Datadog

The dogstatsd adapter is designed to deliver Istio metric instances to a listening 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
addressstring

Address of the dogstatsd server. Default: localhost:8125

No
prefixstring

Prefix 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
bufferLengthint32

Number 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: 0

No
globalTagsmap<string, string>

Tags to add to every metric. “global”: “tag” becomes “global:tag” in DataDog Default: []

No
sampleRatedouble

Chance that any particular metric is sampled when emitted; can take the range [0, 1]. Default: 1

No
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
namestring

Name of the metric in DataDog

No
typeType

The type of metric

No
tagsmap<string, string>

Tags to add to the metric in addition to the dimensions. “tag”: “val” becomes “tag:val” in DataDog Default: []

No

Params.MetricInfo.Type

Describes the type of metric

NameDescription
UNKNOWN_TYPE

Default Unknown Type

COUNTER

Increments a DataDog counter

GAUGE

Sets the new value of a DataDog gauge

DISTRIBUTION

DISTRIBUTION is converted to a Timing Histogram for metrics with a time unit and a Histogram for all other units
