Event logs are stored in files. These files have a default maximum size, which you can change. You can perform this procedure by using the Windows interface or a command line.
|
To set maximum log size by using the Windows interface |
-
Start Event Viewer.
-
In the console tree, navigate to and select the event log you want to manage.
-
On the Action menu, click Properties.
-
In Maximum log size (KB), use the spinner control to set the value you want and click OK.
|
Note |
|
Log size must be a multiple of 64KB and cannot be smaller than 1024KB. If you type a log size rather than use the spinner control, it will be rounded to the nearest multiple of 64KB. |
|
|
To set maximum log size by using a command line |
-
To open a command prompt, click Start, click Run, type cmd, and click OK.
-
Type the following command:
wevtutil sl <LogName> /ms:<MaxSizeInBytes>
To view the complete syntax for this command, type the following at a command prompt:
wevtutil sl -?
Additional considerations
- You must be a member of the Administrators
group to set a maximum log size.
- If you set a maximum log size that is smaller
than the current size of the log, the maximum size will not be
enforced until after the log is cleared.
