Detect a flapping service

[[email protected]]

I have found a lot of information on the web and in forums about how to detect flapping in checks using Hysteresis. However I specifically want to check if an item check IS flapping and get an alert.
I.e. if an item value goes above and below the trigger threshold multiple times in a certain time period, I want to get an alert.
Is there any way to do this?
Specifically very usefull in detecting a flapping service.

For example, trigger with condition "trigger change state at least 1 time in 2 min. during 6 min."
{your_item.count(2m,{$THRESHOLD},gt)}>0 and {your_item.count(2m,{$THRESHOLD},le)}>0
and {your_item.count(2m,{$THRESHOLD},gt,2m)}>0 and {your_item.count(2m,{$THRESHOLD},le,2m)}>0
and {your_item.count(2m,{$THRESHOLD},gt,4m)}>0 and {your_item.count(2m,{$THRESHOLD},le,4m)}>0

That's a nice solution.
I was hoping I could do something like "flapped 10 times in the last 24 hours", but your solution comes close to that.

Thanks very much.

This solution is more elegant: https://www.zabbix.com/forum/zabbix-...period-of-time

It uses a "Simple change" pre-processing to detect transitions and then you can count transitions using a trigger that looks like "count(24h,1) > 10"
