Hi,
if you are running server scripts (NXSL), you can use PostEvent function: https://wiki.netxms.org/wiki/NXSL:PostEvent
Another possible option is to set node's custom attribute in reaction for SYS_NODE_DOWN and create status poll hook script, which will check if node is down for certain amount of time and use PostEvent function to generate another event.
Best regards,
Victor
