Re: Debugging email notifications in version 19.1.0-1

Sigh, and you are correct.

Apologies to all as decided to try email on a different, more cleanly installed (apparently) instance of 19.1.0-1 and the DEBUG worked fine on that instance. It said to set an email address for the admin account (I’d only set up my own account with email.) When I added my email to the admin account I began receiving emails. Many many emails.  Oddly emails where the “Event Notifications” page had no definition of the notifications I was receiving on many net-snmp services I’ve written, but never defined notifications for them yet so unclear why they are working.

Anyway this is great news and very red-faced at wasting your and Michael’s time. I believe I’ve an idea how the install of 19.1.0-1 got munged so will save the config and re-install from scratch next week. I may have more questions on email control as mentioned but I’ve a feeling with some DEBUGing enabled I may be able to find some on my own.

Big thanks again and have a good weekend,
Paul

Any chance you may have disabled Notifd at some point in the past, via service-configuration.xml ?  'service opennms -v status' shows it running?

Shot in the dark, because I'm out of ideas.  I ran several releases of 19.x and had notifications working on all of them.  Never had a problem there, unfortunately.

I understood that value of “true” for 'org.opennms.core.utils.debug’ to be the default as it was commented out in javamail-configuration.properties
but I tried uncommenting to actually explicitly set it prior to posting.

I had a mail admin confirm that nothing is being sent to the mta at port 25 when I enter the wrong password into the gui.
And as you see from my telnet, if something had been sent, it would make it to my inbox.

Yeah, that's odd.

Try adding 'org.opennms.core.utils.debug=true' in javamail-configuration.properties and see if you can get better info out of notifd.log?  if you stop your local mta and listen on port 25 with netcat or similar do you see any attempt by OpenNMS to connect to port 127.0.0.1:25<http://127.0.0.1:25>?

Hi Dino,

Using the “Search” feature under Status->Events, I used the “Exact Event UEI:”
field and entered:     uei.opennms.org/internal/authentication/failure<http://uei.opennms.org/internal/authentication/failure>

and get 10 events that do look like my attempts at using the wrong PW. Here is an example:


As for the javamail and mail transport agent, Michael and I went through those earlier in the thread, but happy to try anything further you can suggest. Sadly the DEBUG level of logging in notifd doesn’t create anything in the notifd.log file. If we could figure out why that doesn’t behave, I am fairly certain it would point us straight to the actual issue?

Thanks you for your time as well,
Pail

Hi,

I would start by verifying the event is actually fired (Can you find it in Status -> Events?), and that it matches the filter for the notification ( '(IPADDR IPLIKE *.*.*.*)' by default).  Does the notification show up in Status -> Notifications?  If those check out, i would suspect your javamail config and/or your local mail transport agent.

Michael,

The addition is correctly reflected in the gui, but no email sent when I generate the event with the wrong PW.
What steps are available to debug this further?

Thanks again,
Paul

Maybe we should focus on the Failed Authentication not working, since that one is a not one I created?

Hi Paul,

about enabling debugging for notifications: I really can’t remember I was ever using this. I set up notifications about 10 years ago and since then always copied the working config ;-)

I didn’t find any obvious error in your config, but the filter rule might be the problem.

If you don’t see notifications in the list it probably won’t be the email part that is failing – I assume your rule doesn’t match. I would


-       Start without this rule

-       If notifications are generated look out it the mails are coming

-       Maybe the filter roule would be better using something like

      <rule>(catincstaleNFS)</rule>
assuming that staleNFS is a category


Michael
