Good morning all,

We had started to use our XI server again and getting ghost emails from previous down alerts that either A) The client is no longer in the configuration or B) The host is reporting down and its currently up. We suspect these are emails that should have been generated and should have been sent out but didnt due to other issues with XI. Is there a way to clear this, if there is a cache producing these emails as we have already received 200 emails prior to shutting down the email server again.

Hi,
Please try the below command (NOTE: this is a ONE line command):

Good afternoon,

We are getting the following error:

No database selected.

Hi,
Please try this (added -u root).
NOTE: this is a ONE line, so make sure you copy all:

echo "truncate table xi_events; truncate table xi_meta; truncate table xi_eventqueue;" | mysql -uroot -pnagiosxi nagiosxi

Just to update posting,

We were able to run command but waiting on team to turn on smtp server to confirm that this resolved the massive amount of previous non sent alert emails from being sent.

OK ... just let us know!!

Good evening,

We have enabled the smtp server and verified that the server is operational from the smtp server itself but it seems that nagios is not communicating properly with the server to send the emails. I have tried so far the following troubleshooting steps and will continue to look further into the logs and enable debugging.

- Tried switching email addresses for the account
- updated existing email address and saved to account again
- used a different user account
- Used multiple machines for testing
- Changed the contact for a machine as a test to have the direct contact of the account I was using

What do you mean by "not communicating properly with the server"? Where do you see that? Please include any error messages you see.

What happens if you send a test email from Admin => Email Settings? Any error messages there? Does the message arrive in your inbox?

Is Nagios XI set up to use an SMTP server, or sendmail?

Good morning,

When enabling debugging using the following guide:
https://support.nagios.com/kb/article/p ... g-820.html

We received the error that it could not connect, to find out that our connection information was provided incorrectly.

We have not seen the flood of emails come in after turning it back on after using the truncate statement listed above.
