Key exhaustion looks at how fast a key is burning through its period limit and warns you when it’s projected to run out within the window you set. Use it when you want lead time to raise the limit, rotate the key, or investigate — before the key actually gets capped and starts rejecting requests.

​
When to use it

  • You set period limits on keys and want a heads-up before they’re hit.
  • A key’s burn rate jumped and you want to know before it runs dry.
  • Pairs well with key limit — exhaustion forecasts, key limit fires the moment usage actually crosses your percentage threshold.
Keys without a period limit are skipped — there’s nothing to forecast against.
