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.)
