Hi all

I've several Linux (RHEV) virtualisation servers.  In the trends
screen for these servers, I see a list of interfaces similar to the
below:

Only two of these have IP addresses, how can I limit Xymon to just
showing the ones with IPs?

Thanks

Anyone have any thoughts on this?

The only interfaces I want graphed are "rhevm" and "bond2".

This is a crazy guess, you don't mention which version of xymon so this may be way off.  It may be way off anyway :)

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.

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

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.

Tim

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.

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.
