# DataDog To enable the DataDog: ```toml tab="File" [tracing] [tracing.dataDog] ``` ```bash tab="CLI" --tracing --tracing.datadog ``` #### `localAgentHostPort` _Required, Default="127.0.0.1:8126"_ Local Agent Host Port instructs reporter to send spans to datadog-tracing-agent at this address. ```toml tab="File" [tracing] [tracing.dataDog] localAgentHostPort = "127.0.0.1:8126" ``` ```bash tab="CLI" --tracing --tracing.datadog.localAgentHostPort="127.0.0.1:8126" ``` #### `debug` _Optional, Default=false_ Enable DataDog debug. ```toml tab="File" [tracing] [tracing.dataDog] debug = true ``` ```bash tab="CLI" --tracing --tracing.datadog.debug=true ``` #### `globalTag` _Optional, Default=empty_ Apply shared tag in a form of Key:Value to all the traces. ```toml tab="File" [tracing] [tracing.dataDog] globalTag = "sample" ``` ```bash tab="CLI" --tracing --tracing.datadog.globalTag="sample" ``` #### `prioritySampling` _Optional, Default=false_ Enable priority sampling. When using distributed tracing, this option must be enabled in order to get all the parts of a distributed trace sampled. ```toml tab="File" [tracing] [tracing.dataDog] prioritySampling = true ``` ```bash tab="CLI" --tracing --tracing.datadog.prioritySampling=true ```
