The regex is not part of an ifconfig command, it's what part of the code is using to parse / process the client data report.

ifconfig doesn't accept regular expressions as input (well, mine doesn't
anyway). Try running it manually. You'll probably need to pre-parse the
interface(s).

Yep, in /usr/lib/xymon/client/bin/xymonclient-linux.sh I have:
---
# Bug in RedHat's netstat spews annoying error messages.
netstat -ant 2>/dev/null
echo "[ifstat]"
/sbin/ifconfig lo
/sbin/ifconfig bond2
/sbin/ifconfig rhevm
# Report mdstat data if it exists
---
However there is no rhevm interface listed on the trending page.

What shows up under 'Client data available' for the [ifconfig] and
[ifstat]
details? [ifconfig] should list all of the interfaces. [ifstat]
should only
show what you defined.
The only interfaces I want graphed are "rhevm" and "bond2".
That would be:
echo "[ifstat]"
/sbin/ifconfig rhevm
/sbin/ifconfig bond2
[ifstat] should show the output from the above commands, which
should then
be on the trends page under Network Traffic.
I'll be taking a look at 4.3.2 sometime in the near future, maybe
it's
different there.

Yeah, that's pretty much what I did, except I now notice that the
bridge interfaces are not listed on the trending page. One of
these
bridge interfaces has an IP address and I'd like to trend it.
I've done a few quick greps through the source but can't see where
these bridges a re being stripped out.

Colin,
I have not installed any of the newer xymon versions, this is from
4.2.0.
On a system with eth0->eth3 plumbed up I set the client shell
script
(client/bin/hobbitclient-linux.sh) to:
echo "[ifstat]"
/sbin/ifconfig eth0
/sbin/ifconfig eth2
Verified the data sent from one of the 'Client data available' data
sets.
Removed the rrd files for ifstat from the server for that client.
(stopped/started the client).
On the trends page I see eth0 and eth2 only, no eth1 or eth3.
Yeah, it's a hack but it's fairly minor and should be easy enough
to manage.
Just my 3 cents.

Hi Vernon and Tim
I'm working in a new dev/test environment using Xymon 4.3.2.
I'd wanted to avoid hacking the client-side script but if that's
whats
required, I'll have a look.
TIA

If you are talking about the trends/"Network Traffic" graph it
seems to be
getting that data from the 'ifstat' var.
Some details follow.
1. what we graph for ifstat
hobbitgraph.cfg: FNPATTERN ifstat.(.+).rrd
See data/rrd/$hostname/ifstat.*
2. where ifstat originates
client/hobbitclient-linux.sh:
echo "[ifstat]"
/sbin/ifconfig
3. what happens to ifstat
hobbitd/client/linux.c: ifstatstr = getdata("ifstat");
hobbitd/client/linux.c: unix_ifstat_report(hostname, clienttype,
os, hinfo,
fromline, timestr, ifstatstr); <--- ifstatstr
You should be able to modify the client shell script to report
other than
ifconfig -a (which seems to be what is currently captured). Of
course, there
must be a better way.

Tim

Anyone have any thoughts on this?
