WebFacing – Disk, resource usage and errors from cPanel® on your Dashboard & in Site Health


🕸️ By WebFacing. Shows disk usage, memory, cpu and processes resource usage information, recommendations and alerts, plus number of created email accounts, in your admin Dashboard At a Glance widget, a special Dashboard Gauges widget, plus error logs and extensive info on Tools – Site Health panels.

Includes an email routing test (when server is not authority, routing must be remote).

Also includes a Site Health test for HTTPS only (http should not be allowed, but forwarded to https) with information about the issue, recommendation and actions.

Made with a little help from cPanel, L.L.C., USA and PRO ISP AS, Norway – many thanks.

This plugin is a candidate to be recommended to all customers by PRO ISP AS, Norway.

    Known limitations

  • Links to documentation to resolve reported issues are shown to PRO ISP AS customers only.
  • This plugin will probably not report much if the site is not on a cPanel® managed server, but will do the test for HTTPS only.
  • Resource gauges in dashboard widget suffers interference from Site Kit plugin by Google. Gauges not shown.


  • Dashboard - At a Glance widget
  • Site Health Disk Space Test
  • Site Health Email Routing Test
  • Site Health HTTPS only test
  • Dashboard - Resource usage & errors widget


Does this plugin add database tables, store options or adding lines to `wp-config.php`?

No, not, none.

Does it require my login information to cPanel®?


What if I don’t want the (new) cPanel® Resource Usage widget (gauges)?

Close it with the up arrow icon, or hide it using Screen Options (the top right hidden panel) – as usual. No data will be fetched from cPanel® while widget is closed or hidden.

Does it work on other web hosts than PRO ISP?

Yes, at least on some, but not tested much. Please report your experience. Use Reviews, Support or GitHub.

Does it work without cPanel®?

Very, very limited. The ‘HTTPS only’ security test should work, and disk used info, but max space test will not be performed and the result will just show ‘N/A’.

Can I contribute to this plugin?

Yes, visit it’s Github repo and create an issue, clone it and/or file a pull request.
