Happened to me too, on some servers we inherited. Event logs were just too
dang big ! we'd need to filter at the source to not send so much, or better
yet get them to not log so much (we moved on,so I didn't end up
implementing this)

Thanks you for the insight. We will try this and report on the results.

Scott,

I have the following in my /etc/xymon/client-local.cfg file to try to kill
the event logs completely - note that the client has to report successfuly
to pull this from the server. If that fails, you can paste directly into
C:\Program Files (x86)\BBWin\tmp\clientlocal.cfg

[win32]
log:eventlog_security:10240
ignore .*

I process all my Windows servers event logs on a central syslog server
forwarded by SNARE using a custom test.

David.

 We are at xymon version 4.3.3 and bbwin is at 0.13.

We’re trying to completely shut down all Windows event logs being sent
from the clients to the Xymon server. We experimented and only seemed able
to achieve this by deleting the:


                <load name="msgs" value="msgs.dll"/>


line and the entire “<msgs> …</msgs>” stanza from the local BBWin.cfg. We
thought we had a recipe for success on the rest of our Windows clients but
when we started trying to make it work on two other boxes, we found that
the “procs” and “timediff” tests went purple!


We experimented by putting parts of the <msgs> … stanza back in but we
found that (apparently) the client data was not making it back to the
server from the client after the mods. So – we got it working on our test
box, but on two other “live” boxes it failed and interfered with other
tests.


This is a hot item for us since our Hobbit server is being overwhelmed by
incoming data, in large part coming from these huge Windows event logs.


Thanks!
