Glen,

Not much in the way of help I know but I too am having similar problems.
I've compiled NeMaC version 4.1 under Digital Unix on alpha and am also
having the problem with no write access to the meter.  This is a consistent
problem on 2 486's, one with a 3com etherlink III and one with a 3com
3c509(f), tying to run the 32bit meter.

However, I have been able to get the 32bit meter to work on one 486 with a
3com (not sure which type) card in it.  This machine, however, is giving me
spurious results not in line with a separate installation of netramet I am
using.

The separate installation I have running that appears to work correctly is
using version 3.4 meters and version 3.4 NeMaC compiled under Ultrix 4.4 on
a DEC station 5000 (I think)

I've been able to get NeMaC 4.1 on the alpha to successfully manage a 3.4
meter and it is producing acceptable results.

One additional small problem I've had with the 4.1 installation is the
parser for the fd_filter and fd_extract format files is not reading the
first characters on the line.  For the moment I've just gotten around this
by putting an extra character at the start of each line.  (a full stop)

I realize this isn't particularly much help but maybe we can put the pieces
together and work out what's happening.  One small hitch is that I'm on
holidays for the next 2 weeks, but after that I'll be free to experiment.

Regards

David Sturgess.

I am running Netramet (on a Linux machine) on my network to monitor
network utilization and
have noticed that the CPU utilization to be in the very high ( >95% ). Is
this normal? If I were monitoring just a handful of hosts, won't this
make the CPU consumption a lot lower??

TIA

Subject: Problems with naming Logfile & Flowfiles (-L & -F) NeMaC options
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit
Sender: [email protected]
Precedence: bulk

Hi all,

I am running NeTraMet 4.1 on 13 remote monitoring hosts, and NeMaC on
one centralised host. The remote hosts are FreeBSD 2.2.2 & the central
host is a Sun Ultra2 running Solaris 2.6.

I was trying to use the '-p' option so log and flow files would
be 'appended' to if things were stopped/started; or created new
if they didn't exist. Also, I was using the '-L <log_file_name>'
and the '-F <flow_file_name>' options to name the files.

For testing I was collecting stats every 2 minutes (-c 120). Strange
things were happening with the collection of some of the stats from
some meters. Initially they would all start off collecting at two minute
intercals, but them some of them would start to collect only every 4
minutes.
(I was running a NeMaC separately for each meter.)

This started after NeMaC had collected only a few samples from the
respective
meters.

This only happens when I use the -L and/or the -F NeMaC options.

Has anyone seen this behavour?

It also happened on the 4.1B15 I was running too.

Thanks in advance,

Brian

P.S. A note for Nevil. In the NeTraMet & NeMaC doco, the NeMaC '-P'
option
says it is for use on the flows files, but in the source it says it is
for
the log file.

        case 'P':
           append_log++;  /* Only append to log file, not data file(s)
*/
           break;
