Hi everybody!
I'm using "Total Network Monitor 1.1.3" on my Windows XP PC. Great product! :D

I have to monitor some Network devices (lets call one of them "Client A") in the same Network and I'm using the ICMP-Ping for this.
TNM sends a ping every 2 Minutes.
The problem is, sometimes the "Client A" is busy for 30sec and can not reply the ping in that time - but this is not a fault.
So the TNM probe gets red and gives me a alarm message. How can I set a timeout for that?
I thought, I can use the "timeout"-slider to send the ping again after the adjusted time - but I was wrong.
I tried to set the "retry count" to a higher number (10 or so) and TNM will ping again, but this doesn't work either.

Do you have any ideas how to solve the problem?

Thank you in advance!
Nico.

Neither timeout, nor retry count should be used for this purpose.
Timeout should be 1 or several seconds, and retry count should be 1-2 (no sense for more right now).
For this purpose you should use the option in the action (alarm): "N times in a row". For example, if you set N to 5, and the ping is sent each 2 minutes, then you will receive the alarm message only after 10 minutes. And if the host is down for 5 minutes (example), and then up again, you will not receive false messages.

I have somewhat the same problem and I try the solution above.  I have the Red and Green both on the same sensor.  The problem is even though I don't get the Red email / text, I still get the Green one.  I get it when the sensor comes back from being 50 % down.    The settings are N is set to 3 and 1 minute apart.  The timeout is set to 1 minutes.  Any ideas would be greatly appreciated !


Thanks

I thinks that timeout of 1 minute is too much for ping. Usually 1 second is enough, but you can set 5 or 10 seconds. The behaviour when the intervals are overlapping may be unexpected.

Also what is you retry count? Better set to 2 (default). "3 times in a row" with 1 minute interval is fine, but timeout should not be such long, as I've mentioned. You should get the red email when the device is offline for 3 minutes in such case.

Здравствуйте. У меня похожий вопрос. Есть ICMP монитор  с интервалом 1 мин и таймаутом 1 сек., есть действие, которое при получении 3 красных результатов пишет лог. проблема в том, что при получении, например 30 последовательных красных результатов в лог запишется 10 сообщений. Как можно сделать так, чтоб запись была только одна до смены результата на зеленый?

Hi turbo,

Disable the option "repeatedly" and that's all.
