Increasing trigger severity as free disk space reduces

[Onge]

I am trying to create increasing trigger severities as disk space gets lower and lower but am struggling a little, hope someone can help.

I currently have 3 triggers configured for free disk space:

less than 10GB = average
less than 5GB = high
less than 1GB = disaster

This works but means if a host has less than 1GB we have 3 triggers showing on our dashboard.

I would like the most severe trigger to show by itself ideally.

I have thought about creating 3 triggers as below:

less than 10GB and greater than or equal to 5GB = average
less than 5GB and greater than or equal to 1GB = high
less than 1GB = disaster

But as free disk space decreases you'd receive an OK for the 10GB and then a problem for the 5GB and I think this would be confusing.

Is there a way to get alerts for less than 10GB and then if the free disk space reduced below 5GB free, to also get an alert for less than 5GB whilst at the same time closing the less than 10GB alert but not notifying with an OK?
If the free space then went back above 5GB but still less than 10GB it should open another 10GB trigger.

I would like this to apply to the less than 1GB free alert as well.

Would dependencies allow this to work?

Any help appreciated.

Thank you Hamardaban - in my head I couldn't envision how dependencies could solve this, but can confirm it works as described above.

I have applied this to my remaining hard drive space alerts and remaining RAM alerts as well.

The snip below shows what I ended up with.
