Shows information on the total number of log files in all databases on this SQL Server.

The disk icon will “fill up” as the total percentage of all log files in all databases increases.

This is the current Log Used space in all log files as a percentage of the current size of all log files.

Note that the all figures in the disk icons are accumulated over all databases so that a Percentage Used figure of around 0% does not necessarily mean that all logs have plenty of space left. Also, some files may be configured to AutoGrow, so if this figure is approaching 100% it does not necessarily mean you are almost out of space.

The Fixed Log File Used or the Databases - Dynamic Log File Growths Remaining alarm is raised when any database is running out of log space.
