Common Uses Application Performance Monitoring (APM) • Visually display real-time performance data • Stack traces of dissatisfying transactions, queries, and errors • Track database query performance • Yesterday and Weekly comparison of performance • Compare performance against throughput (scalability) • Track “key transactions” for your most important pages • Create alerts based on satisfaction metrics, error rate, or availability • View reports based on SLA, availability, and scalability

- 9. #wpewebinar Quickly Troubleshoot SiteErrors Use Error Analytics to view errors by type, frequency, and times occurred. Choose errors in your list to view a stack trace to locate which files are triggering the error Troubleshoot Load Time Spikes Using Alerts to be notified of spikes Three ways to inform performance strategy Using Error Analytics Use Alerts (new) to be alerted of load time spikes or Apdex drops. Use Overview to see which aspect (PHP, MySQL, or Web External) is causing the performance issue Troubleshoot Consistent Slowness Using Transaction Traces Use Transaction traces to get a stack trace of which queries, and theme and plugin functions are being called on which pages. Use the Trace details tab to see the timestamps in the trace
