# Datadog
To enable the Datadog tracer:
```yaml tab="File (YAML)"
tracing:
datadog: {}
```
```toml tab="File (TOML)"
[tracing]
[tracing.datadog]
```
```bash tab="CLI"
--tracing.datadog=true
```
#### `localAgentHostPort`
_Required, Default="127.0.0.1:8126"_
Local Agent Host Port instructs the reporter to send spans to the Datadog Agent at this address (host:port).
```yaml tab="File (YAML)"
tracing:
datadog:
localAgentHostPort: 127.0.0.1:8126
```
```toml tab="File (TOML)"
[tracing]
[tracing.datadog]
localAgentHostPort = "127.0.0.1:8126"
```
```bash tab="CLI"
--tracing.datadog.localAgentHostPort=127.0.0.1:8126
```
#### `debug`
_Optional, Default=false_
Enables Datadog debug.
```yaml tab="File (YAML)"
tracing:
datadog:
debug: true
```
```toml tab="File (TOML)"
[tracing]
[tracing.datadog]
debug = true
```
```bash tab="CLI"
--tracing.datadog.debug=true
```
#### `globalTag`
_Optional, Default=empty_
Applies a shared key:value tag on all spans.
```yaml tab="File (YAML)"
tracing:
datadog:
globalTag: sample
```
```toml tab="File (TOML)"
[tracing]
[tracing.datadog]
globalTag = "sample"
```
```bash tab="CLI"
--tracing.datadog.globalTag=sample
```
#### `prioritySampling`
_Optional, Default=false_
Enables priority sampling.
When using distributed tracing,
this option must be enabled in order to get all the parts of a distributed trace sampled.
```yaml tab="File (YAML)"
tracing:
datadog:
prioritySampling: true
```
```toml tab="File (TOML)"
[tracing]
[tracing.datadog]
prioritySampling = true
```
```bash tab="CLI"
--tracing.datadog.prioritySampling=true
```
