-# Request log format
-
-HTTP request logs are written by synapse (see [`site.py`](../synapse/http/site.py) for details).
-
-See the following for how to decode the dense data available from the default logging configuration.

-| Part | Explanation |
-| ----- | ------------ |
-| AAAA | Timestamp request was logged (not received) |
-| BBBB | Logger name (`synapse.access.(http\|https).<tag>`, where 'tag' is defined in the `listeners` config section, normally the port) |
-| CCCC | Line number in code |
-| DDDD | Log Level |
-| EEEE | Request Identifier (This identifier is shared by related log lines)|
-| FFFF | Source IP (Or X-Forwarded-For if enabled) |
-| GGGG | Server Port |
-| HHHH | Federated Server or Local User making request (blank if unauthenticated or not supplied).<br/>If this is of the form `@aaa:example.com|@bbb:example.com`, then that means that `@aaa:example.com` is authenticated but they are controlling `@bbb:example.com`, e.g. if `aaa` is controlling `bbb` [via the admin API](https://matrix-org.github.io/synapse/latest/admin_api/user_admin_api.html#login-as-a-user). |
-| IIII | Total Time to process the request |
-| JJJJ | Time to send response over network once generated (this may be negative if the socket is closed before the response is generated)|
-| KKKK | Userland CPU time |
-| LLLL | System CPU time |
-| MMMM | Total time waiting for a free DB connection from the pool across all parallel DB work from this request |
-| NNNN | Total time waiting for response to DB queries across all parallel DB work from this request |
-| OOOO | Count of DB transactions performed |
-| PPPP | Response body size |
-| QQQQ | Response status code<br/>Suffixed with `!` if the socket was closed before the response was generated.<br/>A `499!` status code indicates that Synapse also cancelled request processing after the socket was closed.<br/> |
-| RRRR | Request |
-| SSSS | User-agent |
-| TTTT | Events fetched from DB to service this request (note that this does not include events fetched from the cache) |
-
-
-MMMM / NNNN can be greater than IIII if there are multiple slow database queries
-running in parallel.
-
-Some actions can result in multiple identical http requests, which will return
-the same data, but only the first request will report time/transactions in
-`KKKK`/`LLLL`/`MMMM`/`NNNN`/`OOOO` - the others will be awaiting the first query to return a
-response and will simultaneously return with the first request, but with very
-small processing times.
