// [#protodoc-title: Injected resource]
// [#extension: envoy.resource_monitors.injected_resource]

// The injected resource monitor allows injecting a synthetic resource pressure into Envoy
// via a text file, which must contain a floating-point number in the range [0..1] representing
// the resource pressure and be updated atomically by a symbolic link swap.
// This is intended primarily for integration tests to force Envoy into an overloaded state.
