cannot seem to add a lot of hosts

Hi


I have got a new install of Xymon 4.3.30 onto Rocky 9


I have got a pre existing install of Xymon 4.3.30 on Centos 7


I naively thought once I had configured everything, that I could copy the whole hosts file from my pre existing install onto the new one, and job would be a good un. BTW this is the method I had used for loads of OS upgrades in the past and it always worked


If I do that, all I get is the status for the server, and all the new hosts subpages etc just show as text but no test data for conn, cpu etc.


I made the file waaaay smaller, and it still did the same


I started from scratch and added 2 hosts and they started populating test data.


I augmented that hosts file with just 20 hosts and it then doesn’t do anything again.


Any ideas where I should look for issue?


Thanks


David

Check the log files in /var/log/xymon (or wherever you configured it).  Also, if you have SELinux=enforcing (rather than permissive), it can block a lot of the Xymon processes from running.  That is set in the /etc/selinux/config file.
FYI, I am also running on Rocky Linux 9.

Hi David,

Does the new server have the same IP address that the old one had?

Do you have firewalld running?  If so will it allow connection on port 1984?

Anything useful in the logs?

Regards
Jeremy

Hi Chaps


Thanks for response so far. Maybe I have given a rubbish explanation.


It’s a different IP address


I have SElinux switched off (I have had issues with that in the past)


My Xymon install is actually working, the issue is I seem only able to add 2 or 3 hosts at a time, which means it will take a considerable time to complete my migration.


If I add a load, it displays the name but not the wee dashes where the conn, info, trends would go initially and then be filled out on next cycle.


Thanks


David

Hi,

Remark, if you copy over the tmp/xymond.chk file from the old server, you will get all the existing hosts and services.
If a host is not sending any data for a test, that test will go purple.

That will make it easier to make sure all hosts are sending all data to the new xymon server.

I've experienced strange issues like that before, especially if the xymon server is running on a cloud hosted platform. Unless you've got a config syntax error somewhere that isn't obvious, a server reboot usually solves it for me.
