Change SCCM Server log file size using Configuration Manager Service Manager

In this post I will be showing how to change SCCM Server log file size using Configuration Manager Service Manager. Configuration Manager server side log files for Site servers are located under installation directory of Microsoft Configuration Manager\logs folders. If installation was done in d drive, then the location would be d:\Program Files\Microsoft Configuration Manager\Logs.

Configuration Manager creates log files for each specific component, let say mpcontrol.log which shows the health of the Management point has a component name called “SMS_MP_CONTROL_MANAGER” and each log file is assigned a specific log file size.

In case, more data is captured, it will become historical log file so as to start capturing the latest logs. Mpcontrol.log size if exceeds 2 MB, it will now have 2 files:

• Mpcontrol.lo_ (historical log file – old one)
• Mpcontrol.log (latest one)

Requirement for increasing the log file size

But what if you were not able to capture all the details as log file of 2 MB looks pretty small and if you wanted to get the data 3-4 days old, and found it has been overwritten ?

This is where increasing the log file size will be useful to capture more data. Rather than specifying 2 MB, we can make it 10 MB or anything what we like.

Majority of Configuration Manager components / log files are having 2 MB log file while few of them are having different size. We can change the value for each specific component based upon our requirement.

How to increase SCCM Server log files size

SCCM Site Server log files size is saved under the registry key Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SMS\Tracing, where we can see list of all Site Server components.

For CONFIGURATION_MANAGER_UPDATE component, we can see maximum file size and log file name with location:

MaxFileSize is 15728640 (15 MB)

TraceFilename: d:\Program Files\Microsoft Configuration Manager\LOGS\CMUpdate.log

We can change the value here.

However, I would prefer much more professional and efficient way to change this using Configuration Manager console.

Launch Configuration console and navigate to \Monitoring\Overview\System Status\Component Status to display list of all Component Status.

Right click any component, start and click Configuration Manager Service Manager.

Once Configuration Manager Service Manager is launched, you can see list of Configuration Manager Site Servers, expand it to see Components and Servers.

Under Components, select any specific component, for example SMS_EXECUTIVE, on right pane select the component and right click to select Logging.

Which comes up with “Logging Enabled” along with:

• Long filename: D:\Program Files\Microsoft Configuration Manager\Logs\smsexec.log
• Log size (MB): 2

Make appropriate changes for log size and that’s it.
