Standard Log Format (HTTP)
About the Format
Standard Log Format is a basic log format compatible with Apache Common Log Format (CLF) in terms of field layout. It takes place in the Line Format list in the profile form with the Standard Log Format option.
This format records the basic information of HTTP requests in a compact way. Thanks to its simple structure, it provides low resource consumption and is compatible with most log analysis tools.
Use cases
- Basic access logging requirements.
- Environments where low log volume is desired.
- Integration with systems expecting Apache log format.
Supported Features
HTTP vService
L7 TCP vService
WAF Information
SSL Information
WARNING
If this format is assigned to an L7 TCP vService, the line silently turns into the Standard (L7 TCP) format.
Example Log
text
172.16.101.42 - - [09/Sep/2026:17:36:18 +0000] "GET /login.php HTTP/1.1" 200 1011Field Descriptions
| Field | Example Value | Description |
|---|---|---|
| Client IP | 172.16.101.42 | The client IP address |
| Ident | - | RFC 1413 ident information; it is not filled under any condition in this format. |
| User | - | The HTTP Auth username; it is not carried in this format. |
| Timestamp | 09/Sep/2026:17:36:18 +0000 | The time at which the request was received (GMT) |
| Request Line | "GET /login.php HTTP/1.1" | The HTTP request line (method, path, version); it is enclosed in double quotes |
| Status Code | 200 | The HTTP response status code |
| Bytes | 1011 | The total size of the response served to the client (bytes). The response headers are also included in this number; for this reason the value is greater than the Content-Length header. |
The client IP address changes with Trusted Proxy
If a Trusted Proxy profile is assigned to the vService, the Client IP field carries the real client address resolved from the header defined in the profile instead of the address of the proxy. If no profile is assigned, the address of the side that connects to TR7, that is, the outgoing address of the proxy/CDN, appears in the field.
Request Line Detail
The Request Line consists of three components:
| Component | Example Value | Description |
|---|---|---|
| Method | GET | The HTTP method (GET, POST, PUT, DELETE, etc.) |
| Path | /login.php | The requested URI |
| Version | HTTP/1.1 | The HTTP protocol version |
