Cacti EZ

If you are running a Cacti EZ 0.6 based on CentOS 4.x inside a Hyper V Virtual Machine you will see that the machines system time runs out of sync, but you have configured NTP correctly.

Symtoms:

  • If Cacti EZ runs for about one hour and you may see a time difference of ~90 seconds to your NTP time.
  • "ntpdate -u ntp.example.com" command shows you differences to the current time whenever you execute it.

Solution:
