Today we’re pleased to announce availability of the Page Diagnostics Tool for SharePoint. The Page Diagnostics Tool for SharePoint is a Chrome Browser Extension designed to help you identify potentially problematic Classic pages in SharePoint Online that may not be delivering optimal performance based on characteristics discovered about the page by the Page Diagnostics Tool.
The Page Diagnostics Tool works by comparing discovered characteristics of one or more Classic pages in SharePoint Online to known best practices and provides guidance to remediating those issues to ensure you are delivering the best possible experience across these pages. In addition to addressing performance of existing pages, the Page Diagnostics Tool can also be used to evaluate existing pages before they are published in your environment.
For additional information on installing and using the Page Diagnostics Tool, refer to the getting started guide https://support.office.com/en-us/article/use-the-page-diagnostics-tool-for-sharepoint-online-dbab259....
The Page Diagnostic Tool also provides detailed information on a variety of characteristics useful for support and troubleshooting purposes to include the current CorrelationID, SPRequestDuration, SPIISLatency, page load time, and the current Url evaluated. For information on how to use this information, refer to support documentation for the Page Diagnostics Tool at https://support.office.com/en-us/article/use-the-page-diagnostics-tool-for-sharepoint-online-dbab259....
The baseline rules currently evaluated by the Page Diagnostics Tool are detailed below. Each rule has an associated “more info” link which will take you to the supporting page providing more insights on the rule.
