A large number of event handlers are logging to the eventd.log file rather than the log file belonging to the event handler.
to see this download the attached tgz and untar' it
grep – '-Thread' eventd.log | grep -v EventIpcManagerDefaultImpl
You can see a lot of messages that are doing the particulars of a deamon's event handling but are not in that daemon's log file
There seems to be a little randomness about this I've also heard that sometimes the eventd messages are in collectd's logs
Just trying to figure out how this worked before and what broke it.
Note I have already hacked the onEvent method for collectd to force setting the prefix.
