Struct HystrixSink

pub struct HystrixSink {
    pub num_buckets: i64,
}

Stats configuration proto schema for built-in envoy.stat_sinks.hystrix sink. The sink emits stats in text/event-stream <<https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events>> formatted stream for use by Hystrix dashboard <<https://github.com/Netflix-Skunkworks/hystrix-dashboard/wiki>.>

Note that only a single HystrixSink should be configured.

Streaming is started through an admin endpoint :http:get:/hystrix_event_stream. [#extension: envoy.stat_sinks.hystrix]

Fields

num_buckets: i64

The number of buckets the rolling statistical window is divided into.

Each time the sink is flushed, all relevant Envoy statistics are sampled and added to the rolling window (removing the oldest samples in the window in the process). The sink then outputs the aggregate statistics across the current rolling window to the event stream(s).

rolling_window(ms) = stats_flush_interval(ms) * num_of_buckets

fn clone(&self) -> HystrixSink

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HystrixSink

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for HystrixSink

fn default() -> Self

Returns the “default value” for a type.

impl Message for HystrixSink

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl Name for HystrixSink

const NAME: &'static str = "HystrixSink"

Simple name for this Message. This name is the same as it appears in the source .proto file, e.g. FooBar.

const PACKAGE: &'static str = "envoy.config.metrics.v3"

Package name this message type is contained in. They are domain-like and delimited by ., e.g. google.protobuf.

fn full_name() -> String

Fully-qualified unique name for this Message. It’s prefixed with the package name and names of any parent messages, e.g. google.rpc.BadRequest.FieldViolation. By default, this is the package name followed by the message name. Fully-qualified names must be unique within a domain of Type URLs.

fn type_url() -> String

Type URL for this Message, which by default is the full name with a leading slash, but may also include a leading domain name, e.g. type.googleapis.com/google.profile.Person. This can be used when serializing into the google.protobuf.Any type.

impl PartialEq for HystrixSink

fn eq(&self, other: &HystrixSink) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for HystrixSink

impl StructuralPartialEq for HystrixSink
