[Xymon] Ghost client problems

Thu Feb 23 13:03:14 CET 2012

Hi,
This is my original question.
If i knew the answer i shouldn't ask for help.
I don't know where to check and what to check.
Regards,
Traian.

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?

Hi,
I have manually compiled it.
I start it using ./runclient.sh --hostname=otpproxy1 start command.(otpproxy1 is the client name in hosts.cfg)

Here you have the commands i gave:

[xymon at otpproxy1 tmp]$ rm -f *
[xymon at otpproxy1 tmp]$ ls -l
total 0
[xymon at otpproxy1 tmp]$
[xymon at otpproxy1 tmp]$
[xymon at otpproxy1 tmp]$
[xymon at otpproxy1 tmp]$ cd ..

[xymon at otpproxy1 client]$ ./runclient.sh --hostname=otpproxy1 start
Xymon client for linux started on otpproxy1
[xymon at otpproxy1 client]$ cd tmp
[xymon at otpproxy1 tmp]$ ls -l
total 44
-rw-rw-r-- 1 xymon xymon    41 Feb 23 13:13 logfetch.otpproxy1.cfg

-rw-r--r-- 1 root  root    246 Feb 23 13:16 xymon_vmstat.otpproxy1.temenosgroup.com.7223
[xymon at otpproxy1 tmp]$

After i start it i have only msg.otpproxy1.txt file in tmp folder but after a while i have also msg.otpproxy1.temenosgroup.com.txt file.

Why does it happen? What do i do wrong?
Regards,
Traian.

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.

Hi,
If i want to use the short name how do i proceed?
What config files from the client installation should I modify?

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.
