Nagios service restarts and send duplicate alerts

Postby Johnsmit » Tue Dec 04, 2018 2:28 pm

Hi,

we have a hot standby failover nagiosXI with 5.5.6 runing. we stopped nagios service to stop duplicate monitoring but today the nagios service has been started by audit manager and sending duplicate alerts. for every alert it keeps sending 4 alerts at the same time?


here is what i found on logs, who is this auditmanager, why he wakes up nagios? and why am getting 4 alerts instead one alert from filover server.

Hello, @Johnsmit. Are you using some kind of software to transfer backups from the primary XI server to the backup XI server? The restore_xi script contains the command that starts the Nagios process.
Can you also run ps -ef on the backup XI server and attach the output in a text file?

It looks like the restart is triggered by a McAfee program:

https://kc.mcafee.com/corporate/index?p ... cale=en_US

The 4 messages are being sent to 4 different contacts - ismail,joseph,mohan,robyn. This logging is expected. You can modify the service check and remove contacts if you wish to not send to all 4 people.

Hi, here is the output of ps -ef on backup server. I don't use any software to transfer backups from primary to secondary. wqe have master-master replication between databases and cron job to sync files.

Thanks,

The logging is fine to send 4 alerts to 4 persons, but each person is getting 4 alerts for a single service at a time.

The ps output does show McAfee software on the machine it looks like the question of where those messages are are coming from is confirmed.

I can't think of a reason why it would send 4 emails - do you see 4 notification messages for each account if you look in /usr/local/nagios/var/nagios.log? What do your mail settings look like under Admin > System Config > Manage Email Setting ? Do you get 4 emails if you use the "send a test email" button on that screen? Does the email server show 4 emails coming from the XI machine and can we confirm that the duplication isn't happening elsewhere?

why am i getting 2 correction alerts for one notification. Correction out of 4 alerts 2 are from primary and 2 are from secondary.
Do i need to correct any settings in CCM so as to get one correction alert for 1 hard state notification.


Thanks,
Johnsmit

There may be duplicate notification methods selected. Edit the user(s) under Configure > Core Config Manager > Alerts > Contacts > *select contact* > Alert Settings > Manage Host Notification Commands & Manage Service Notification Commands. Usually there should only be one command for each - xi_host_notification_handler & xi_service_notification_handler respectively.

Still, am getting 2 correction alerts for a single notification, even after the changes made as you suggested. Is there any another setting to setup.

Thanks,
