disk space full alert

How do I setup alert for the disk space full warning?
For example, I want to throw an alert when 80% of c:\ is used ... so that
some clean up operation can happen ...
Please give detailed answer to this ...

Hi
This one i have just found on internet
/*
This procedure will send a notification if the free disk space on any of the
drives
SQL Server resides on is lower than the specified limit.
The alert can either be an email or netsend.
usage: exec master.dbo.sp_diskalert 'harry@.foo.com', 1000
Will send an email to harry@.foo.com if the free disk space is less than
1000mb
NB more than one email address can be specified, separate using semi colons
USAGE: EXEC master.dbo.sp_diskalert 'HARRY PARKINSON', 250
Will send the alert via net send to user harry parkinson if the free disk
space is less than 250mb
NB this could also be a computer name, normal net send rules apply
Supports sql server 7 or 2000
You need sql mail configured to send email!
If xp_cmdshell doesn't exist it will be added and dropped as needed

|||Even though Uri's solution will work, it might be better to look for a
monitoring tool that can monitor your diskusage, free space etc. rather than
trying to tweak SQL server to do it. I'd also think that you have the risk
that if the drive run out of space, SQL server stops and then you'll never
get the email.

|||Krishnaprasad,
If you have the budget, I would recommend evaluating a few enterprise
monitoring solutions as they will tend to be more robust, and
configurable. However, they tend to be very expensive.
If you want something quick and dirty, you can either write a VBScript
and use the FileSystemObject to check drives on a server - parameterise
this so you can pass in a server name, and possibly even a drive letter.
Also, take a look at xp_fixeddrives stored procedure for a T-SQL based
solution. You could poll this every day in a SQLAgent job, and log to a
table so you can plot a trend.

|||Hi Uri,
Thanx a lot for the solution. It works for me on my local machine. I get the
mail in my mailbox.
Now when I exec the same proc on a different SQL server on the same network,
giving same parameters, it fails for xp_sendmail.
I get the error - xp_sendmail: Procedure expects parameter @.user, which was
not supplied.
I serached using BOL, xp_sendmail does not take @.user parameter, it takes
@.Set_user. But setting this parameter does not solve the problem.
What is wong in this? Please advice.
regards
KP
