Hi to all!
I've just installet xymon server (on Centos 7), but I've 2 problems:
All my linux machines (xymon server included) ha the clientlog column (with all the client's info), but no cpu, disk or memory column.
The info column af any objecy (linux machines, windows machines, other objects) if selected, gives a "No such host" blank page.
Any ideas?
Thanks! Luca

Check that the hosts.cfg entry for the machine doesn't have "NOCOLUMNS:disk,cpu,memory".
Check the Xymon logs, particularly "xymond.log" and "clientdata.log".
Check the "Ghost Clients" report.
Or, might it be something as simple as a full filesystem, or wrong permissions perhaps?
Can you provide the output of this command, to show the [df] section of the client log:
$ xymon 127.1 'clientlog server-name.example.com section=df'
The "[df]" section of the client log is used to generate the cpu status, and with no status, there's no column.
The client message data goes into xymond from the Xymon agent running on the client machine, by connecting to the server's xymond process on TCP/1984. The xymond process then pushes the client data onto the "client" channel. The xymond_client process subscribes to the channel and so it receives the client data. If the machine is a Linux machine, xymond_client then parses the [df] and [top] and [free] sections (for other OS types, different sections are parsed), and xymond_client creates status messages for "disk", "cpu" and "memory". It injects these status messages into the xymond process via TCP/1984, to appear on the Xymon web page. See here for a reference chart: http://tools.rebel-it.com.au/Xymon%20-%20the%20Big%20Picture.pdf
Perhaps run the xymond_client process with the "--debug" option, and see if it indicates that it is getting the data. Also, check the "analysis.cfg" file, which is used to specify the behaviour of xymond_client, and might cause it to misbehave.

Problem resolved just now: it was a virtual network card (on the xymon server) that somehow interfered...!
