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):

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 :

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

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.

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 ?
