| FORM PARAMETER | DEFAULT | DESCRIPTION |
|---|---|---|
| config.minimum_latency_msec | 0 | This parameter describes the minimum latency (msec) to be added |
| config.maximum_latency_msec | 1000 | This parameter describes the maximum latency (msec) to be added |
| config.request_percentage | 50 | Percentage of requests which shall get the latency added |
| config.add_header | true | If set to true a header X-Kong-Random-Latency will be added with either the value of the added latency or none if random generator has chosen not to add a latency (see also config.request_percentage) |
