Increase logging level for VirtualCenter vpxd manually

Step 1: Log into vCenter Server as administrator.

Step 2: Open configuration file for vpxd (vpxd.cfg) in text editor.
%ALLUSERSPROFILE%\Application Data\VMware\VMware VirtualCenter\vpxd.cfg
vCenter Server Appliance: /etc/vmware-vpx/vpxd.cfg
Windows 2008: C:\ProgramData\VMware\VMware VirtualCenter\vpxd.cfg
vCenter Server 6.0: C:\ProgramData\VMware\vCenterServer\cfg\vmware-vpx\vpxd.cfg

Step 3: Change info to trivia.

Step 4: Increase <maxFileSize> parameter to change maximum size of the logs.

Step 5: Increase <maxFileNum> parameter to change maximum number of logs.
