StatsD

阅读大约需要 2 分钟

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.

Field	Type	Description	Required
`address`	`string`	Address of the statsd server, e.g. localhost:8125	No
`prefix`	`string`	Metric prefix, do not specify for no prefix	No
`flushDuration`	`Duration`	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
`flushBytes`	`int32`	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
`samplingRate`	`float`	Chance that any particular metric is sampled when incremented; can take the range [0, 1], defaults to 1 if unspecified.	No
`metrics`	`map<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

Field Type Description Required

type Type No

Field	Type	Description	Required
`type`	`Type`		No
`nameTemplate`	`string`	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

nameTemplate

string

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.

Params.MetricInfo.Type

The type of metric.

Name	Description
`UNKNOWN`
`COUNTER`
`GAUGE`
`DISTRIBUTION`
