‘“Is there a problem?” monitors are best answered by aligning the monitors to
the measurements of shareholder and stakeholder value creation. Real-time
business metrics and customer experience metrics should be employed.
• “Where is the problem?” monitors may very well be out-of-the-box third-party
or open source solutions that are relatively simple to deploy. Be careful with data retention and attempt to use real-time statistics when employing these measurements.
• “What is the problem?” monitors are most likely homegrown and integrated
into your proprietary application.’
