2024-06-26T09:34:16.36+00:00 @Rob Underwood, Apologies for the delayed response.
Are you still facing this issue or was it only for a small duration when you were facing this issue?
I checked the workbook, and it uses the query below to get these errors.
_LogOperation | where Level in ("Error", "Warning") | summarize arg_max(TimeGenerated, *) by Level, Resource=_ResourceId, Computer, Category, Operation, Details=Detail | project TimeGenerated, Level, Category=strcat(Category, " (", Operation, ")"), Computer=iff(Resource == "", Computer, strcat(Computer, " (", Resource, ")")), FullText=Details | reduce kind=source by FullText with threshold=0.5If you are still seeing the errors being reported, can you please run the following query to get an understanding of the resource which is causing this issue?
_LogOperation| where Level in ("Error", "Warning")| summarize arg_max(TimeGenerated, *) by Level, Resource=_ResourceId, CompuAs the table for which the error is being reported is AzureDiagnostics table, the values are being sent by another resource which is causing this error. The respective resource will have to be investigated to understand the cause.
Please let us know if you have any questions.
