Dear,
is it somehow possible or planned in Dataminer to temporarily disable mail sending?
Because some Correlation rules will be triggered after a DMA maintenance. (Workaround would be to uncheck all rules, but maybe there is a global parameter ?)

As this question has now been inactive for a long time and there has been no further reaction from you, I will now close it. If you want more information about this, could you post a new question?
Hi Cedric,
Maybe an option could be disabling the alarms that trigger the correlation rules?
You could disable an alarm template for a period of time: Scheduling an alarm template.
Hope it helps.
Thanks for your idea. Yes, this seems also to be a possibility by selecting alarm templates one by one. Like I could also disable correlation rules one by one.
I am thinking of something more global (stop all outgoing mails)
Regards
Unfortunately there is not a standard method for that. But I’m wondering if anybody in the community could advise Cedric further on how this could still be accomplished. Thinking out loud:
– The correlation rules could probably be updated to include also a condition linked to one metric that could be set to YES/NO. So that setting it to NO would prevent the rules from firing off. Disadvantages I see for this are 1) Cedric would have to update all correlation rules with that extra condition, and 2) one would have to have somewhere an element with a metric probably to hold that YES/NO value, as correlation rules can only consider element metrics. Correct?
– would it be conceivable to write an automation script that iterates across the correlation rules, and disables / enables them? Potentially risk I see there is that the automation should remember which ones where toggled (as you do not want to activate a correlation rule that was disable in the first place and was hence not active).
– would it be conceivable to intervene on the level of the configuration of the e-mail notifications, e.g. to boot without mail server reference (or would that just buffer all notification mails and then they would still go out if the mail server configuration is reinstated)?
– I was also wondering Cedric why you have those transient / false triggers. Those are each time at a restart? Could an update of the correlation rule definition not prevent what you see?
– I was also wondering if the Alarm Storm Prevention on Email notifications could help mitigating this. But not sure if this only acts on Email alerts, and maybe not Email notifications that originate from a correlation rule. Not sure if somebody knows about this? This Alarm Storm Prevention could then maybe be set very low during a reboot cycle? https://docs.dataminer.services/user-guide/Advanced_Functionality/Security/Basic_security_configuration/Configuring_user_notifications/Configuring_alarm_storm_prevention_for_notifications.html#configuring-alarm-storm-settings-on-system-level
Hi Cédric,
Since ARTE has only one DMA, maybe just temporarily blocking the SMTP traffic on the server’s firewall would be a feasible and simple option.
I see that this question has been inactive for some time. Do you still need assistance with this? If not, could you select the best answer to indicate that the question is resolved?
