vmware的vcenter 6.0日志目录随着时间增加越来越大，参照vmkb的说明，设置日志自动旋转(logrotate)，对于节省VSA空间有很大作用
参照文档：
https://kb.vmware.com/s/article/2147261
https://communities.vmware.com/t5/VMware-vCenter-Discussions/Delete-the-cloudvm-ram-size-log/m-p/456386?tstart=0
新增两个文件
vi /etc/logrotate.d/cloudvm_ram_size.log
/storage/log/vmware/cloudvm/cloudvm-ram-size.log{ missingok notifempty compress size 20k monthly rotate 5 create 0660 root cis }
vi /etc/logrotate.d/vmware-sso
/storage/log/vmware/sso/localhost_access_log.*.txt{ missingok notifempty compress size 20k monthly rotate 5 create 0660 root cis }
然后执行进行更新：
logrotate -f /etc/logrotate.conf
