So we're fighting the constant battle here about never enough space, no matter how much we buy, and the complaints we get back are "well, I don't see how we could be using that much space, who is using it?" which in itself is a relatively simply question to answer once by pulling a quota report, but what we're finding the need to do is have some automated process whereby managers can look at say a web page and see the current status of how much space is being used by whom. (We are, however, forbidden from actually enforcing quotas.)
I had hoped I might be able to pull individual user and tree quota reports from the filer via snmp, but I'm not having much luck with it, and what little I'm finding about it online is implying that the snmp quota implementation is not complete, but then those comments seem to be several years old. I had some thoughts of actually tracking certain specific problem users with cacti, keeping long term trend graphs of their space usage, but can't seem to actually get individual quota numbers from snmp.
So any suggestions out there about tools, scripts, whatever that can do this for us? A nicely formatted html page that anyone can access would be ideal.

It it possible, we're doing it.
BigBrother (www.bb4.org) has a contributed script (www.deadcat.net), which does it, and using BigBrothers graph-plugin we're also getting nice graphs.
But on to the relevant part of the script (written by Sean MacGuire - BB4 Technologies Inc.): ----------------------------------------------------------------------
# Are quotas enabled? quotaStateOn(2) set `$SNMPWALK $HOST $COMMUNITY quotaState.0` QUOTAS="$4" if test "$QUOTAS" = "quotaStateOn(2)" then
set `$SNMPWALK $HOST $COMMUNITY qrIndex | $TAIL -1` NUMPART="$4" LINE="NetApp has $NUMPART quota trees"
COUNT="1"
while test "$COUNT" -le "$NUMPART" do set `$SNMPGET $HOST $COMMUNITY qrPathName.${COUNT}` DFMOUNT=`eval echo $4` set `$SNMPGET $HOST $COMMUNITY qrKBytesLimit.${COUNT}` DFTTL="$4" if test "$DFTTL" -lt "0" then DFTTL=`expr $TWO32 + $DFTTL` fi set `$SNMPGET $HOST $COMMUNITY qrKBytesUsed.${COUNT}` DFUSED="$4" if test "$DFUSED" -lt "0" then DFUSED=`expr $TWO32 + $DFUSED` fi DFAVAIL=`expr $DFTTL - $DFUSED` DFPCT=`echo "100 * $DFUSED / $DFTTL" | bc` DFNAME="quota-$DFMOUNT"
echo "$DFNAME $DFTTL $DFUSED $DFAVAIL ${DFPCT}% $DFMOUNT" COUNT=`expr $COUNT + 1` done
fi ----------------------------------------------------------------------
You need to have the Netapp MIB and the MIBS environment variable set: $ MIBS=+NETWORK-APPLIANCE-MIB; export MIBS
I've had to make changes to script because the newest NetSNMP has changed it output, compared to older versions. Depending on the output you may have to change the $4 to $3.

BigBrother can do it, but it's not exactly plug'n'play. On our version of BB we have the following plugins:
http://www.deadcat.net/viewfile.php?fileid=885 http://www.deadcat.net/viewfile.php?fileid=82
Which then requires rrdtool, libgd, etc.
