Zabbix and different levels of the same alert

[StefanK]

I have two alerts for swap space remaining. One at 20% and one at 10%

The issue I'm having is that once it reaches the 10% threshold both alerts are firing at the same time. How can i make it so that when the 10% threshold is reached the 20% threshold alert is resolved.
I have tried the recovery expression but the issue is that the original expression never resolves so it does not work

Trigger dependency, the 10% depends on the 20%. (I think, sometimes I get them backwards)

Edit: Yea, you're doing space remaining, so that's backwards. The less critical trigger depends on the more critical trigger, no matter what the numbers

Yes. It is set up this way. The warning trigger is set at 20% space remaining and fires fine. When the critical trigger fires at 10% remaining the old one still stays open and sends mails

You probably have expression like "swap<20%" and "swap<10%" ?? Of course both of them are true, if your swap space is something like 8%...
change first one to "swap<20% and swap>10%" in that case it turns false, if your swap size is less than 10%...
