JencoMart has built a version of their application on Google Cloud Platform that serves traffic to Asia. You want to measure success against their business and technical goals. Which metrics should you track?

To measure success against business and technical goals for an application serving traffic to Asia, you need a comprehensive view. "Total visits" directly reflects business success by indicating user engagement and reach. "Error rates" are crucial technical metrics, showing the reliability and stability of the application. High error rates suggest a poor user experience and potential technical issues. "Latency from Asia" is another vital technical metric, directly impacting user experience and application performance for the target region. While "Error rates for requests from Asia" is important, it's not comprehensive enough on its own. "Latency difference between US and Asia" might be interesting for comparison but doesn't directly measure the success of the Asia-specific deployment. "Total visits and average latency for users from Asia" is better but omits error rates, which are critical for assessing technical health. "The number of character sets present in the database" is irrelevant to measuring application success or user experience.
