Hi,
Do you have anything under Ghost reports on the
xymon server?
I don't have anything under ghost report.
Are the client and server on the same or
different hosts?
They are running on different hosts.
Is the client pointing at the correct address and
port for the xymon server
Yes it is pointing the correct address and port.
How do you know files are missing from
~/client/tmp directory .. what are you expecting to see
there?
When the client functioned(the test were green in xymon server) correctly i saw two more files there logfetch.clientname.cfg and logfetch.clientname.status.
Have you checked the clientlaunch.log and
xymonclient.log files for errors in ~/client/logs?
I see no errors.
Regards,
Traian.

RE: [Xymon] Ghost client problems
Hi,
That one i have solved it, but....
Now i have
reinstallled the client and i started it using ./runclient.sh
--hostname=host start command from xymon user.
On the xymon server
web page all the tests(disk,cpu etc) appear in violet colour and i see
there the last report i had from when it functioned ok.
On the client
i have issued some commands and you have the output
here:
[root at otpproxy1 tmp]# ps -ef | grep
xymon
xymon 3785

-rw-rw-r-- 1 xymon
xymon 246 Feb 27 13:54
xymon_vmstat.otpproxy1.5867
[root at otpproxy1 tmp]#
As i see
there are some files missing from tmp directory. I don't understand
why.
Can you please give me a
hint?
Regards,
Traian.

A simple ps -ef | grep xymon
will show what xymon processes are running and which user is running
them.
Look for 2 instances of
xymonlaunch.

Hi,

I don't know
where to check and what to
check.

Why are the FQDN named files owned by
root? this would seem to indicate that root is running
commands to output those files? xymon client should be
running as the xymon user only. Is something else on your
system starting up a second instance of the
client?

How did you install the client, manual
compilation or from one of the RPMs that others
have built?
If you did it manually then in
your init script add --hostname=XYZ as a parameter
to runclient.sh (this does appear to map to the
MACHINEDOTS variable inside
runclient.sh).

Hi,
I don't find any
CLIENTNAME variable, but i have MACHINEDOTS
variable in the runclient.sh which is said to be
"# This systems hostname".
I changed it to
use 'hostanme -s' and still the same result as
in the first message.
I have these files in
tmp folder:

Do you have any explanation why i have
all these files? Shouldn't it be only one named
msg.otpproxy1.txt and not the second named
msg.otpproxy1.temenosgroup.com.txt?

Traian.

To use the shortname just change the
CLIENTHOSTNAME variable to be the shortname, you
can use whatever you want aslong as it matches
with what you have in the main
bb-hosts/hosts.cfg.

On all of our systems I force the client to
use it's FQDN, in /etc/sysconfig/xymon I
configure the CLIENTHOSTNAME variable to be the
FQDN e.g. as part of our build script it
runs:
sed -i "s/#
CLIENTHOSTNAME=\"\"/CLIENTHOSTNAME=\"`hostname
-f`\"/g"
/etc/sysconfig/xymon

Hi,
I
have added the short name to hosts.cfg otpproxy1
not otpproxy1.temenosgroup.com. On
the Xymon page i have the conn, disk, cpu,
procs... all the tests are active there(it means
the server receives the client data
report).
But the client seems to send the
data report using the FQDN also and the server
sees it like ghost client.
How can i do to
prevent it.
Regards,
Traian.
Simple stuff first, do you have
the client listed in ~/server/etc/hosts.cfg
?
A little clarification: ghost clients
are generally clients that are sending data to
the server, but the server is not configured to
display them.
