<span style=" font-family:'Courier New'; font-size: 9pt;">A few thoughts - though not exactly an answer to your question:<br>
<br>
1) I'm often too dense to grok out why more elaborate triggers don't work the way I want, and your falls into that category. But this seems, IMO, to be a very common problem. So, my solution: Make them simpler. Way simpler. [It's kind of like fancy regexs - I think I'm *so* clever and pat myself on the back. But then I actually run that regex against more real-world data, and well, it doesn't end pretty... So, I usually go back to - simpler is better, unless it's impossible to solve otherwise.] <br>
<br>
2) In your case - do you really want to wait 75 minutes to find out a connection is completely down? [Or perhaps you have another trigger that does that.] But even if you do - this is just my opinion - but loss greater than 10% over more than 10-15 minutes is a sign of a _serious_ problem. So, I have simple triggers that let me know if I have even modest loss over fairly short periods of time. Yes, that can increase the number of alerts you see - but if you've got a connection with that many problems, you need to address the underlying problem, not just chirp at you about it less often.<br>
<br>
3) Yes, at first glance, your pattern appears right. However, I think the *25* means *up to* 25 samples. [0-25]<br>
So, a 10% loss, followed by another 10% loss the very next sample will match a pattern of: >10%,*25*,>10% or it will also match <br>
A 10% loss, followed by another 10% loss with 1-25 samples between them with <10% loss.<br>
<br>
So your example will also trigger with 4 subsequent samples of >10% loss each [i.e. over 4 sample periods]. It would also trigger in the conditions you envision - (1) >10% loss sample, and then another > 10% loss, 25 samples later, and another 25 samples later etc... <br>
<br>
Again, I think less fancy is more likely to produce a result that's still useful and a lot less trouble to test and verify it works in the conditions you envision.<br>

<span style=" color: #800000;"><b>RdH> Hi team<br>
<br>
RdH> I hope you are doing great today?<br>
<br>
RdH> what a great tool! Love to run it on my RBp2 and monitor the<br>
RdH> internet connection! I have a small question but i can’t solve it<br>
RdH> myself would you try to help me?<br>
<br>
RdH> The goal is to have an alert when the internetline is<br>
RdH> experiencing packetloss, but for a longer time not on every<br>
RdH> glitch. Im using FPingnormal with a step of 180 (means 3 minutus) <br>
<br>
RdH> The loss pattern i defined is like :<br>
RdH> 10%,*25*,>10%,*25*,>10%,*25*,>10% which means based on the how<br>
RdH> to’s provided on the website: Take 25 samples (which is 25*3<br>
RdH> minutes) so if the packetloss exists from start -> 75 minutes<br>
RdH> later still>10% -> 75 minutes later still >10% and another 75<br>
RdH> minutes later still >10% send out an email.<br>
<br>
RdH> But it send out an email almost directly, please see the<br>
RdH> screenshots where the packets loss starts and when i received the<br>
RdH> email, that timeframe is not even close to 75 minutes but more like a few minutes.<br>
<br>
RdH> Could you advise how to make the packetloss alarm more reliable<br>
RdH> where it last for at least 1 hour before sending out the email?<br>
<br>
RdH> Many thanks! Cheers Rob<br>
<br>
RdH> how the system works now (screenshots where to big)<br>
<br>
RdH> -packetloss started about 07:40 stable around 07:55 and started again 08:03<br>
RdH> -email alarm received around 08:07 after the second block of packets loss<br>
RdH> -email cleared received after 3 minutes around 08:10<br>
