I am looking for a program that will give me the top user on a wan link and be able to send the results to rdd?
Any one see anything like this? I have seen ourmon but I believe it will only work on freebsd.

Subject: [rrd-users] Cricket/RRD fetch resolution problem (2nd try)

I am running RRDTool 1.0.33 within Cricket-1.0.2 and have a problem with the
resolution of data that I pull out via RRD:fetch (either through the Perl
Module or through the command line rrdtool).

The issue is that I have my RRDs set up like this (via the cricket config
file)

     # one point per 5 minutes, spanning 50 hours
     rra             5minAve     AVERAGE:0.5:1:600
     # one point per 5 minutes, spanning 366 days
     rra             5minUse     AVERAGE:0.5:1:105500
     # one point per 30 minutes, spanning 12 days
     rra             30minAve        AVERAGE:0.5:6:600
     # one point every 2 hours, spanning 50 days
     rra             2hrAve          AVERAGE:0.5:24:600
     # one point every day, spanning 600 days
     rra             1dayAve         AVERAGE:0.5:288:600

     # we will add datasources to each specific target-type later
     targetType      --default--
             rra     =       "5minAve, 30minAve, 2hrAve, 1dayAve,
     5minUse"

And when I do a query for "-s "now-1month" I should pull 8930 values from the
"5minUse" RRA, but sometimes I pull 374 values which seem to come from the
"2hrAve" RRA instead of the  "5minUse" RRA. Now, I have some RRDs no longer
being updated, due to the switch not being used anymore, and the data is
historical, but still valid, and the problem doesn't seem to be related to the
last updated field.

Here's a short example.

     # ls -la data1.rrd
     -rw-r--r--   1 usage    5000     1728368 Jul 23 11:00 data1.rrd
     # ls -la data2.rrd
     -rw-r--r--   1 usage    5000     1728368 Aug  1 19:40 data2.rrd
     # rrdtool fetch data1.rrd AVERAGE -s now-1month > /tmp/ck1
     # rrdtool fetch data2.rrd AVERAGE -s now-1month > /tmp/ck2
     # ls -la /tmp/ck*

So, is this a resolution problem? Is RRD looking at the last update and
deciding that this data is too old, or what?
