We need to look more closely at the zenactiond logs.  The "zenactiond debug" command is a toggle - the first one turns logging to debug, a second "zenactiond debug" sets logging back to normal.  This is on the running zenactiond daemon.  The other alternative is to to set debug-level logging in the zenactiond.conf file in $ZENHOME/etc :

logseverity 10

With this, you then need to restart zenactiond.

You should see LOTS of chat with logseverity at 10.  Each notification you have should be tested to see whether it is valid for this event.  Here is a snippet from my zenactiond.log when Zenoss could not access our mailserver:

You can see it deciding that zen42_email_traps_su is a valid notification (after discarding a couple of other notifications), finding the targets ( ['jane.curry@skills-1st.co.uk'] ), constructing the email subject and body, and then the error ( [Errno -2] Name or service not known.. ), when it couldn't find our mailserver.

The little bit of log you showed didn't look like you were really in debug mode.  When you are drowned in logging stuff, try searching for ERROR for a start.

Cheers,
Jane
