    [bug?] System.Web.HttpRequestValidationException on adding a filter on High Errors/Discards resource

    Reply

     

    Hello.

    I was trying to add my own filters to a resource on Orion, and I see that this error included below occurs on every filter attempt.  I thought it was my own syntax until I tried the sample filters provided.  The resource in question is High errors and discards todayOrion Website Error

    An error has occurred with the Orion website.

    Additional Information

    System.Web.HttpRequestValidationException: A potentially dangerous Request.Form value was detected from the client (SubTitle="... XX Today 
     (3548 ERRORS ...").
   at System.Web.HttpRequest.ValidateString(String s, String valueName, String collectionName)
   at System.Web.HttpRequest.ValidateNameValueCollection(NameValueCollection nvc, String collectionName)
   at System.Web.HttpRequest.get_Form()
   at System.Web.HttpRequest.get_HasForm()
   at System.Web.UI.Page.GetCollectionBasedOnMethod(Boolean dontReturnNull)
   at System.Web.UI.Page.DeterminePostBackMode()
   at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

   at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

    A few example filters are :

    Filter the results to only show Nodes that are not UP
    Status<>1

    The valid status levels are :

    0 = UNKNOWN (The current up/down status of the Node is unknown)
    1 = UP (The Node is responding to PINGs)
    2 = DOWN (The Node is not responding)
    3 = WARNING (The Node may be responding, but the connection from the server to the Node is dropping packets)

    Only show Cisco devices
    Vendor = 'Cisco'

    Only show devices in Atlanta. (This assumes you have added a custom property named City)
    City = 'Atlanta'

    Only show devices beginning with "AX3-"
    Caption Like 'AX3-*'

    Only show Nortel devices that are Down
    Vendor Like 'Nortel*' AND Status=2

    Only show devices ending in '-TX'
    Vendor Like '*-TX'

    -I was using "Interface Errors <br /> Except 3548s -jp" as the description for the resource.

    I don't think it liked one of the html markup characters or the hyphen -.

     Resolved.
