Hello,
I'm using XYMON 4.3.12 to monitore ~1000 Windows and ~1000 UNIX. I have one xymon proxy dedicated to each type of OS. One Windows and an other UNIX.
XYMON server and proxy are running on Solaris 10 zones.
I currently have issue on the main XYMON server, during high activity time windows:
- The number of connections in the state CLOSE_WAIT (netstat ; port 1984) is increasing on the main server until it reach ~2014, then the xymon is nearly to crash (no
more web windows update, false alerts etc.). Only the windows proxy has also an increase of CLOSE_WAIT but 4 times less than on the server.
- In the main XYMON logs (whatever it is), I see this messages:
2015-06-07 03:20:11 Whoops ! Failed to send message (timeout)
2015-06-07 03:20:11 ->
2015-06-07 03:20:11 -> Recipient '<main XYMON server IP>', timeout 15
2015-06-07 03:20:11 -> 1st line: 'combo'
2015-06-07 03:20:16 Flushed 2 stale messages for 0.0.0.0:0
2015-06-07 03:20:18 Flushed 1 stale messages for 0.0.0.0:0
- The xymond test shows that the Incoming Messages rate is limited to 150msg/s.
- High activity is correlated with BBWin.cfg update. I'm using BBWin in local mode with the bbwinupdate feature. The BBWin config files are stored on the XYMON server
and downloaded/checked by the BBWin agent.
Parameters that seems to have effects:
xymonserver.cfg
MAXMSGSPERCOMBO (on the proxy, should be low)
tasks.cfg
timeout of xymond and xymonproxy set to the possible lower: 5mn
xymongen => INTERVAL changed from 1m to 2m
These actions seem still not to have enough effect. Please advise.
Cordialement, Regards,Mit freundlichen Grüßen,
Gautier BEGIN
