System Overview is a single-page admin dashboard summarizing org health — API usage, scheduled jobs, data and file storage, custom code limits, permission set assignments. Good first stop for "is anything weird?" health checks.
- Open Setup → System Overview
Setup gear → Quick Find: System Overview → System Overview.
- Review API Usage
Last 24 hours of API call volume vs license limit. Approaching limit means an integration is misbehaving.
- Review Schema (Custom Objects, Custom Fields, Code)
Counts vs limits. Hitting the Custom Field limit blocks new field creation.
- Review Business Logic (Apex classes, triggers, scheduled Apex)
Code health. Validation errors here mean Apex is broken.
- Review User Interface (Tabs, Custom Apps, Page Layouts)
UI customization counts.
- Review Most Used Licenses and Permission Sets
Who's using what. Identifies unused licenses for reclamation.
- Drill into any section for details
Each section is a link to the underlying Setup page.
Past 24h API calls. Edition-specific limits.
Custom Objects, Fields, Code, Page Layouts vs limits.
Apex code health and scheduled Apex.
Active assignments per license type.
- API Usage is a 24-hour rolling window. Hitting the limit blocks API calls — including integrations. Slow integrations or polling loops are common culprits.
- Custom Field limits per object are real. Hitting them blocks new field creation — must delete unused fields or pay for higher edition.
- System Overview is read-only. It surfaces issues but doesn't fix them — fix at the underlying Setup page.
