Datadog

The dogstatsd adapter is designed to deliver Istio metric instances to alistening DataDog agent.

This adapter supports the metric template.

Params

Configuration parameter for the DataDog adapter. These params control how Mixer telemetry is transformed and sent to a dogstatsd agent.

The adapter assumes that a dogstatsd agent is running as a sidecar or at some other endpoint that the Mixer can reach.Any dimension that is a part of the metric is converted to a tag automatically. The configuration of the DataDog agent/daemon is outside the scope of the adapter.

FieldTypeDescriptionRequired
addressstringAddress of the dogstatsd server.Default: localhost:8125No
prefixstringPrefix to prepend to all metrics handled by the adapter. Metric “bar” with prefix “foo.” becomes “foo.bar” in DataDog. In order to make sure the metrics get populated into Datadog properly and avoid any billing issues, it’s important to leave the metric prefix to its default value of ‘istio.’Default: “istio.”No
bufferLengthint32Number of individual metrics to buffer before flushing metrics to the network. When buffered, metrics are flushed every 100ms or when the buffer is filled.When buffer is 0, metrics are not buffered.Default: 0No
globalTagsmap<string, string>Tags to add to every metric. “global”: “tag” becomes “global:tag” in DataDogDefault: []No
sampleRatedoubleChance that any particular metric is sampled when emitted; can take the range [0, 1].Default: 1No
metricsmap<string, MetricInfo>Map of a specific metric instance name -> info. If a metric’s instance name is not in the map then the metric will not be exported to DataDog.No

Params.MetricInfo

Describes how to represent this metric in DataDog

FieldTypeDescriptionRequired
namestringName of the metric in DataDogNo
typeTypeThe type of metricNo
tagsmap<string, string>Tags to add to the metric in addition to the dimensions. “tag”: “val” becomes “tag:val” in DataDogDefault: []No

Params.MetricInfo.Type

Describes the type of metric

UNKNOWN_TYPEDefault Unknown Type
COUNTERIncrements a DataDog counter
GAUGESets the new value of a DataDog gauge
DISTRIBUTIONDISTRIBUTION is converted to a Timing Histogram for metrics with a time unit and a Histogram for all other units
