Enumeration Type Documentation

HttpClientMetricsType

enum class Aws::Monitoring::HttpClientMetricsType

strong

Metrics definitions optional from HttpClient module inside AWS Sdk core.

Enumerator
DestinationIp
AcquireConnectionLatency	Requires the SDK to recognize that an existing connection was reused to make the request, contains the time interval (in milliseconds) between the construction of the http request and when a connection was successfully acquired from the connection pool.
ConnectionReused	Requires the SDK to recognize whether or not an existing connection was used to make the request, contains 1 if an existing connection was used to perform the http request; contains 0 if a new connection was opened to perform the http request.
ConnectLatency	Requires the SDK to recognize that a new connection was established to make the request, contains the time interval (in milliseconds) between the construction of the http request and when a connection was fully established. If the SDK is able to estimate this time despite not having a perfectly accurate callback for the specific event, then it should. For example, if the http client includes user-level data write functions that are guaranteed to be called shortly after connection establishment, then the first call could be used as a reasonable time marker for ConnectLatency
RequestLatency	Requires the SDK to be able to mark the point in time where the request starts transmission, contains the time interval (in milliseconds) between when the request begins transmission to the service and when a terminal error has occurred or the response has been parsed, excluding streaming payloads. Like ConnectLatency, if the SDK has access to an event that is a "close enough" marker in time, it should include this entry. The request here is a http level request, not a service level API request.
DnsLatency	Requires the SDK to have access to how long it took to perform DNS lookup, if it took place, contains the time (in milliseconds) it took to perform DNS lookup, during the Api Call attempt.
TcpLatency	Requires the SDK to have access to how long it took to establish the underlying Tcp/Ip connection used for the request, contains the time (in milliseconds) it took to fully establish the TCP/IP connection used to make the request attempt.
SslLatency	Requires the SDK to have access to how long it took to perform the SSL handshake for a secure request, contains the time (in milliseconds) it took to perform a SSL handshake over the established TCP/IP connection.
DownloadSpeed	Request the SDK to have access to the download speed in bytes per second for a request.
Throughput
UploadSpeed	Upload speed of the request in bytes per second.
Unknown	Unknow Metrics Type

Function Documentation

AddMonitoring()

AWS_CORE_API void Aws::Monitoring::AddMonitoring ( const std::vector< MonitoringFactoryCreateFunction > &  monitoringFactoryCreateFunctions)

Add monitoring using supplied factories

CleanupMonitoring()

AWS_CORE_API void Aws::Monitoring::CleanupMonitoring ( )

Clean up monitoring related global variables. This should be done first at shutdown, to avoid a race condition in testing whether the global Monitoring instance has been destructed.

GetHttpClientMetricNameByType()

AWS_CORE_API Aws::String Aws::Monitoring::GetHttpClientMetricNameByType ( HttpClientMetricsType  type)

GetHttpClientMetricTypeByName()

AWS_CORE_API HttpClientMetricsType Aws::Monitoring::GetHttpClientMetricTypeByName ( const Aws::String &  name)

InitMonitoring()

AWS_CORE_API void Aws::Monitoring::InitMonitoring ( const std::vector< MonitoringFactoryCreateFunction > &  monitoringFactoryCreateFunctions)

Init monitoring using supplied factories, monitoring can support multiple instances. We will try to (based on config resolution result) create a default client side monitoring listener instance defined in AWS SDK Core module. and create other instances from these factories. This function will be called during Aws::InitAPI call, argument is acquired from Aws::SDKOptions->MonitoringOptions

OnFinish()

void Aws::Monitoring::OnFinish ( const Aws::String &  serviceName,

const Aws::String &  requestName,

const std::shared_ptr< const Aws::Http::HttpRequest > &  request,

const Aws::Vector< void * > &  contexts 

)

Wrapper function of OnFinish defined by all monitoring instances

OnRequestFailed()

void Aws::Monitoring::OnRequestFailed ( const Aws::String &  serviceName,

const Aws::String &  requestName,

const std::shared_ptr< const Aws::Http::HttpRequest > &  request,

OnRequestRetry()

void Aws::Monitoring::OnRequestRetry ( const Aws::String &  serviceName,

const Aws::String &  requestName,

const std::shared_ptr< const Aws::Http::HttpRequest > &  request,

const Aws::Vector< void * > &  contexts 

)
