Not so long ago, I was writing about measuring Apps Script function performance, in particular those offered as part of the environment by Google. As add-ons get more complex and we rely more on other APIs that we have no control over, measuring how much we are making the user wait becomes important. Why poor man’s metrics? Because implementing them will cost nothing. But we are going to pay through hacks here and there to get a nice dashboard of metrics for our add-ons.
