[ns] Queue Monitoring

["Thomas Kuborn" <thomas@kuborn.be>]

Morning,

Page 73 of the NS manual, I spotted a couple variables i could query
regarding queue state so i wrote this little piece of code :

$ns monitor-queue $n2 $n3 size_ pkts_ barrivals_ bdepartures_ parrivals_
pdepartures_ bdrops_ pdrops_ bytesInt_ pktsInt_

which generated an error

The following 2 lines didnt generate any error :

$ns monitor-queue $n2 $n3 size_ pkts_
OR
$ns monitor-queue $n2 $n3 barrivals_ bdepartures_

It appears I can only monitor 2 variables at the same time ... Did i do
something wrong or is that a limitation in NS ?


Now i've managed to set up a queue monitoring object ... but how do i get
values of the variables ?

Should i retrieve those values in the same way its done for LossMonitor ?
like this
set lost0 [$sink0 set nlost_] ?


Please help me i'm clueless

Thomas
