Measures reported by SPOHealthStatusTest

Information that a browser sends back in the response headers for each file can serve as an effective tool for diagnosing performance issues with SharePoint Online. The three most useful values contained in response headers are:

  1. X-SharePointHealthScore: This is the value, from zero to ten, that indicates how heavily loaded the SharePoint Server is at the time when the page was served.

  2. SPRequestDuration: This is the amount of time (again, in milliseconds) that it took to process the request on the server. Basically, this is the end-to-end processing time for the page.

  3. SPIislatency: This is a measure of the amount of time (in milliseconds) that the request spent queued and waiting to be processed by IIS (Internet Information Services - the web server).

Using the SPOHealthStatusTest test, administrators can easily track these values, proactively capture potential performance issues with SharePoint Online, and rapidly initiate measures to fix them before any irreparable damage is done.

Outputs of the test : One set of results for the SharePoint server on the cloud.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
SP_health_score Indicates the current health score of the SharePoint server. Number This number ranges from 0 to 10 where 0 indicates the server is idle and 10 indicates the server is very busy. A HealthScore that is consistently 9 or 10 might indicate an ongoing performance issue with the server. Any other number indicates that server is operating within the expected range.
SP_request_duration Indicates the amount of time (again, in milliseconds) that it took to process the request on the server. Seconds Healthy pages range from a couple hundred milliseconds to around a second depending on the content of the page.
SP_iis_latency Indicates time (in milliseconds) that the request spent queued and waiting to be processed by IIS server. Seconds Ideally, the value of this measure should be zero or very close to zero.
