Escape from ETL Hell: The Real Time Enterprise. Five 9's--the universal symbol of reliability in high-tech. Five 9's represents 99.999% uptime or just a little over five minutes of allowed downtime per year. Achieving five 9s isn't easy. Operations organizations that do achieve it do it, in part, by carefully instrumenting and monitoring systems using expensive software like HP OpenView and IBM's Tivoli. These kinds of systems aren't cheap, but operations managers know that you can't manage what you can't measure and with only five minutes to spare in any given year, they'd better have that information in real time.
