The easiest way to obtain the log files is to log into the dashboard as the Master Admin user.
Amend the URL in the browser by removing the content after /pi and adding /log e.g. http://localhost:8224/pi/log or https://dashboardurl:port/pi/log
This will allow you to download all files as a zip file or grab the one/ones you need.
They can also be found in the following locations (depending on the deployment method)
‘Installation location’\Dashboard\tomcat\logs
Windows
C:\Program Files\Dashboard\Dashboard\tomcat\logs
C:\Program Files\Dashboard\Dashboard\Renderer\logs
C:\Program Files\Dashboard\Dashboard\Scheduler\logs
C:\Program Files\Dashboard\Dashboard\ExcelReader\logs
Linux
/opt/panintelligence/Dashboard/tomcat/logs
/opt/Panintelligence/Dashboard/Renderer/Logs
/opt/Panintelligence/Dashboard/Scheduler/Logs
/opt/Panintelligence/Dashboard/ExcelReader/Logs
AWS – (unless you specified another location in your env variables, under volumes).
i.e./var/panintelligence/Dashboard/tomcat/logs or via the management console.
The most useful logs to investigate (depending on the error) are:
Stacktrace
Scheduler (both in the tomcat/logs and Scheduler/logs)
Pi-renderer (both in the tomcat/logs and Renderer/logs)
Excel-Reader (both in the tomcat/logs and ExcelReader/logs)
Any/all Catalina
Dashboard_tomcat_stderr
Dashboard_tomcat_stdout
