Hello everyone,

I'm working on getting one of my Amanda servers to finish dumping a
little bit faster.  Right now, all but one of my hosts are taking
around four hours to finish.

Anyhow, I noticed that amstatus says this after the run:

 0 dumpers busy :  0:33:39  (  3.64%)            not-idle:  0:33:39 (100.00%)
 1 dumper busy  :  9:38:18  ( 62.47%)            not-idle:  9:37:29  ( 99.86%)
                                             no-bandwidth:  0:00:49  ( 0.14%)
 2 dumpers busy :  0:28:11  (  3.05%)            not-idle:  0:27:57  ( 99.18%)
                                             no-bandwidth:  0:00:13  ( 0.82%)
 3 dumpers busy :  0:26:59  (  2.92%)        no-bandwidth:  0:22:59  ( 85.20%)
                                                 not-idle:  0:03:59  ( 14.80%)
 4 dumpers busy :  2:13:20  ( 14.40%)        no-bandwidth:  1:56:04  ( 87.06%)
                                                 not-idle:  0:17:15  ( 12.94%)
 5 dumpers busy :  1:12:40  (  7.85%)        no-bandwidth:  1:12:40 (100.00%)
 6 dumpers busy :  0:32:23  (  3.50%)        no-bandwidth:  0:32:23 (100.00%)
 7 dumpers busy :  0:03:03  (  0.33%)        no-bandwidth:  0:03:03 (100.00%)
 8 dumpers busy :  0:00:27  (  0.05%)        no-bandwidth:  0:00:27 (100.00%)
 9 dumpers busy :  0:00:48  (  0.09%)        no-bandwidth:  0:00:48 (100.00%)
10 dumpers busy :  0:00:09  (  0.02%)        no-bandwidth:  0:00:09 (100.00%)

Looks like I have too many dumpers for my bandwidth, no?  FWIW,
netusage is set to 80 Mbps.


But amplot's Bandwidth Allocated graph shows the line mostly pegged at 0% the
entire time.  From glancing through the amplot scripts, I'm guessing
this should be labeled "Bandwidth Free"?
