Trending too many interfaces - see regex
Colin,
I've not had the time, desire or opportunity to play with any of the newish RedHat releases and associated gizmos. This said, I accept that your 'ifconfig rhevm' returns data in the same format as 'ifconfig eth0'.
Most linux interface names end with some number, or are called 'lo'. 'rhevm' does not seem to follow that norm. I suspect trending of rhevm might be failing for this reason.
In xymon-4.3.2/xymond/rrd/do_ifstat.c on line 22 we see the following regex: ^([a-z]+[0123456789.:]+|lo)
Remove the localhost part and it looks like this: ^([a-z]+[0123456789.:]+)
Expand that and we have: ^rhevm+[0-9.:]+
To me, that looks like rhevm by itself is not a match. Folks who actually write the code / have a clue about GNU C regex / can probably address this better than I.
Regards,
Tim

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.

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.

If you are talking about the trends/"Network Traffic" graph it seems to be getting that data from the 'ifstat' var.
Some details follow.
what we graph for ifstat hobbitgraph.cfg: FNPATTERN ifstat.(.+).rrd See data/rrd/$hostname/ifstat.*
where ifstat originates client/hobbitclient-linux.sh: echo "[ifstat]" /sbin/ifconfig
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.

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).

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.

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

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

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.
Regards,
Tim

Anyone have any thoughts on this?
The only interfaces I want graphed are "rhevm" and "bond2".
