    Something has changed and you need to find out what has changed;
regardless, every minute is not really necessary unless you have some
mission critical reason to snapshot the SNMP every minute. If you haven't
modified the Web pages you will notice that it updated every 5 minutes.

    Every where I have installed this I have always left the default 5
minutes. I one set it less then 5 minutes if my client had a mission
critical circuit and then I trapped it out if it reached a threshold for
more then 5 minutes.  Mission Critical too me is a circuit that would cost
the company a great deal of money if it's bandwidth was max'd.

    One of the best commercial packages for Bandwidth Monitoring and
Trending is Concords eHealth and they recommend no less then 5 minutes
unless it's a mission critical circuit. Even then Concord says keep it at 5
minutes unless there are potential issues.

    If you insist on less then 5 minutes either break up the config into
small parts or try polling every two minutes.
