[Xymon] convert to FQDN

[Root, Paul T]

You will want to use   xymon $SRV "rename <short> <fqdn>" to rename each machine.

You will also need to restart the client on each machine changing its reporting hostname from short to FQDN.

I did it the other way a number of years ago.

Subject: [Xymon] convert to FQDN

Greetings -

I've been using Xymon (and Hobbit, and Big Brother before that) for many years. And unfortunately a decision I made LONG AGO is now rearing its ugly head: Fully Qualified Domain Names. 

Long ago I decided to use short names, and for the most part this has worked well. But now I need to convert to FQDN, and want to make certain I know all the steps involved:

- edit hosts.cfg, perhaps use the CLIENT tag until I have all clients use FQDN

- edit analysis.cfg, also changing hostnames

- ditto for alerts.cfg

- edit xymonserver.cfg, change FQDN to TRUE

All the above is relatively straightforward. But something is reminding me about all the RRD files I have for my hosts. Do I need to rename them as well? Or will a "xymon 0 'rename SHORTNAME HOSTNAME.corp.org' " take care of this?

And is there a way to have Xymon running to receive all the RENAME messages, yet disable network tests so new "phantom" hosts are not created?

Thanks for reading and passing along any suggestions you may have.
