On the dashboard, there are many charts that we can look at.
Which one would be the best to use in order to know when an additional instance will be needed to handle additional traffic?
Some possible ways I thought about :
- When the ‘Active instances’ line is about to get above the current number of ‘Billable instances’
- When ‘Milliseconds used per second’ is about to break over 1000
Would these be true?
Any other way?
App Engine will spin up a new instance (or make an idle instance active) whenever the pending MS (the amount of time a request has been waiting in the queue) has reached the value you specified in the billing settings. Unfortunately, there’s currently no graph that corresponds to that.
