[Xymon] Big Environment

Tue Oct 4 16:12:57 CEST 2011

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

Hello,

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 ?
