Re: netmon -a12

The 'behind' is for that interface only. After it does that interface, it
is
rescheduled with a future time. What I do is count the number
of records with negative numbers with a grep. That's the number of
interfaces it
is behind by.

Subject:  [NV-L] netmon -a12



Happy Friday, Y'all,

Here's a weekend puzzler. I am monitoring the netmon polling queue on my NV
6.0.1, Solaris 2.6 system to see how often and for how long the queue might
get backed up over the course of a day. There are 3181 interfaces in the
netmon -a12 output. The polling rates are a mixture of 1 min, 1 hour and 5
min (default) intervals. I have a simple script that deletes the
netmon.trace file, runs a new netmon -a12 and then appends the first line
of
that output to a file. The script runs every minute. Here's a sample of
that
output.

Note the entries that indicate the queue is behind by several thousand
seconds. Then the next minute the queue is essentially caught up. Anyone
have an idea what this means, or if it's a known
'anomaly', why the system does this?
