how to get email alert from cacti management->device whenever unknown / down status

[raymondtong]

i get it updated to 1.2.27, but the testing device status still wrongly displayed as UP,
it should be down as I set it ping to a non-opened port,

any other things I could set wrong?

it is cacti issue. Use icmp ping instead of tcp ping. For monitoring opened ports you can use tcp port template. Template is somewhere in forums
