    Some of my colleques complained once, that at full tilt
    the fiber-channel fabric overflowed its SNMP bitcounters
    every 2 seconds.

    "we need to do polling more rapidly, than the poller can do"

    The SNMP pollers do handle gracefully 32-bit unsigned overlow,
    they just need to get snapshots in increments a bit under 2G...
    (Hmm.. perhaps I remember that wrong, a bit under 4G should be ok.)
