (www.tldp.org, docs.sun.com, www.redhat.com, ...)
