Send a notification only once

Using Nagios XI. I have a service that I want to send one alert only. I have tried setting the notification interval to 0 (as suggested by a 2012 post) but it still sends an alert every 10 minutes. Any suggestions on how to make this happen? Thanks for any help -- Tom

Do you have any escalations? Did you apply the configuration after setting it to 0? Please attach your objects.cache file which you can find with the command find / -name objects.cache. The likely location is /usr/local/nagios/var/objects.cache. You won't be able to PM it as this is your first post. If you'd like you can just post again saying "I'd like to PM" and then we can approve that and then you would be able to PM it.
UPDATE: objects.cache shared with techs

Yes, that is the service. I'll have the DB repair script run shortly. I'll let you know once I run it. Thanks

repair script has been run and completed successfully. What would you like me to try next? The alert i still sending every 10 minutes. Should I resave the service config and apply config again? Thanks -- tc

Thanks!
Let's truncate some tables next.
Code: Select all
mysql -u ndoutils -pn@gweb nagiosxi -e 'TRUNCATE TABLE xi_meta'
mysql -u ndoutils -pn@gweb nagiosxi -e 'TRUNCATE TABLE xi_events'
mysql -u ndoutils -pn@gweb nagiosxi -e 'TRUNCATE TABLE xi_eventqueue
After that, you can repair the db again.
Code: Select all
cd /usr/local/nagiosxi/scripts/
./repair_databases.sh

Just got back to this. We ran the truncate commands and the refresh and the service continues to send multiple notifications. What's next? Thanks -- Tom

Can you post or PM the output of this command. Thanks.
Code: Select all
ps -ef | head -1 && ps -ef | grep bin/nagios
If you see multiple nagios processes or not, please run kill the nagios process with these commands.
Code: Select all
service nagios stop
killall -9 nagios
service nagios start
Then let us know if notifications are correct.

Thanks very much for your help. I appreciate the timely responses.
We have resolved the problem and believe that the problem was caused by host/service/notification template inconsistencies. When we created a new service that did not use any templates with hosts and contacts that also did not use templates the single notification started working (i love this technical smoke and mirrors stuff
)
Thanks again for your help -- Tom
