Problem with monitor OpenVPN or PPP on Remote Linux Server's

[andrey_a]

Hello.
There is a small question.
At me CACTI removes statistics on the removed host on SNMP from interfaces OpenVPN.
And here right at the beginning schedules are under construction normally, but it is necessary to restart server, and the interface accepts another an index in SNMP. And accordingly the statistics does not go.
How it is possible to remove statistics from such interfaces?

Is available in view of not only OpenVPN, together with ppp interfaces.

p.s.: I am sorry for my bad English. I read well, and I write badly. It not native my language.
