FLAPPING, do not want to get too many notification

[bisana]

Hi All,
I am preparing a demo, my intention was to send notification when the network link input speed goes less than 1Mb for the last 10 minutes, which I did and I was getting notification, but it keeps on sending the notification, which did not go well with the evaluation team
Initially my trigger was
{Demo-ISP-Router:ISP20MbDemoInput.min(10)}<1M

Then to solve the issue of too much notification, I found that I have to use flapping way
so I created a AND condition with the trigger status and the min value, but this also not helping out
the modified condition is
{Demo-ISP-Router:ISP20MbDemoInput.min(10)}<1M and {TRIGGER.VALUE}=0

But this also I did not find any much success.
Like to request for guidance and feedback, how could I make the trigger work better
Thanks
Joseph John

Yeah, it would be great if we could set what notifications that we want to avoid getting to many.

Test:

{Demo-ISP-Router:ISP20MbDemoInput.min(10m)}<1M

Your homework is to find what is difference between min(10) and min(10m) :-)

Thanks for the links and guidance.

I will find out the difference which u had asked me to do,

Let me think here, what do I want. I want less notification. Ok if the trigger is active minimum bandwidth less than 1 Mb, I get a problem notification and it been in the problem till the last value of bandwidth less than 1.5Mb. In this way I will be getting fewer notification than previous one. The following is what I managed to do

({TRIGGER.VALUE}=0 and {Demo-ISP-Router:ISP20MbDemoInput.min(10m)}<1M ) 
or 
({TRIGGER.VALUE}=1 and {Demo-ISP-Router:ISP20MbDemoInput.min(10m)}<1.5M)

I applied it and waiting on the parameters to get active.
