Red Hat OpenShift API Management provides a limited number of API calls. The API request hard limits are set as part of your Red Hat OpenShift API Management purchase. You are alerted to ensure you do not exceed the set API usage hard limit. OpenShift API Management uses a tiered approach for alerting customers when the API usage is close to the hard limit, to ensure request calls are not rejected and service is not interrupted.

An email notification is sent to the email address provided during the OpenShift API Management installation. The email notification includes a link to the Grafana dashboard, which provides a visualization of your API usage.

A notification is sent in the following instances:

  • If API usage is between 80% and 90% for a period of 4 hours, a notificication is sent every 4 hours.

  • If API usage is between 90% and 95% for a period of 2 hours, a notification is sent every 2 hours.

  • If API usage is over 95% for a period of 30 minutes, a notification is sent every 30 minutes.
