Query Explanation

The rule examines the free bytes on each non‑temporary filesystem, uses predict_linear over the past 3 h to forecast the available space 24 h into the future, and fires when that forecast is ≤ 0 while the current free space is still > 0. In other words, it alerts when the recent usage rate predicts the filesystem will run out of space within the next day, even though it hasn't yet.
