Forecasting disk usage - trigger doesn't clear when I add more disk space

[Nic65535]

I am trying to use a forecast trigger to notify me when I am going to have less than 20% free disk space on a disk in 5 days time based on the last 5d of data:

{vfs.fs.size[C:,pfree].forecast(5d,,5d,,min)}<20

This works fine as disk space is consumed but continues to trigger when I add additional disk space that would fix the problem.

This makes me think I don't understand how forecast actually works.

Can anyone suggest either a correct trigger and/or recovery expression or some further documentation on how the forecast function is actually supposed to work.

TIA

Hi spiltek,

It is 20% I want hence using the pfree and I added enough disk space to meet the 20% criteria. My point is that the trigger remained (although it did clear overnight). So is there some sort of delay on forecast?

Thanks

Nic
