  - HTTP_CLIENT_SENT_BYTES
```
public static final Measure.MeasureLong HTTP_CLIENT_SENT_BYTES
```
    Measure for the client-side total bytes sent in request body (not including headers). This is uncompressed bytes.
    
    Since:
    
    0.13
  - HTTP_CLIENT_RECEIVED_BYTES
```
public static final Measure.MeasureLong HTTP_CLIENT_RECEIVED_BYTES
```
    Measure for the client-side total bytes received in response bodies (not including headers but including error responses with bodies). Should be measured from actual bytes received and read, not the value of the Content-Length header. This is uncompressed bytes. Responses with no body should record 0 for this value.
    
    Since:
    
    0.13
  - HTTP_CLIENT_ROUNDTRIP_LATENCY
```
public static final Measure.MeasureDouble HTTP_CLIENT_ROUNDTRIP_LATENCY
```
    Measure for the client-side time between first byte of request headers sent to last byte of response received, or terminal error.
    
    Since:
    
    0.13
  - HTTP_SERVER_RECEIVED_BYTES
```
public static final Measure.MeasureLong HTTP_SERVER_RECEIVED_BYTES
```
    Measure for the server-side total bytes received in request body (not including headers). This is uncompressed bytes.
    
    Since:
    
    0.13
  - HTTP_SERVER_SENT_BYTES
```
public static final Measure.MeasureLong HTTP_SERVER_SENT_BYTES
```
    Measure for the server-side total bytes sent in response bodies (not including headers but including error responses with bodies). Should be measured from actual bytes written and sent, not the value of the Content-Length header. This is uncompressed bytes. Responses with no body should record 0 for this value.
    
    Since:
    
    0.13
  - HTTP_SERVER_LATENCY
```
public static final Measure.MeasureDouble HTTP_SERVER_LATENCY
```
    Measure for the server-side time between first byte of request headers received to last byte of response sent, or terminal error.
    
    Since:
    
    0.13
  - HTTP_CLIENT_HOST
```
public static final TagKey HTTP_CLIENT_HOST
```
    TagKey for the value of the client-side HTTP host header.
    
    Since:
    
    0.13
  - HTTP_SERVER_HOST
```
public static final TagKey HTTP_SERVER_HOST
```
    TagKey for the value of the server-side HTTP host header.
    
    Since:
    
    0.13
  - HTTP_CLIENT_STATUS
```
public static final TagKey HTTP_CLIENT_STATUS
```
    TagKey for the numeric client-side HTTP response status code (e.g. 200, 404, 500). If a transport error occurred and no status code was read, use "error" as the TagValue.
    
    Since:
    
    0.13
  - HTTP_SERVER_STATUS
```
public static final TagKey HTTP_SERVER_STATUS
```
    TagKey for the numeric server-side HTTP response status code (e.g. 200, 404, 500). If a transport error occurred and no status code was written, use "error" as the TagValue.

public static final TagKey HTTP_CLIENT_PATH
```
    TagKey for the client-side URL path (not including query string) in the request.
