You can create a SQL Agent alert on the appropriate error message. You'll still have the effects of a full log on the DB though.

Why is your log filling often enough for this to be a concern?

This will alert you when the log usage gets to a certain %, this % amount is up to you.

CREATE procedure sqllogalert

@database varchar (20),

@threshold int

as

if not exists (select name from sys.databases where name = @database)

begin

print 'Database Does not Exist'

return

end

declare @server varchar(20)

declare @msgtext varchar (200)

declare @profile varchar (10)

set @server = @@servername

set @msgtext = 'SQL ALERT: Database '''+@database+''' On Server: '+@server+' - Transaction Log Usage Above Threshold'

set @profile = 'insert mail profile here'

if exists

(SELECT instance_name as [Database],

cntr_value as "LogFullPct"

FROM sys.dm_os_performance_counters

WHERE counter_name LIKE 'Percent Log Used%'

AND instance_name not in ('_Total', 'mssqlsystemresource')

AND instance_name = @database

and cntr_value > @threshold)

begin

exec msdb.dbo.sp_send_dbmail

@profile_name = @profile,

@recipients = 'insert recipients here',

@subject = @msgtext

end

else

begin

print 'Log File Ok'

end

Execute the procedure like this:

exec sqllogalert

@database = 'database_name'

,@threshold = threshold

Schedule it for as often as necessary

Thanks a lot for sharing this script.is there option to consider disk space as well since my production log file growing because of full recovery mode.

A properly maintained log should not be growing.

As Gail pointed out, your log should not be growing. Proper sizing and regular log backups are vital.

Have a read through the link she posted.

If you need to monitor disk space you could look at xp_fixeddrives or sys.dm_os_volume_stats (2008 R2 and above).

Thanks a lot for your reply.we have implemented regular log backup and restricted that issue now.

Still we want to avoid log full situation if backup log is not working .Here My production database is running on 2005 version.is there any alternative way for this.

I would recommend you set up an alert for when log backups are not working. Something that checks when the last log backup was and alerts you if it's more than a certain time ago.

My focus would be to make sure that log backups are running.
