Class StackdriverWriter

java.lang.Object

com.googlecode.jmxtrans.model.output.BaseOutputWriter

com.googlecode.jmxtrans.model.output.StackdriverWriter

All Implemented Interfaces:

OutputWriter

public class StackdriverWriter
extends BaseOutputWriter

Stackdriver implementation of the OutputWriter.

This implementation uses POST /v1/metrics HTTP API.

Settings:

• "url": Stackdriver server URL. Optional, default value: "https://custom-gateway.stackdriver.com/v1/custom".
• "token": Stackdriver API token. Mandatory
• "prefix": Prefix for the metric names. If present will be prepended to the metric name. Should be alphanumeric. Optional, shouldn't be used at the same time as source or detectInstance. Different way of namespacing.
• "source": Instance of the machine ID that the JMX data is being collected from. Optional.
• "detectInstance": Set to "AWS" if you want to detect the local AWS instance ID on startup. Optional.
• "timeoutInMillis": read timeout of the calls to Stackdriver HTTP API. Optional, default value: 1000.
• "enabled": flag to enable/disable the writer. Optional, default value: true.
