asp.net 2.0 health monitoring, aspnet_webevent _events.details truncated

[hui]

I am trying to use an SQL Server 2000 to log the events, and have found
somehow the contents in the details column get truncated. Details as
following:

The query I am using to retrieve details:
select datalength(deta ils), details from dbo.aspnet_WebE vent_Events

A sample output row (slightly realigned for easy reading):
1842 Event code: 4003
Event message: URL authorization succeeded for the
request.
Event time: 3/13/2006 11:38:28 AM
Event time (UTC): 3/13/2006 12:38:28 AM
Event ID: a2b76c4f41354e1 68ad7d174abbc7f 90
Event sequence: 7
Event occurrence: 4
Event detail code: 0

Ap
-----------------------------------------------------------------------------------------------------------
None of the values exceeds 9XX characters ( or 18xx bytes as it s ntext
column).

Here is the web.config I am using:

<healthMonitori ng enabled="true" heartbeatInterv al="100" >
<providers>
<add connectionStrin gName="MyDB"
maxEventDetails Length="1073741 823"
name="Customeri zedProvider" buffer="true"
bufferMode="Not ification"
type="System.We b.Management.Sq lWebEventProvid er,

System.Web,Vers ion=2.0.0.0,Cul ture=neutral,Pu blicKeyToken=b0 3f5f7f11d50a3a"

maxEventDetailL ength="Infinite "/>
</providers>
<rules>
<add name="Standard Web Requests"
eventName="All Events"
provider="Custo merizedProvider "/>
</rules>
</healthMonitorin g>

As a new bee to this health monitoring feature, I don't have much clue
on what's going on there.

Could anybody give me some hints?
