Nagios Support Forum

Hi all,
Created a new contacts named Sistemisti_linux. (generic-contact)
I add a new host , hostgroup and one service but not receive alerts when power off the monitored host.
Nagios shows that the notifications are sent, but the contact is not receiving them
Although the Test Send Email Is received. ( i try with my account not contact Sistemisti_linux but i think is the same)
Notifications is appeared in the console.

I am using Contacts only:
notify-host-by-email and notify-service-by-email


Thanks
Diego

attached screenshots of the nagios conf

Are you able to receive both the test emails and the notification emails at the email address for nagiosadmin?

If you PM me a system profile I can diagnose further. Get one by going to Admin (top menu) => System Profile (in the left menu), then clicking the blue button.

Hi

Did you setup the backend postfix to relay for you? (you need to if you haven't)

https://www.linode.com/docs/guides/post ... lay-server

You could also do this to make it use Admin > Email Settings SMTP settings:

https://assets.nagios.com/downloads/nag ... Mailer.pdf

The Test Email button is not a valid test for this. You'll need to do it this way:

Please go to Admin > Manage Email Settings:
- Make sure Logging is checked
- Click the Update Settings button

Then run this tail command as root (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 (please test via the instructions below exactly).

How to submit passive results for testing:

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

Go to Home > Host Status:
- Find the Host 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.

Thanks for your help

i have configured postfix and done some command line tests. all right.
there's one more thing I don't understand.
The log below shows a notification and sending the email everything works but .....

if I do a test with one of my hosts that I entered with the wrong ip to make it alarm it does not work.
i tried to force the check from nagios but nothing does not track anything.

other questions:
how do i modify [email protected] in
[email protected]? and the text of the email sent?
what are the parameters defined on the nagiosxi web page in setting mail for?


in my old nagiosxi I used my own command created that used sendmail another system but now I would like to use the one chosen by you

Thanks

was sendemail

I try new test and log write:

[root@nagiosxi01 ~]# tail -Fn0 /var/log/maillog /usr/local/nagiosxi/tmp/phpmailer.log /usr/local/nagiosxi/var/eventman.log
==> /var/log/maillog <==
tail: cannot open ‘/usr/local/nagiosxi/tmp/phpmailer.log’ for reading: No such file or directory

==> /usr/local/nagiosxi/var/eventman.log <==



other thing that I have noticed: hosts that have admin as group work and send mail.
while those who have only the contact I created do not send mail

Admins use generic-contact that I have configured with my email.
but I cannot use a single contact, I have to work at a higher level to have many different groups linked to the services we provide.

bye
