I/O Analyzer 1.6.2 appliance doesn't generate reports.
Logs indicate:
unable to call charting scripts: Cannot run program "/bin/sh" (in directory "/root/ioAnalyzerScripts"): java.io.IOException: error=13, Permission denied.
ioAnalyzerScripts are in the /root directory which Tomcat cant get to.
As a workaround you can chmod 755 /root directory.
