NetXMS Support Forum

Hello everybody!

Another problem I do have with system notifications on e-mail.
The question is - how can I configure Event Processing Policy for example to send email notification if node is down but not before there are at least 3 polls which gives me "node down" status?

When there is huge traffic on the network, sometimes some switches or servers does not answer for poll from NetXMS server even if they are pinging from my workstation. To prevent chaos in our office, I would like to be sure that if I do get sms/email notification, it really means that there is some real problem on the network, not just wrong poll.

PS. Also adding rule such as "Do not send notification more then once if the node is down" which would rearm after node is alive again, would be really helpful 

Thanks!

I tried to use threshold in DCI configuration. Activation of event "sys_node_down" if the sum of last 5 polls would be 20 (if value of 4 means "offline") or last 5 polls are equal to 4. But still mail notification is being sent as soon as netxms server notices something being offline. What am I doing wrong? How to activate those thresholds?

If you use the default "SYS_NODE_EVENT", this is bound to happen.
Define your own event "NODE_REALLY_DOWN" or whatever, link it to the threshold and the event processing policy.
