Hi Martin,
Thanks so much for confirming this. I'll try the ignore statements. It would be wonderful to get the maxdata working - I was thinking of asking Etienne about it - the company is so dependent on xymon now.
Also there is David Baldwin's perl script (and snare), so some options now.
cheers, P

You are absolutely right, the maxdata does not work, but everything else do.
I got at first 10MB from my DC, but after putting a lot of ignore clauses, I got It down to 1MB.
So that part works. (hadent come so far previous)
I have an consultant who is good on C++, I will let him have a look at it, with low priority, in August.
Cheers, Martin

Hi Martin,
Yes, I've seen that post and used those settings and they don't work - eg I tried setting the maxdata to say 1024 bytes and the client definitely sends more than that. It is sending 80-odd MB when I've limited it to under 20K (we are generating a lot of logs at the moment).
If it isn't too much trouble, could you pls try setting maxdata to a small number and see whether it is truncated on the respective msgs page? You'll have to check the local copy of clientlocal.cfg (under \tmp) to make sure it has updated. I've had to shut down the client, delete that file and then restart it to force it.
cheers, Phil

Hi
Have a look at the last post in this thread
http://sourceforge.net/p/bbwin/discussion/460874/thread/04a00deb/?limit=50
I have tested it, IT WORKS , and it explains HOW !
Martin ( who have been struggling with this a lot, whithout success)
Phil,
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?
I have it working, but I don't actually use BBWin for event log reporting - I forward all my event logs using Snare to a central syslog server and have my own checking against that server-side - see http://xymonton.org/monitors:winevtmsgs.pl
My client-local.cfg for Windows clients includes the following to filter out everything client-side. You may be able to play with the ignore rules to tune it a bit more to your needs while still reducing the size of the report. By checking the BBWin\tmp\msg.<clientname>.txt file you should see what is taking up all the space.
log:eventlog_security:10240
ignore .*
ignore .
eventlog:security:10240
ignore handle
ignore .*
ignore .
eventlog:System:10240
ignore .*
ignore .
eventlog:application:10240
ignore .*
ignore .
eventlog:directory service:10240

David.
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:10240
I 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:1024
It 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
