Thank you so much Brent. That explains it. I reran the query and they all returned “NOTHING” now.

Lynn – that means there’s data in the transaction log that needs to be backed up. The log file might be a little on the small side.

Thanks Brent. I ran the above query and most of my databases returned “NOTHING” except two of them showed “LOG_BACKUP” in the log_reuse-wait_desc column. I just don’t know why since their log files are being backup every two hours. Any thoughts? Thanks.

I wish I had enough time to do this type of monitoring at work. Unfortunately, I end up with multiple hats many times and we don’t allot enough time for this type of work. I love being proactive, I’ll just keep pushing and hopefully things will change.

Oh yeah, nice post and hilarious. One of my new worst fears now is dropping that bar of soap.

Ha! I encountered the exact same issue only a couple months back. A 2GB database, regular log file backups and 90GB odd log file!

The customer had changed or removed mirroring from the database a long time ago, but the database was still in a state that it thought it needed to keep them around.

Looking forward to hearing your session at Red Gate SQL in the City [Seattle] in November.

Thanks Brent
What centralize monitoring solution have you been impressed with, if cost is not a road block?
