Setting up a Xymon proxy server
Hi all,
I am unable to find any documentation on the configuration of the hosts files when using xymonproxy, can you help?
I have a number of clients client that have the Xymon proxy server configured as their Xymon server in the xymonclient.cfg file: XYMSRV="10.5.1.205"
So they will send their status messages to the proxy server.
The proxy server only has the [xymond], [xymondproxy], [xymonclient] and [combostatus] sections configured (do I need xymonnet and xymonnetagain?), this seems sensible to me.
The proxy server also has the clients configured in its hosts.cfg file since it needs to know who to poll for.
The question is, how do I then configure these clients in the main Xymon server? Do I have them in the hosts.cfg file there as well? If so how do I stop the main Xymon server from pinging them? Also, given that these clients are in a group, how do I get them displayed as a group in the Xymon web pages?
I have gone through the xymonproxy and hosts.cfg man pages but to no avail, so am turning to you all.

Yes, they need to be in the hosts.cfg file on the main server, otherwise, they would be ghosts.
Put the noconn directive in the servers hosts.cfg file after the # for the proxied machines.

This approach will work, but the NET tag was specifically provided for this case, and would mean you aren't forced to have diverging hosts.cfg files across your Xymon servers.
Devmon also respects the NET tag.

Brilliant, my thanks Buchan and Paul for your assistance.
I found that if I wanted to use a single hosts.cfg file as Buchan suggested then I had to create a NET tag for every entry and adjust it for those in the new network. This was easily done by adding "NET:default" on to the .default. entry and setting XYMONNETWORK="default" in the xymonserver.cfg file.

Well, strictly 'proxy' means to only proxy reports from clients on to the display server, but in many cases the proxy is there to reduce the firewall access required, and typically this means that the proxy must do the network tests as well. If so, then yes, xymonnet and xymonnetagain should be enabled.
The proxy server also has the clients configured in its hosts.cfg file since it needs to know who to poll for.
The question is, how do I then configure these clients in the main Xymon server? Do I have them in the hosts.cfg file there as well?
Yes.
If so how do I stop the main Xymon server from pinging them?
In any environment with multiple instances of xymonnet, you should set the XYMONNETWORK variable in xymonserver.cfg on each server running xymonnet, and in hosts.cfg use the NET: tag with the value of the XYMONNETWORK variable of the server whose xymonnet task should do network tests for it.
This allows you to use the same hosts.cfg across all your servers (otherwise you are most likely to have diverging hosts.cfg files across your Xymon servers, requiring manual merging and updating of multiple files etc.).
Also, given that these clients are in a group, how do I get them displayed as a group in the Xymon web pages?
Using the normal page, group, group-compress etc. statements?
(But, IMHO, it is wrong to mix the definition of what to test with how to present the display, it would be better to split them IMHO).
