The application serves traffic from Asia. Which metrics should you track to measure business and technical success for that region?

To measure both business and technical success for an application serving a specific region like Asia, a comprehensive set of metrics is required. Total visits from Asia directly indicate business success and user engagement in that region. Error rates from Asia measure technical reliability and user experience, as high error rates can lead to user dissatisfaction and lost business. Latency from Asia is crucial for technical performance, directly impacting user experience and application responsiveness. While latency difference between US and Asia might be interesting for comparison, it doesn't directly measure success within Asia. Total visits and average latency are good but omit critical error rate information. The number of character sets in the database is irrelevant to measuring application success or performance for a specific region.
