SharePoint Storage Warning
Use this baseline to monitor the storage usage of selected SharePoint sites. Specify a usage threshold (as a percentage of quota) and the baseline will alert when a site exceeds that threshold. Configure the site list, quota, and threshold values per tenant to ensure you identify capacity risks before they become business-impacting.

Configure it
This baseline watches SharePoint site storage rather than a single setting. It applies to the whole tenant.
-
Add the baseline to the tenant (Adding a baseline), or deploy it to many tenants at once as part of a scheme (Deploying a scheme).
-
Set the Storage warning threshold to
90: the percentage of a site’s storage quota Octiga lets it reach before this baseline deviates. 90 is the default; you can give individual sites their own threshold, or leave specific sites out of monitoring. -
Choose the sites you want watched. A site with no threshold of its own uses the default from step 2.
-
Save. This baseline has no Auto-remediation switch: SharePoint and OneDrive storage is capacity your organisation buys through its Microsoft licensing, not a setting Octiga can write back. To clear a deviation, free up space on the site or buy more storage.
Check it worked
Passing means every site this baseline watches is at or below its threshold. See the live figure for a site in the SharePoint admin centre, under Active sites, on the site’s own storage bar. When a watched site crosses its threshold, the baseline shows Deviated and raises an alert. Users see nothing from Octiga, though a site that’s full may start blocking uploads and showing its own low-storage messages in Microsoft 365.
