Hello
In our company, we got ~10 000 devices split into 10 countries :
19 hobbit clusters in total. (1 hobbit cluster in each Datacenter).
we use bbproxy to report to one single hobbit cluster (central):
WED OCT 5 07:37:25 2011
Statistics: Hosts total : 10866
Incoming messages/sec : 478 (average last 300 seconds)
The maximum of hosts for a local hobbit cluster is 3655 :
Here the stat of this local cluster :
Statistics: Hosts total : 3655 Hosts with no tests : 60
Total test count : 9809 Status messages : 10151 Alert status msgs : 0
Transmissions : 326
TCP test statistics:
TCP tests total : 6214
HTTP tests : 2342
Simple TCP tests : 3872
Connection attempts :
6214
bytes written : 396441
bytes read : 24395876
TCP tests completed 134011.876173 30.657820 PING test completed (3650 hosts) 134012.458682 0.582508
TIME TOTAL 44.107030
Incoming messages/sec : 173 (average last 300 seconds)
The hardware is a cluster of 2 HP DL360 G7 with 4 SSD drives in raid5 for /opt/xymon/data.
We chose SSD for I/O performances.
load average: 0.74, 0.84, 0.82
We use heartbeat for VIP and DRBD for replication.
We didnt disabled hostdata but maybe we should do (we have a couple of scripts to clean up the hostdata, histfiles, etc).
On the local cluster /dev/drbd0 34078720 11545129 22533591 34% /opt/xymon/data /dev/drbd0 122G 69G 47G 60% /opt/xymon/data
-> 11 millions of files
On the central cluster /dev/drbd0 89522176 77497570 12024606 87% /opt/hobbit/data /dev/drbd0 673G 458G 181G 72% /opt/hobbit/data
-> 77 millions of files
it becomes high.
sometimes we experienced ASR on hobbit servers :/
Cheers Nico

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 ?
