In this case, I recommend to configure a "State Trigger" in the "notification trigger" tab of the Ping Sensor. In this case, you can configure the trigger so that you will receive a notification if the Sensor is "Down" and one notification if the Sensor is "Up" again.

Hi Thank you for your reply Mr.Mortiz

I set trigger as you said and set notification to send when machine goes "Down", But, when I restart the machine Ping Sensor is staying in "Up state" only. I am using PRTG version 20.3.60.1362. Before that, Its not sending notification from last 6 days. Before, It used to send notifications fine when machine restarts.

Hi there,

if the device is offline, the ping sensor shouldn't be able to ping the device. Please check if you use a 30s scanning interval. In addition, please check if you can manually ping the device during the restart.

When i restart machine and check the ping manually ... I see 3 to 5 "request timed out" messages, But the same time ping sensor showing "up state".

ping settings for server:

Ping Timeout(Sec): 1 Packet Size(Bytes): 32 Ping Method: Send multiple ping requests Ping Count: 1 Ping Delay(ms): 1

I suspect that the restart of the device is faster than the scanning interval of the Sensor. Pleas check the scanning interval.

Please note that any scanning interval below 30s is not supported. However it's possible to configure new scanning interval via "Setup > System Administration > Monitoring". Afterwards, you can select the scanning interval in your Sensor settings.
