1) What downtime detection method are you using for the device(s) in question?

2) Change the cacti logging level to debug. Watch the log file for when the poller runs. Why did spine think the device(s) were falsely up?

downtime detection method: "SNMP" then i tried "SNMP And Ping" then "PING"

cacti logging level to debug: normal logging the cacti thinks the device is online and trying to send OID numbers.

Each time you made the change, you waited for a polling cycle, looked in the log to see how the device responded to Cacti's initial queries?

For SNMP, the device shows its uptime/system info on the top left corner in cacti?

For Ping, the device shows "Ping Results Host is alive"in the top left corner?
