JSON configuration for REST API flow control - PingIntelligence for APIs - 5.2

The following example shows the flow control-related definitions in an API JSON file:

{
 "api_metadata": {
 "protocol": "http",
 
 "flow_control": {
 "client_spike_threshold": "0/second",
 "server_connection_queueing" : false
 },
 "servers": [
 {
 "host": "127.0.0.1",
 "port": 8080,
 "server_spike_threshold": "100/second",
 "server_connection_quota": 20
 },
 {
 "host": "127.0.0.1",
 "port": 8081,
 "server_spike_threshold": "200/second",
 "server_connection_quota": 40
 }
 ]
 }
}

The flow control section includes definitions that apply globally across the API definition and include the client_spike_threshold and server_connection_queueing parameters. Server specific definitions include the server_spike_threshold and server_connection_quota parameters, which are configured on each individual server. The default is no flow control with all values set to 0.

You can specify different values for each server for server_connection_quota and server_spike_threshold.
