List the metric values for a load test run.

public virtual Azure.Pageable<BinaryData> GetMetrics (string testRunId, string metricName, string metricNamespace, string timespan, Azure.Core.RequestContent content = default, string aggregation = default, string interval = default, Azure.RequestContext context = default);

abstract member GetMetrics : string * string * string * string * Azure.Core.RequestContent * string * string * Azure.RequestContext -> Azure.Pageable<BinaryData>
override this.GetMetrics : string * string * string * string * Azure.Core.RequestContent * string * string * Azure.RequestContext -> Azure.Pageable<BinaryData>

Public Overridable Function GetMetrics (testRunId As String, metricName As String, metricNamespace As String, timespan As String, Optional content As RequestContent = Nothing, Optional aggregation As String = Nothing, Optional interval As String = Nothing, Optional context As RequestContext = Nothing) As Pageable(Of BinaryData)

Parameters

testRunId

String

Unique name for the load test run, must contain only lower-case alphabetic, numeric, underscore or hyphen characters.

metricName

String

Metric name.

metricNamespace

String

Metric namespace to query metric definitions for.

timespan

String

The timespan of the query. It is a string with the following format 'startDateTime_ISO/endDateTime_ISO'.

content

RequestContent

The content to send as the body of the request. Details of the request body schema are in the Remarks section below.

aggregation

String

The aggregation.

interval

String

The interval (i.e. timegrain) of the query. Allowed values: "PT5S" | "PT10S" | "PT1M" | "PT5M" | "PT1H".

context

RequestContext

The request context, which can override default behaviors of the client pipeline on a per-call basis.

Returns

Pageable<BinaryData>

The Pageable<T> from the service containing a list of BinaryData objects. Details of the body schema for each item in the collection are in the Remarks section below.

Exceptions

ArgumentNullException

testRunId, metricName, metricNamespace or timespan is null.

ArgumentException

testRunId is an empty string, and was expected to be non-empty.

RequestFailedException

Service returned a non-success status code.

Examples

This sample shows how to call GetMetrics with required parameters and parse the result.

var credential = new DefaultAzureCredential();
var endpoint = new Uri("<https://my-service.azure.com>");
var client = new LoadTestRunClient(endpoint, credential);

var data = new {};

foreach (var data in client.GetMetrics("<testRunId>", "<metricname>", "<metricNamespace>", "<timespan>", RequestContent.Create(data)))
{
    JsonElement result = JsonDocument.Parse(data.ToStream()).RootElement;
    Console.WriteLine(result.ToString());
}

This sample shows how to call GetMetrics with all parameters and request content, and how to parse the result.

var credential = new DefaultAzureCredential();
var endpoint = new Uri("<https://my-service.azure.com>");
var client = new LoadTestRunClient(endpoint, credential);

var data = new {
    filters = new[] {
        new {
            name = "<name>",
            values = new[] {
                "<String>"
            },
        }
    },
};

foreach (var data in client.GetMetrics("<testRunId>", "<metricname>", "<metricNamespace>", "<timespan>", RequestContent.Create(data), "<aggregation>", "<interval>"))
{
    JsonElement result = JsonDocument.Parse(data.ToStream()).RootElement;
    Console.WriteLine(result.GetProperty("data")[0].GetProperty("timestamp").ToString());
    Console.WriteLine(result.GetProperty("data")[0].GetProperty("value").ToString());
    Console.WriteLine(result.GetProperty("dimensionValues")[0].GetProperty("name").ToString());
    Console.WriteLine(result.GetProperty("dimensionValues")[0].GetProperty("value").ToString());
}

Remarks

Below is the JSON schema for the request payload and one item in the pageable response.

Request Body:

Schema for MetricRequestPayload:

{
  filters: [
    {
      name: string, # Optional. The dimension name
      values: [string], # Optional. The dimension values. Maximum values can be 20.
    }
  ], # Optional. Get metrics for specific dimension values. Example: Metric contains dimension like SamplerName, Error. To retrieve all the time series data where SamplerName is equals to HTTPRequest1 or HTTPRequest2, the DimensionFilter value will be {"SamplerName", ["HTTPRequest1", "HTTPRequest2"}
}

Response Body:

Schema for MetricsValue:

{
  data: [
    {
      timestamp: string, # Optional. The timestamp for the metric value in ISO 8601 format.
      value: number, # Optional. The metric value.
    }
  ], # Optional. An array of data points representing the metric values.
  dimensionValues: [
    {
      name: string, # Optional. The name of the dimension.
      value: string, # Optional. The value of the dimension.
    }
  ], # Optional. The dimension values 
}
