Why Application PerformanceMonitoring/Management ?
Today’s IT nframe-Tier“Shift to web based apps” Quick time to market, increased importance and reliance“Increased complexity” N-tier environments, access from anywhere anytime“Seas of data” Overwhelmed by various alarms and health information“Customer satisfaction, IT reports all is well, yet users are complaininghow do you know”“Wasting resources” Constant mis-diagnosis, false positives, finger-pointing, rework“Do more with less” Pressure to reduce operating costs and improve quality of servicePROBLEM Inconsistent performance of business applicationsPROBLEM Lack of understanding of the business impact of an incidentPROBLEM The time & resources to identify, isolate, and solve customer incidentsCopyright 2006 CA and Wily Technology, Inc.
