Method Details

requests

public long requests()

Number of HTTP requests attempted.

responses

public long responses()

Number of HTTP responses received.

successes

public long successes()

Number of 200 OK HTTP responses received.

statsByCode

public Map<Integer,OperationStats.Response> statsByCode()

Statistics per response code.

duration

public Duration duration()

response

public Optional<OperationStats.Response> response(int code)

Statistics for the given code.

exceptions

public long exceptions()

Number of exceptions (instead of responses).

inflight

public long inflight()

Number of attempted requests which haven't yielded a response or exception yet.

averageLatencyMillis

public long averageLatencyMillis()

Average request-response latency, or -1.

minLatencyMillis

public long minLatencyMillis()

Minimum request-response latency, or -1.

maxLatencyMillis

public long maxLatencyMillis()

Maximum request-response latency, or -1.

bytesSent

public long bytesSent()

Number of bytes sent, for HTTP requests with a response.

bytesReceived

public long bytesReceived()

Number of bytes received in HTTP responses.

operationAverageLatencyMillis

public long operationAverageLatencyMillis()

Operation latency is the time from the initial HTTP request is sent until the operation was successfully completed as observed by the client. Time spent on retrying the request will be included. Operations that eventually failed are not included.

Returns:

average latency in milliseconds

operationMinLatencyMillis

public long operationMinLatencyMillis()

Returns:

minimum latency as milliseconds

• operationAverageLatencyMillis()

operationMaxLatencyMillis

public long operationMaxLatencyMillis()

Returns:

max latency as milliseconds

See Also:

• operationAverageLatencyMillis()

toString

public String toString()

Overrides:

toString in class Object
