Question

当您右键单击数据库，报告...磁盘使用情况时，我会收到报告。因为我的权限有限，所以我只得到顶部，显示“事务日志空间使用” - 这个数字本身对我有用。

但是，稍后我收到有关无权运行DBCC showfilestats的错误消息，而且我也无法访问sys.dm_os_performance_counters或DBCC SQLPERF（'logspace'）。

如果我能得到那个最高号码，那将是有用的。不幸的是，我无法运行探查器，所以我不知道它发出什么命令或查询来获取数据...

我自己的SSMS磁盘使用情况报告的Profiler捕获显示DBCC SQLPERF(LOGSPACE)：

exec sp_executesql @stmt=N'begin try 
declare @tran_log_space_usage table( 
        database_name sysname
,       log_size_mb float
,       log_space_used float
,       status int
); 

insert into @tran_log_space_usage 
exec(''DBCC SQLPERF ( LOGSPACE )'') ; 

select 1 as l1
,       1 as l2
,       log_size_mb as LogSizeMB
,       cast( convert(float,log_space_used) as decimal(10,1)) as SpaceUsage
,       ''Used'' as UsageType 
from @tran_log_space_usage 
where database_name = DB_NAME() 
UNION 
select 1 as l1 
,       1 as l2
,       log_size_mb
,       cast(convert(float,(100-log_space_used)) as decimal(10,1)) as SpaceUsage
,       ''Unused'' as UsageType 
from @tran_log_space_usage 
where database_name = DB_NAME();  
end try 
begin catch 
select -100 as l1
,       ERROR_NUMBER() as l2
,       ERROR_SEVERITY() as LogSizeMB 
,       ERROR_STATE() as SpaceUsage 
,       ERROR_MESSAGE() as UsageType 
end catch',@params=N''

SSMS如何获取事务日志用法？
