Nagios Support Forum

hi,

I am trying to set up the email functionality on Nagios XI VM's but it is not working.

I have tried both the options

- postfix
- SMTP (office365)

Please support here if some configuration is required initially.

Thanks..
Amit

Did you follow this guide here?

https://assets.nagios.com/downloads/nag ... ios-XI.pdf

Please go to Admin > Manage Email Settings:
- Make sure Debug Log is checked
- Click the Update Settings button
- Take a screenshot of the settings here and send it to me

Then run this tail command (and leave it running):
Then force a notification to be sent then send me the full output of the tail command above and any errors you see on the screen.

Does it work if you go to Admin > Manage Email Settings > Send a Test Email?

Please include all output from the screen and any errors that you receive.

NOTE: I'm just including this info in case you're unsure how to test

How to submit passive results for testing:

For Hosts
------------

Go to Home > Service Status:
- Find the Service and click on it
- Click the + tab
- Click the "Submit passive check result" link
- Select the Check Result and type in some text for the Check Output
- Click the Submit button

NOTE: By default, passive_host_checks_are_soft=0 is set in your /usr/local/nagios/etc/nagios.cfg, this differs from services in that when you submit a passive host check result it immeditely goes into a HARD state (and should send a notification if configured to) instead of going into a SOFT state like services do. (notifications are only sent on HARD states).

For Services
----------------

Go to Home > Service Status:
- Find the Service and click on it
- Click the + tab
- Note these two rows:

State Type: Hard
Current Check: 1 of 4

Those columns tell the current State Type and the Current Check number. In order to generate a notification for a service you will need to submit MULTIPLE problem check results (the number that you need to submit is determined by the last number in the Current Check column, that is the max_check_attempts setting). For services, when you submit a passive check result, each result that you submit will be a SOFT state until you submit enough to hit the Max Check Attempts setting that you've defined on the service, only then will the service enter a HARD problem state which will generate the notification (just remember, notifications are only sent on HARD states).

- Click the "Submit passive check result" link
- Select the Check Result and type in some text for the Check Output
- Click the Submit button
- Submit as many as you need, right after another, until the service enters the HARD state so that a notification will be sent

NOTE: When coming from a HARD problem state (whether we are talking about hosts or services) if you submit an OK passive result it should fire off a recovery notification after a single passive result has been submitted.

Hi ,

I did try to observe the logs and pfb the output.

Does it work if you go to Admin > Manage Email Settings > Send a Test Email? - NO IT DOES NOT WORK..This output is for the same..

Once I am clicking the send test mail button, Nagios UI is getting stuck and I have to restart the httpd service on the server.

The above error looks like Nagios XI cannot make the connection to smtp.office365.com with the information provided.

Hi,

Can you provide me some commands to check the smtp connection from the nagios xi server itself.
however I am successfully able to telnet on smtp.office365.com 587.

Thanks..

Are you sure you have the correct username/password?

yes i am using correct username and password but still no luck.
whenever I am trying to send some trial mail the whole GUI is getting stuck and I have to restart the httpd service on nagiosxi server.

Hmm, are you sure there isn't something between the XI server blocking the connections to smtp.office365.com ?

Can you ping it from the CLI? or telnet to port 587

Hi,

[nagios-prod@oc-monitoring-prod ~]$ telnet smtp.office365.com 587
Trying 40.101.124.194...

Hello ThriVikram,

This is likely an authentication issue. Please check the SMTP login and password to make sure there are no special characters in the password, and check if the SMTP server is set with the correct security and port numbers.
You can take a look at the phpmailer.log file to see what the output says.

Head to the "Manage Email Settings" and click on Debug Log then update your settings.

Under , edit line 329 to show
Send a test email and see the output on the top of the web UI. It should be a lengthy output but towards the end, it will give you an SMTP error such as
