[Xymon] Proxy Priority?

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.
