You cannot create a System Overview page, since every org has exactly one. What you can configure is how its warning messages read, so a colleague who lands on the page during a busy week gets a clear instruction instead of a generic alert. This is set up once and adjusted as your process changes.
- Open the System Overview page
From Setup, type System Overview into the Quick Find box and open it. Scan each section so you know which limits are closest to their ceilings before you write any message.
- Find the message setting
In Setup, search for the Configure System Overview Messages option. This is where you control the text shown when a resource crosses its threshold, so the warning can point to your own runbook.
- Write a message that prompts action
Replace the default note with text that tells the reader what to do next, such as linking an internal capacity-request page or naming who owns the cleanup. Keep it short and specific.
- Save and verify
Save the configuration, then confirm the message reads correctly. Revisit it whenever your capacity process changes so the guidance never goes stale.
The fastest route to the page in both Lightning Experience and Salesforce Classic; available in every edition except Personal Edition.
The setting that controls the text of the threshold warnings, so you can route readers to an internal process instead of a generic alert.
Most limits warn at 95 percent of the allocation; portal roles warn earlier, at 75 percent, because that ceiling is harder to raise.
- The page is read-only reporting. It shows usage but does not let you raise a limit or delete the resource that is filling up.
- A few limits behave differently from the plain counts displayed here, so treat a near-ceiling percentage as a prompt to investigate, not a hard guarantee.
- Portal roles can grow on their own as partner and customer accounts are enabled, so the 75 percent warning can arrive without anyone deliberately adding roles.
- Personal Edition does not include the System Overview page, so this guidance applies only to editions that expose Setup limits this way.
