Is there any way to limit the number of email alerts in a short time?

[vic]

I have an email alert for critical things that goes to an SMS account.

The problem is that sometimes the zabbix server in the data center sometimes goes offline for inbound (usually DDoS) but can still send emails. So I end up getting a whole bunch of SMS messages one after another for each server the Zabbix server monitors saying they are all offline. Even if the zabbix server is offline in and out it will still send a bunch once it comes back for all the back to normal alerts.

Is there a way to limit them so that I only get 1 if there are a bunch that try go out within say 1 minute of each other? Or maybe some way for the Zabbix server to intelligently determine that is doesn't have a network connection and therefore suppress alerts of false positives.

Hi,

In your case one option would be trigger dependencies.

https://www.zabbix.com/documentation/2.4/manual/config/triggers/dependencies

You have to configure am item which checks if Zabbix server is online and trigger if you have connectivity issues. Then you send one SMS message but all other triggers you set that they depend on this one Zabbix online trigger. In case Zabbix will be offline, other triggers will not fire.

Thanks so much. I think that could work. I just need to think of a way to determine the loss of network connectivity to trip that trigger. First thing that comes to mind is by checking google nameservers or a dns query check or maybe their landing page
