URGENT - I have a problem with notifications

[gaguilard]

Any know bug for new XI version? - Nagios XI 5.8.7.

Notification stop to work. The server says that mail was delivered ( maillog) but there is not any email receives for clients.
Test email works.
I checked all again three times and all is ok.

Thanks for your answers.

Gastón.

Hello Gastón,

Thanks for taking the time to reach out on this issue, want to get the System Profile from you so we can see what is going on.

To send us your system profile.

• Login to the Nagios XI GUI using a web browser.
• Click the "Admin" > "System Profile" Menu
• Click the "Download Profile" button
• Save the profile.zip file and send via Private Message

Thanks,
Perry

Hi Perry:

I tried to download the system profile as you request, but I can´t download it, I received a message which says "refused to connect". I issued the procces descibed in https://support.nagios.com/kb/article.p ... ategory=44, and after this workarround was applied, the problem with the profile download continue.

I rebooted the server too.

Is there another way to get this info from nagios and send it to you?.

Thanks in advance for your help.

Gastón.

Hi:

One point to clarlify is, notification works well for users created as contacts ( created in admin users ), but not for contacts (CMM contacts)

I tested it creating a user for a contact and it user starts to receive emails.

I think that maybe ther is some problem with the script (php?) which convert emails to smpt emails.

I do not have more ideas... My books are burning.

Thanks!

Hello @gaguilard

Thanks for following up, let's run the 'getprofile.sh' via the script using a 'superuser' or root.

Code: Select all

rm -rf /usr/local/nagiosxi/var/components/profile.zip
/usr/local/nagiosxi/scripts/components/getprofile.sh SUPPORT

Then send the resulting /usr/local/nagiosxi/var/components/profile.zip​ file via Private Message.

Without reviewing the System Profile we can have you run the Core Config Manager (CCM) re-index.

[*]Reindex the Core Configuration Manager (CCM) configs[/*]

• Code: Select all

  rm -rf /usr/local/nagios/etc/import/*

• 1: Terminal command list all running /bin/nagios -> ps -aux | grep -E '/bin/nagios'
• 2: Terminal command -> killall -9 nagios (or pkill nagios)
• 3: Terminal command check to see if /bin/nagios processes are stopped
• 4: Nagios XI web console
  ==> Core Configuration Manager (CCM)
  ==> Config File Management
  ==> [Delete Files]
  ==> [Write Files]
  ==> [Verify Files]
• 6: Core Configuration Manager (CCM)
  ==> Under Quick Tools
  ==> "Apply Configuration"
• 7: Restart nagios.service by terminal command: systemctl restart nagios
[list]

• Code: Select all

  systemctl restart nagios

[/list]

Verify that the host and services look good in pre-flight with no errors in core by:

• Code: Select all

  /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

Please PM your updated system profile if the issue persists.

Thanks,
Perry

Hi Perry:

I made the proccess that you propose. All run with success.

I will check the notifications emails in the morning ( now here is 00:40 AM) and I will let you know about results.

Thank you very much for your help.

Kind regards.

Gastón.

Hello @gaguilard

Thanks for taking the time to send over the System Profile, and after review, we do see log message in eventman.log 'ERROR: User has (global) notifications disabled!' and to tackle the database issues that we see since it could be related.

[ERROR] mysqld: Table './nagios/nagios_logentries' is marked as crashed and last (automatic?) repair failed
211210 12:28:46 [Warning] Could not increase number of max_open_files to more than 1024 (request: 1075)

We see that the 'nagios_logentries' in the database has been crashing in the past and want to have you check on the size:

Code: Select all

echo "SELECT table_name AS 'Table', round(((data_length + index_length) / 1024 / 1024), 2) 'Size in MB' FROM information_schema.TABLES WHERE table_schema IN ('nagios', 'nagiosql', 'nagiosxi');" | mysql -h 127.0.0.1 -uroot -pnagiosxi --table

If you find that the tables sizes are large you will want to truncate:

Code: Select all

mysql -u ndoutils -pn@gweb nagios -e 'TRUNCATE TABLE nagios_logentries'
mysql -u ndoutils -pn@gweb nagios -e 'TRUNCATE TABLE nagios_notifications'

Want to also take a look at the "max_open_files" issue that is logged as well and here is a support document:

• https://support.nagios.com/kb/article/n ... s-513.html

If you see that your os is hitting as open file limits you may want to increase in '/etc/security/limits.conf'

Add/edit the following lines to the end of the file:
* soft nofile 10000
* hard nofile 10000
Save the file

Let's run through the database repair and let us know how it looks,
Perry
