Monitoring SharePoint2007

The Microsoft SharePoint 2007 monitoring model continuously monitors the performance of the SharePoint 2007 server, and proactively alerts administrators to issues.

Figure 2 : The layer model of SharePoint

Each layer of Figure 2 is mapped to a wide variety of tests that report a number of metrics related to the health of the SharePoint server in question. Using these metrics, the administrators can find quick and accurate answers for the following performance queries:

  • Are there too many documents in the first and second queues of the archival plugin? Do these numbers indicate that the crawler is in a starved state?
  • Were any error documents returned by the archival plugin?
  • How well is the document converter functioning? Are too many conversion requests pending on the converter?
  • How is the Excel calculation service performing? Is it responding to requests quickly? How effectively is the service using its cached charts? Are its workbook caches adequately sized?
  • Are the Excel Web Access and Excel Web Services components experiencing any slowdowns in request processing?
  • Is the content managed by SharePoint adequately indexed? Are search queries been successfully executed or are too many queries failing?
  • Is the gatherer service in a back-off state? If so, why?
  • Are your site hit frequency rules very rigid? Are they creating too many delayed documents?
  • Are too many threads waiting for documents?
  • Are too many threads waiting for a response from the filter process? Is it owing to a network issue or is it because they are bound to a hungry-host?
  • Was the gatherer unable to access any documents? If so, how many times?
  • Are there too many unprocessed documents on the gatherer?
  • Is the SharePoint Publishing Cache well-tuned? Is the cache hit ratio high?
