Let's say we have two gauges, *progress_current* and *progress_goal*. *progress_current* is gradually increasing until it eventually meets *progress_goal*.
How can we write an expression that will tell us the time in seconds until progress_current meets *progress_goal*? I have seen a bunch of examples for predicting when a disk will fill, but these all seem to rely on the assumption that a gauge is trending downwards, and we are predicting when it meets zero. Such as: time() - (node_filesystem_free_bytes{mountpoint="/"} / deriv(node_filesystem_free_bytes{mountpoint="/"}[4h]) < 0) In this case we want to predict it trending upwards until it reaches some other gauge target.
