StatsD

The statsd adapter enables Istio to deliver metric data to a StatsD monitoring backend.

This adapter supports the metric template.

Params

Configuration format for the statsd adapter.

FieldTypeDescriptionRequired
addressstring

Address of the statsd server, e.g. localhost:8125

No
prefixstring

Metric prefix, do not specify for no prefix

No
flushDurationDuration

FlushDuration controls the maximum amount of time between sending metrics to the statsd collection server. Metrics are reported when either flushbytes is full or flushduration time has elapsed since the last report.

No
flushBytesint32

Maximum UDP packet size to send; if not specified defaults to 512 bytes. If the statsd server is running on the same (private) network 1432 bytes is recommended for better performance.

No
samplingRatefloat

Chance that any particular metric is sampled when incremented; can take the range [0, 1], defaults to 1 if unspecified.

No
metricsmap<string, MetricInfo>

Map of metric name -> info. If a metric’s name is not in the map then the metric will not be exported to statsd.

No

Params.MetricInfo

Describes how to represent this metric in statsd

FieldTypeDescriptionRequired
typeTypeNo
nameTemplatestring

The template will be filled with values from the metric’s labels and the resulting string will be used as the statsd metric name. This allows easier creation of statsd metrics like action_name-response_code. The template strings must conform to go’s text/template syntax. For the example of action_name-response_code, we use the template: {{.apiMethod}}-{{.responseCode}}

If name_template is the empty string the Istio metric name will be used for statsd metric’s name.

No

Params.MetricInfo.Type

The type of metric.
