I would like to receive notifications for machine restarts using ping sensor.
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 18.104.22.1682. Before that, Its not sending notification from last 6 days. Before, It used to send notifications fine when machine restarts.
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.
Hi, Scanning interval already set to 30 seconds. thats the minimum i see. is there any chance to set it for 10 sec?.-Than you.
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.
If I set to 10 sec and change the scanning interval in sensor settings.. Shall I still the alerts..?
As soon as the Sensors goes down and the configured time in the notification trigger is passed, a notification will be triggered.
Thank you for your reply. You said "5 sec" scanning does not support. Is it in PRTG free version and PRTG paid version too?
I set the ping sensor scanning interval to "10 sec". And, I will check that will it send alerts on production systems when they restarts as I have scheduled downtime this weekend.
I will also check that the restart of the devices are faster than the scanning interval of the Sensor. -Thank you.
Is there any other way to check and get notifications if machine reboots?
Thank you once again.
A scanning interval of 5sec is not support, but possible. Therefore you can try to use the scanning interval. If you want to be notified very fast, you can also decrease the notification trigger time to 10s or less. E.g. "If the Sensor is down for 5sec, trigger notification XXXXX"
This is the best way to monitor a restart
Current my ping settings:
Ping Timeout : 2 sec Ping Packet Size : 32 bytes Ping Method : Send Multiple Ping Requests Ping Count : 5 Ping Delay : 5 msec Scanning Interval : 10 sec
If a Sensor Query Fails : Set Sensor to Down Immediately
Current my Notification Trigger Settings:
State Trigger: When sensor state is "DOWN" for at least "3 seconds", perform "Send Email alert" When sensor state is "DOWN" for at least "300 seconds", perform "No Email alert" When sensor leaves down state after a notification was triggered, perform "Send Email alert"
With all the above settings ;; Still I am failing to get " System restart alert".
According to these settings, you should receive a notification. If you don't see "Notification Trigger acitvated" in the "log" tab of your Ping Sensor, please wirte an email to "[email protected]" with the ID "PAE2017950" in the subject for further troubleshooting.
