Logging must be started as soon as possible when a service starts and when a service is stopped. Many forms of suspicious actions can be detected by analyzing logs for unexpected service starts and stops. Also, by starting to log immediately after a service starts, it becomes more difficult for suspicious activity to go unlogged. On the vCenter Server Appliance (VCSA), the "vmware-vmon" service starts up the Java virtual machines (JVMs) for various vCenter processes, including vSphere UI, and the individual json configuration files control the early JVM logging. Ensuring these json files are configured correctly enables early Java "stdout" and "stderr" logging. Satisfies: SRG-APP-000089-WSR-000047, SRG-APP-000092-WSR-000055

Check Text ( C-60458r889346_chk )
At the command prompt, run the following command:

# grep StreamRedirectFile /etc/vmware/vmware-vmon/svcCfgfiles/vsphere-ui.json

Expected result:

"StreamRedirectFile": "%VMWARE_LOG_DIR%/vmware/vsphere-ui/logs/vsphere-ui-runtime.log",

If no log file is specified for the "StreamRedirectFile" setting, this is a finding.
