Email alert for port down

null_zeroroute · 10 February 2017 18:17

I’m trying to get an email alert for when a switchport goes down. LibreNMS sees the port go down, shows an alert on the notifications page, but no email is sent. Email transport works, I’ve tested it. I’ve gone through the docs and I’m apparently missing something. If email transport works, why does the event error suggest that “You must provide at least one recipient email address”? Any suggestions?

Here’s the event log for the device:

All of a sudden, an email is sent. I changed nothing in the email transport settings…

You need to share your settings with us. The error you’ve posted is because we can’t find an email address to send to so this all depends on what settings you have.

Also, an alert will only be sent after the delay and interval times have been reached, an alert in notifications doesn’t mean an alert has been sent.

null_zeroroute · 13 February 2017 21:38

Thanks, is there a quick way to put together the settings to share?

Also, as noted in my previous posts, mail transport tested ok and worked, and then all of a sudden email alerts started working.

Overall I’m struggling understanding alerting.

laf · 13 February 2017 22:14

Just screen shots is fine.

I’ve never seen mail not work then all of a sudden work, eventlog will tell you what’s going on there.

null_zeroroute · 14 February 2017 14:43

Understood, I thought it was strange as well. The only change I made was setting additional ports I don’t care about alerting for to “ignore”. No other changes, it just started working all of a sudden.

laf · 14 February 2017 23:25

Try running an alerts capture under edit device -> capture.

pastebin the output and link here.

I am having the same problem. I am able to get device alerts via email, but email alert on port down is not being triggered. Following is the Alert Debug.

Kevin_Krumm · 12 December 2017 13:23

Debug shows it being triggerd

jahanzeb · 12 December 2017 14:19

The debug is showing that port down rule is triggered but email is not being generated. For clarity my email transport is configured properly and am receiving alerts for device down but not port down.

Kevin_Krumm · 12 December 2017 14:56

Is that device has alerts disabled or in schedule maintenance mode?

jahanzeb · 13 December 2017 04:00

No the device is not disabled or in maintenance mode. And it is not one device, we have multiple routers and switches and we are not getting port down alerts for any of these.

Please validate your install and post the output.

Got the following output after running validate. Have fixed the log dir permissions, and have installed php70w-process for posix. Now getting OK. Will test again and let you know about alerts.

Same result, not getting email alert on port down.

Kevin_Krumm · 14 December 2017 13:38

And you are sure the email alert transport is working?

post ./poller.php -h HOSTNAME -d

along with the alert rule.

Your eventlog says no email address is provided. I can see from your settings you are using default contact only. If that’s a valid email then provide the format of what is, i.e [email protected] so we can try and test
