Best practices for reporting issues
To help you quickly identify and resolve errors, please try to follow the guidelines below:
- Provide a detailed description of the issue; this will help us understand your problem.
- When possible, make screenshots of all the steps you followed. The idea is to be able to reproduce the error or at least better understand the context in which it occurred.
- Videos are also welcome.
- Share the stack trace from the openkm.log file.
Because the support website has restrictions on document size, share with us a download link using online file-sharing tools such as:
Getting the stack trace
Linux
The openkm.log file is in the $TOMCAT/logs folder. For example, in Linux, a common location might be "/home/openkm/tomcat-9.0.76/logs".
To watch how openkm.log changes in real time, you can use the command line:
/home/openkm/tomcat-9.0.76/logs:$ tail -f openkm.log
To show the last 500 lines of the openkm.log file, you can use the command line:
/home/openkm/tomcat-9.0.76/logs:$ tail -n 500 openkm.log
Windows
The openkm.log file is in the $TOMCAT/logs folder. For example, in Windows a common location might be "c:\tomcat-9.0.76\logs".
To watch how openkm.log changes in real time, you can use a Windows tool like mtail.
You have a copy of the mtail tool in c:\tomcat-9.0.76\extras\.
Sample of stack trace capture
When you capture the stack trace, it is a good practice to include some extra lines before and after the error.
