Monitoring cluster SQL Server

Hi,

I have 2 SQL Servers in a cluster.
I need to monitor both the servers in a cluter to find which is up and which is down.
so whenever I do a failover it has to show the first server SQL01 is down-View1 SQL query
I have to do the same thing when the second server down,  has to show SQL02 is down-view2 SQL query.

we have got our own inhouse monitor application running on asp.net which can pass the SQL view as a parameter with relevant columns
for monitoring purposes.

I need to crate 2 views like this(at least this is the logic)
CREATE VIEW dbo.SQL01
declare @var1 as varchar(30)
set @var1 = cast(serverproperty('ComputerNamePhysicalNetBIOS') as varchar)
if
@var1<>'SQL01'(when it is not SQL01,I know that it has been failed over to SQL02)


thanks

We wanted to use our monitoring.aspx program.
It is not a problem for us to get the alerts using our own system.
But in this case the first time I have to use serverproperty function to get some results.
I don't know how to create conditional VIEW's for system functions like this "SERVERPROPERTY"

I have created another VIEW only for finding the cluster server name using,

CREATE VIEW dbo.ClusterName
(ServerName) as select serverproperty('ComputerNamePhysicalNetBIOS')

and when I pass "ServerName" as the field input-I get the active cluster name.

But my problem is how I will write conditions in a view especially for "SERVERPROPERTY" function to find out

New View1 SQL01- condition if Servername <> SQL01 -----(so whenever we fail over, this monitor should goes down as it is not SQL01)
output as SQL02.

New View2 SQL02- condition if ServerName <>SQL02---(same here.)
output as SQL01.

thanks

I just found out the solution myself.


CREATE VIEW [dbo].[Server1]
 (Server1)as SELECT cast(serverproperty('ComputerNamePhysicalNetBIOS') as varchar(50))
                   where cast(serverproperty('ComputerNamePhysicalNetBIOS') as varchar(50)) !='SQL01'


Now I can call this view to trigger the monitor page to stay up or down.
if the value is not 'SQL01' in the Server1(field) the monitor goes down.

thanks
