It gives error in librenms.log:

Hmm, it doesn’t show where the bug is triggered from. Is there a backtrace with the error in the log?

When i hit “Test Transport” it shows message in /var/log/httpd/access_log:

10.126.XXXX.XXXX - - [11/Sep/2023:15:23:23 -0400] “POST /alert/transports/1/test HTTP/1.1” 500 69 “http://toc-librexxxx.xxxx.xxxx.edu/alert-transports” “Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/116.0.0.0 Safari/537.36”

and above message in librenms.log

I got quiet the same problem, the mail is sent using the test button (from alert → alert transport → orange button) but it is not working/triggering when i associated it in a “Alert Rules” → “transports”

[jamos]

A followup on mine. A Warning level alert did trigger this morning for an environmental device but no Criticals have gone off even when I purposefully powered down a switch. My test transport button also fails with a general error.

LibreNMS | 23.8.2-42-g49d66fa31 (2023-09-14T00:10:37-04:00) - the same issue.

I created Dummy and Syslog transport. Both have the same issue.

Fix bug in sysContacts email collection

[macaddr]

i finally make it works, adding the default transport template from docs in a new alert template.
I thought the default template will be apply as default template but not, i have to add it manually.

[dlesel]

LibreNMS | 23.9.0 (2023-09-15T09:05:55-04:00) - works! But click on the test button still shows the “Test mail failed - general error”.

[dlesel]

Thank you Tony!

[jamos]

Alerts seem to be functioning properly! As dlesel said I still get an error on the test button but it goes through without issue. Thanks everybody!

I have same issue. Happened the same time as OP.
As i understand, people in this thread only checked the situation, when there is custom email transport created and assigned to alert rule?

What about global default mail transport? Should it work after fix?

I have configured only default one, and set it to issue alerts only to admins (general alert settings). Alerts do not come through.

I tested with custom mail transport and indeed it works.

Should i debug my case further? If so what should i check?
There is no errors in librenms.log
Running test-alert.php not giving any apparent errors. There is line added to event log “Issued recovery for rule … to transport ‘mail’” (same for none recovery).
