SPHealthAnalysisRule Class

An abstract base class that provides a definition for a SharePoint Health Analyzer rule.

System.Object
  Microsoft.SharePoint.Administration.Health.SPHealthAnalysisRule
    Microsoft.SharePoint.Administration.Health.SPRepairableHealthAnalysisRule

Namespace:  Microsoft.SharePoint.Administration.Health
Assembly:  Microsoft.SharePoint (in Microsoft.SharePoint.dll)

'Declaration
<SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel := True)> _
<SharePointPermissionAttribute(SecurityAction.InheritanceDemand, ObjectModel := True)> _
Public MustInherit Class SPHealthAnalysisRule
'Usage
Dim instance As SPHealthAnalysisRule

A SharePoint Health Analyzer rule is a a concrete subclass that inherits from either one of two abstract classes: SPHealthAnalysisRule or SPRepairableHealthAnalysisRule. The only difference between these two classes is that while both have a Check() method to detect a problem, the SPRepairableHealthAnalysisRule class also has a Repair() method to correct the problem found by the Check method.

When you create a subclass of the SPHealthAnalysisRule class, you must override and implement the Summary, Explanation, Remedy, Category, and ErrorLevel properties as well as the Check() method. If you want the rule to run automatically under a timer job, you should override and implement the AutomaticExecutionParameters property as well. Implementation of the remaining members of the class is optional.

The following example creates a rule that checks whether the local server is joined to the server farm.

Imports Microsoft.SharePoint.Administration
Imports Microsoft.SharePoint.Administration.Health
