Monitoring SharePoint2007

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

Figure 1 : The layer model of SharePoint

Each layer of Figure 1 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?
