Jamf Server logs issue on windows server

Yes - broken here as well and on multiple servers. Logs are being written to C:\\Program Files\\JSS\\Logs\\Library\\JSS\\Logs. I have a support case open with Jamf. It seems they messed up the log4j2.xml file. The loggingDirectory property is wrong and possibly the paths to the actual log files as well.

I do have a support case open. I fixed mine the same way as you. They were going to verify they could replicate the issue and get engineering involved.

@cbrewerthanks for providing a fix.

Apparently the original file patterns were saved in the log4j.properties file.  Hopefully we do not lose log file changes on the next upgrade.

Below are the first few lines of log4j.properties file:

We have recently upgraded JAMF to version 10.48.2-t1689860131 and lost the server logs again.

My previous post was cryptic, so I will clarify what worked for us since we have JAMF installed on a Windows Server using drive F:\\ similar to OP @dhausman.

To get the logs to work again we modified the log4j2.xml file located here:
F:\\Program Files\\JSS\\Tomcat\\webapps\\ROOT\\WEB-INF\\classes

We changed the loggingDirectory property
from: <Property name="loggingDirectory">${sys:log.dir:-/Library/JSS/Logs/}</Property>
to: <Property name="loggingDirectory">F:/Program Files/JSS/Logs/</Property>

We also removed all references to C:\\Program Files\\JSS\\Logs\\ so RollingFile entries should look similar to this:
<RollingFile name="JAMF" fileName="${loggingDirectory}JAMFSoftwareServer.log" filePattern="${loggingDirectory}JAMFSoftwareServer${archiveExtensionDateAndInterval}">

Make sure you save your changes and restart Tomcat.

After installing 10.48.2 things seem to just work for me using the windows installer.  I don't have to mess around with the log4j2.xml file any more. The recent installers fixed things by auto feeding the install path into the log config.

I found that 10.48.0 and 10.48.2 Windows installers will keep your previous log4j2.xml if there is one. If you want it rewritten with a new/default one, you need to delete the file before running the upgrade. This almost seems like a bug, but I haven't opened a support case. Regardless, it does appear that Jamf is writing correct paths into the log4j2 file when it does create a new one now.

It sounds like you're experiencing issues with the Jamf Server logs not functioning properly, possibly due to the log4j2.xml file configuration in the recent updates. If you’re running a Windows server and using the D drive, you’re not alone in facing this challenge. Proper server management is crucial, and if you need additional support or solutions, consider reaching out to HostNoc for assistance with your server setup.
