Starwood currently uses Introscope 6 monitoring tools, which were added after it launched a new online reservation system in 2001 that crashed nearly every four hours, Kelly said. Today, the system accounts for about 10% of all revenue and is used to book about $1 billion in annual reservations.

Introscope 6 is being used on eight application servers for the Web-based system and 32 Java virtual machines. Kelly said he is interested in testing new capabilities in the latest version, which offers expanded data views including how long it takes a user to get a Web response. Introscope 7 also provides automatic discovery, monitoring and triage of system problems with no manual configuration, according to CA. Pricing was not released.
