Hi,
Is it that your not able to open it or is it that there is no data being displayed.
Jusy clarifing by you meanin you copied "sepm_monitor.jar" and "SepmMonitorTool.bat" into the SEPM installation folder and then tools? if not please copy it then run it from there for more data to be displayed follow the steps below
Steps to enable Apache Logs on each SEPM server:
1)Access SEPM_INSTALL\apache\conf folder and take backup of httpd.conf file
2)In httpd.conf file, enable access and error logging. Also set LogLevel to info.
Error log: Uncomment #ErrorLog "|| bin/rotatelogs.exe logs/error-%Z.log 100M", change log file name format and log rotation to 24 hours.
Modified line: ErrorLog "|| bin/rotatelogs.exe logs/error-%Y-%m-%d.log 86400"
Access log: Uncomment #CustomLog "|| bin/rotatelogs.exe logs/access-%Z.log 100M" combined, change log file name format and log rotation to 24 hours.
Modified line: CustomLog "|| bin/rotatelogs.exe logs/access-%Y-%m-%d.log 86400" combined
LogLevel: Change LogLevel from warn to info.
Modified line: LogLevel info
3)Restart the Apache (net stop semwebsrv and net start semsrv)
