The Usage App ships ready to go. The work is establishing a regular review cadence and acting on what the dashboards show.
- Open the Lightning Usage App
Setup, Quick Find, Lightning Usage. The app opens with the default dashboards.
- Review the EPT dashboard
Sort pages by EPT descending. Anything above 5 seconds is a candidate for investigation.
- Investigate slow pages
Open the slow page in Lightning App Builder. Inspect the components present; identify custom LWCs or heavy related lists.
- Run Salesforce Optimizer
Setup, Optimizer, request a fresh report. Review the recommendations and prioritize the high-impact ones.
- Track Daily Active Users and Switcher Usage
Monitor weekly. Drops in DAU or spikes in Switcher Usage signal user-experience problems that need attention.
- Report to executives quarterly
Build a quarterly executive review using the Usage App dashboards. The data tells the platform-health story with no extra reporting work.
- EPT measures real-world performance, not synthetic benchmarks. A page that benchmarks well in sandbox may have high EPT in production due to data volume or user-specific permissions.
- The Usage App is a snapshot of recent activity, not real-time. Data refreshes daily; do not expect instant feedback after a change.
- Switcher Usage is the canary metric for Lightning adoption problems. A user who switches back to Classic frequently is telling you something about Lightning UX.
- Salesforce Optimizer is recommendation-only. The Optimizer does not change anything; the admin still has to act on the recommendations.
