Only a manager could find this useful. A metric is a statistic in the true sense of the word, i.e. it has a distribution is subject to random variation. In other words, looking at a metric every x days, is akin to flipping a coin and making a decision based on whether it came back heads or tails.

Surely that depends on exactly how much it has changed and how much variation is usually present. If a metric that has been 5 +/- 1 for years suddenly reads 500 after a new release, it might be worth looking into.
