Sean,

The client report is generated only once and sent to all reporting
servers. If you want to do the files test on only 1 of those, so be it,
but the data needs to be there in the first place. The servers not doing
the files test will just ignore that section of the client data.

The cached copy of client-local.cfg which is used to configure the log
files to include is delivered from one of the servers reported to (it
actually gets returned to the client after the TCP socket is shutdown
when the client report has been sent to a server). If this process gives
different results for different servers, then no guarantees on anything.
Best to keep them all in sync, then you'll get the same thing each time.

David.
Yeah, I know if the files are all the same, I wouldn't have issues

However, some of those displays, want no test of "files"

The other displays, I do want tests of files… that's why they were
different

I didn't notice it was working like this right away – a majority go to
1985 local… but not all

Sean,

You can sync client-local.cfg if you designate one of the servers as
master. If all the servers are the same, it won't matter which one
responds.

xymon master "config client-local.cfg"

Will retrieve the master client-local.cfg.

David.

I have a setup like this:


+------------------------+        +----------------------+
|  xymon:1985            |        |                      |
|------------------------|        |  Downstream client   |
|  xymonproxy:1984       | <-----+|                      |
+------------------------+        +----------------------+
    • |
    |
    |
    +----->   proxy sends to localhost:1985, and upstream host1 1984,
upstream host2 1984

[this is repeated across several sites]


The issue is, when downstream client looks to get it's config – in
some sites, it gets the local-client from xymon:1985 host, but in
others, it gets it from upstream hostX:1984


The xymondproxy in the tasks.cfg is identical in each place (--server
localhost:1985, host1:1984, host2:1984)   -- so I am confused as to
why some get localhost, and some do not — the local-client is
different in each place – and I'D prefer some setting I am missing
(?) so that it always gets the local-client from the xymon:1985 instance.
