Key Performance Categories � Mobile Code Back-end Network Execution Services Requests (UI & background work) �
Network Performance � • HTTP Error Rate � • Avg ResponseTime � • Requests Per Minute � � • Data Transfer Size � • Network Failure Rates
Mobile Code Execution � • View Load Time � • Database Request Time � • JSON Parsing Speed � � • Image Load Time � � • % CPU Usage � � • Memory Usage
Monitor first for a baseline, validate acceptable range through user studies
Organize foreground and background work for seamless user experience
Metrics Actions & Decisions Desired Outcome
Happy Brit Young Monitoring! @brittanytarvin brittany@newrelic.com
