I have 7363 hosts being monitored in my environment. Tue Oct 4 10:05:58 2011
Statistics:
Hosts : 7363
OS: SuSE Linux Enterprise v11.0
I found network I/O a challenge, and had to set up a bbproxy server and split the ping test over two Xymon servers, each server handling about ½ the load. Time spent on ping tests (on each server) is about 170 seconds.
Proxy statistics Incoming messages : 3332629 (48 msgs/second) Outbound messages : 1778658
The disk i/o with this many hosts is also difficult - at least on my hardware (IBM x225 server). I also disabled [hostdata] in hobbitlaunch.cfg - my systems could not keep up with the i/o.
I cut down on message traffic by using a the 'ignore' and 'trigger' capability of the logfile checker in client-local.cfg, thereby filtering at the client; eg: log:/var/log/daemon.log:4096 ignore (upsd.*: Set variable|apcsmart.*enum |dhcpd: |xinetd.*: |squid.*: |ntpd.*: |Connection from |logged out) trigger shutdown

I'm planning to use XYMON with a big amount of clients: 1000 and then 4000.
Is it possible ? Are there some tipps and limitations to know ?
