title: Where to find the number of active concurrent invocations in Google Cloud Functions
body: <p>I am looking for a way to see how <strong>many concurrent invocations</strong> there are active at any point in time, e.g. in a minute range. I am looking for this as I received the error:</p>
  
  <blockquote>
    <p>Forbidden: 403 Exceeded rate limits: too many concurrent queries for
    this project_and_region. For more information, see
    <a href="https://cloud.google.com/bigquery/" rel="nofollow noreferrer">https://cloud.google.com/bigquery/</a></p>
  </blockquote>
  
  <p>The quotas are listed here: <a href="https://cloud.google.com/functions/quotas" rel="nofollow noreferrer">https://cloud.google.com/functions/quotas</a></p>
  
  <p>I am fine with having quotas, but I would like to see this number in a chart. Where can I find this?</p>
