The CLIENT tag is used to tell the Xymon server how the incoming client
data will be tagged. You use this when your Xymon agent and the Xymon
server do not agree on which name to use -- usually because one of the
entries has FQDN and the other does not. This is the "cheap fix" for
"ghost" clients -- see the ghost report.
That's what I figured. On Solaris, it seems I run into this on all of
the hosts. uname -n always seems to return a short name. In fact, it
does not appear as if Solaris has much of a concept of a domain name,
and I can't figure if I'm supposed to keep the full name as the hostname
or not. Hasn't seemed to matter.
Some of the columns you are talking about (bbgen, hobbitd, etc.) are
implicit tests that are run no matter what on the Xymon server. Xymon
inherits a lot of the BB communications architecture but extends it in
many ways. The BBDISPLAY machine(s) will have "bbgen" tests -- this is
what creates the Web pages. The Xymon server will have the "hobbitd"
test -- this is what processes incoming data from Xymon clients. BBNET
machines will have the "bbtest" column -- this shows how network tests
are working.
They were missing, but apparently what happened is that at least the
"bbgen" tests were going into the bit running with a misspelled name, so
at least I know what is going on with them now. I guess these are
"client" tests on a Xymon server.
On a simple environment (the only kind I know) you will have all three
of these on your Xymon server and not on anything else. My *guess* is
that if you know how to break up BBDISPLY and BBNET you might see
different tests associated with each host.
Apparently not, and in my opinion, this is somewhat broken, unless I'm
misconfiguring something. Xymon appears to only have one notion of a
"server." If you're running a network test machine, it asks you for your
server name (example pasted):
BBSERVERHOSTNAME="xymon.umdnj.edu" # The hostname of your
server
BBSERVERIP="130.219.34.102" # The IP-address of your
server. Use the real one, not 127.0.0.1 .
BBSERVEROS="sunos" # The operating system of your
server. linux,freebsd,solaris,hpux,aix,osf
The "bbtest" test, with a solely "BBNET" machine configured this way,
appears as if it comes from the "BBNET" machine (status message received
from IP is the "BBNET" machine), but the test shows up under whatever
server name is defined in those above variables in hobbitserver.cfg. If
you set that server name to the name of the BBNET machine, as I expected
I was supposed to do initially, you get "connection refused" errors, as
it tries to connect to itself and cannot as it's not running the server
component that listens on the port.
I'm starting to believe that while you CAN separate the BBNET and
BBDISPLAY nodes with Xymon, no one is really doing it and it doesn't
work that cleanly. I'm not sure if this is what is happening, but since
I have two BBNET machines, I'd expect them to be writing over each
other's information as far as bbtest "on the display machine" is concerned.
One *fundamental* difference between Xymon and BB is that clients
collect data and send it to the server for analysis instead of simply
sending status messages. This allows the Xymon server to use
centralized thresholds -- makes it much easier to handle a distributed
environment because the definitions for "red", "yellow" and "green" are
all in one place. But you probably already know this!
Getting there! Thanks for the help.

BBDISP must be "0.0.0.0".

For bbclients (I have no experience with them myself) you simply
switch from the old to the new address.

Yeah, I took a look at that before writing. There's nothing

I can see that refers to anything like that. Only think I can
think of
is that the client piece may not be using the same hostname as my
machine. I don't know what xymon does in cases where one is
using FQDN
and one isn't. My bb-hosts line is:
130.219.34.102 xymon.umdnj.edu <http://xymon.umdnj.edu/>; #
BBDISPLAY bbd ssh !telnet !ftp
So I'm only missing some extraneous stuff, if I compare it to their
line. I don't think the CLIENT piece is strictly required. I guess I
will re-read the man page for bb-hosts.

With it's bb-host here:

I think that answers your question. Let me know if otherwise.

One, possibly last, question:
In the process of migrating my bb-hosts file from BigBrother to
xymon
and duplicating my current BB setup, it appears as if I managed
to lose
the tests for bbgen, bbtest, hobbitd... maybe another as well.
I can't
figure out what it is that causes these tests to show up, as I
do not
believe they were spelled out in the default bb-hosts file. Can
anyone
point me to either some good docs on that or an answer?
Currently, on the "BBDISPLAY" machine I have bbnet and bbretest
disabled. However, stats for these processes do not show up on the
"BBNET" machines either (sorry to use BB terminology but it
does not
appear that xymon has any term to make the description easy).
The BBNET
machines have hobbitd, bbhistory, bbpage, rrdstatus, rrddata,
clientdata, and bbdisplay disabled.
Thanks for any help!

If you have RRDtool installed, use the "--rrdinclude DIR" and
"--rrdlib DIR"
options to configure to specify where they are.
I guess no big deal.

From memory..few years of dust on that...
After you do a ./configure.server it will ask about RRDtool if it
can't
be found - I would imagine if you just leave it blank it would
skip over
the RRDtool parts. Also, like you said, ./configure.server
--help may
answer that better.

When you say "machines" you're saying it plural - you'll only
have to
install it on the bbdisplay (what server you query for WWW
pages). If
you don't want rrdtool you won't have graphs - when you do the
configure
just say you don't have rrdtool. The bbproxy/net machines
have no
need
for rrdtool. Graphs aren't crucial but they can most certainly
help in
several cases.
Yes, I have two network test machines that do not run the
display --
these were that I was talking about. I already have rrdtool
on the
display machine and the graphs work. I did not know there was a
way to
say that I don't have rrdtool. I'll look through configure, I
suppose,
but I didn't see anything like "--without-rrdtool" as is often
present
in other software.
I know some people have issues using NET: but you might want
to read
through the archives. From my understanding, it is by host not
test as
well.
Thanks, I'll hunt around.
Lastly, is there any concept of escalation in xymon as there is
in BB? I
wouldn't necessarily miss it, but I do currently use it.
(Escalation is
that no one can acknowledge a page in such a way that will
keep it
from
reaching the escalated party, except that person).
Maybe look at the critical list of hosts -

Good afternoon,
I am new to this list and probably will be new to xymon
shortly. I
have
currently installed it and am testing it out.
My current BB system consists of a BBDISPLAY machine, and
two BBNET
machines. The two BBNET machines are on either sides of a
firewall and
are housed on two different Solaris 10 zones.
I /think/ I know how to set this up, but there are some aspects
of it
that look like they might be irritating if there's no good
answer
for them:
First off, my BBDISPLAY does no network monitoring. This
looks as
simple
as setting DISABLE on the appropriate part of
hobbitlaunch.cfg, so
this
seems pretty easy.
Next, my network machines. I don't really want to have to
install
RRDTool on it. Is that really necessary? Isn't it only used for
