Thanks, David.... Yes, I don't have clientversion.cfg either - I tried putting in "0.13" in a file of that name in \etc, the client says it reads it and no more error, but who knows what this does or doesn't do...
Anyway, on to the rest. As I described in the previous email, I did let the clientlocal.cfg update successfully. But as soon as I add the msgs.dll agent bbwin still ignores the maxdata parameter, tries to send everything and xymond drops the connection before completion (this latest time at 31MB).
Do you have this working? Does it actually reduce the size of the msgs sent?
thanks, Phil

Phil, Thanks for the reply.
Before continuing, what is supposed to be in logfetch.status? and in clientversion.cfg?
logfetch.status will possibly only exist if you are checking any regular logfiles - e.g. if client-local.cfg contains something like:
[win32] log:c:\WINDOWS\WindowsUpdate.log:20480
clientlocal.cfg will contain the relevant section similar to your 4 line example below. clientversion.cfg doesn't exist on my systems
As BBWin runs, check the size of clientlocal.cfg - if it gets wiped, try saving the contents back again. Also, updating BBWin.cfg should cause BBWin to run immediately without restarting the service. I haven't played around with commenting out msgs.dll
David.
So, I have one server with the msgs.dll out of the config. It has been running for many days with the client updating fine. I redid the xymon client-local.cfg, stopped bbwin, deleted \tmp\clientlocal.cfg and restarted it (as it wouldn't update), the \tmp\clientlocal.cfg now reads what the client-local has:
eventlog:application:1024
ignore BigBrotherXymonClient
eventlog:system:1025
eventlog:security:10240I let that run a cycle, it still updates OK. I then put in the msgs.dll statement in BBWin.cfg; that registers and BBWin.log shows:

If the eventlog data being transmitted is too large to transmit until the clientlocal.cfg is sent back and populated in BBWin, then why not disable the eventlog client in BBWin until it successfully sends 2-3 status messages? By that time the clientlocal.cfg will be populated on the client and you can enable the eventlog reader again and everything should work fine.

Phil,
Just found a fix that works for me :) I've been having difficulties setting up the bbwin client (ver 0.13 going to xymon 4.3.10 server) running on win7 sp1, 2008r2 and win2012 boxes in central mode. I've had zero response from the bbwin-help forum for this, so please bear with me.
For background: I can't get the bbwin client to stop sending all the logs, it ignores any maxdata parameters I use. Eg:
eventlog:system:1024It sends everything anyway. If I use log:system:1024, the bbwin client throws an error that it can't find the system log file. It does find the file without the maxdata parameter.
One problem with the settings in client-local.cfg on the xymon server is that they only propagate to the client after a successful sending of a client message. The mechanics is that after the client message has been sent, BBWin does a shutdown on the write socket and then reads from the read socket until EOF. If the write socket is never shutdown because the server breaks the connection due to flooding, then the client-local.cfg section will never be sent to the client.
I've previously attempted to manually create C:\Program Files(x86)\BBWin\tmp\clientlocal.cfg to trick it, but with limited success. Just played around with it again - with client reporting to my primary server I just got it going - previously I was reporting to 2 servers. The trick seems to be in having logfetch.status also created. I then modified my BBWin.cfg back to 2 servers and it broke again. Maybe the 2nd server is responding differently. It is undefined which server's clientlocal.cfg to believe anyway :) Swapped the order of the servers around and it seems stable.
If the server just discarded all the flooding data beyond MAXMSG_* and then returned the client config section anyway maybe it could be made to work, but there may be good reasons why that would not be sensible. This aside, I do need to get this working as I have to start monitoring 10 new windows servers and have to monitor the event logs, so I can't just stop sending them as has been suggested. Yes I could do some powershell scripts and send them via bbwincmd but the bbwin client is made for this task.....
So, looking at this from the other side, the xymon server appears to be resetting the session after about 22MB of data has been sent (I know, this is ludicrous, but it is windows). Nothing in the xymond logs (except for the occasional data flooding error ("1st line client", always)); on the client side it reports it can't send the data to the xymon server.
Depending on what auditting you have enabled, 22MB is very easy to achieve! Turn on Security event logging including success and failure and it's almost guaranteed :)
David.
I've set the MAXMSG_* to quite silly levels:
ipcs
------ Shared Memory Segments -------- key shmid owner perms bytes nattch status 0x01034be7 16908288 xymon 600 102400000 2 0x02034be7 16941057 xymon 600 102400000 2 0x03034be7 16973826 xymon 600 102400000 2 0x04034be7 17006595 xymon 600 102400000 2 0x05034be7 17039364 xymon 600 262144 1 0x06034be7 17072133 xymon 600 32768 1 0x07034be7 17104902 xymon 600 102400000 2 0x08034be7 17137671 xymon 600 102400000 2 0x09034be7 17170440 xymon 600 131072 1
Anything up to and including this size has no effect on the problem.
Looking at the tcpdump stream, the bbwin client sends data normally with regular ACKs from xymond till around that 22MB mark then xymond responds with a FIN packet, then with RST packets and the session shuts down. Nothing in the packets themselves indicate what the problem is.
If anyone can help with this, please, it would be great.
thanks, Phil
