# API DoS and DDoS threshold

**API DoS and DDoS threshold 11**

API Flow Control reports on API Security Enforcer configured flow control thresholds that are exceeded. The reporting is done on the following parameters:

* Client Spike – inbound client traffic rate

* Server Spike – aggregate traffic to an API service

* Connection Queued – connection requests queued due to server at concurrent connection limit

* Bytes-in Spike – WebSocket aggregate inbound traffic exceeds limit

* Bytes-out Spike - WebSocket aggregate outbound traffic exceeds limit

For a specified API, the flow control API provides a summary of thresholds exceeded and detailed reporting on each flow control threshold exceeded:
