Named for the HTTP method and matched route, or just the method if no route matches. Incoming ``traceparent`` headers are extracted using the global propagator to continue the caller's trace. Incoming ``baggage`` is not propagated into plugin or downstream context in this release. Set ``OTEL_PROPAGATORS=none`` to disable extraction. For public instances, strip trace context headers at your proxy if callers should not supply trace context. - - Kind: ``SERVER``. - - Attributes: - - - ``http.request.method`` - The HTTP request method. Methods outside the nine defined by RFC 9110 and RFC 5789 are recorded as ``_OTHER``. - - ``http.route`` *(optional)* - The regular expression for the matched route, for example ``/(?P[^\/\.]+)/(?P
      [^\/\.]+)(\.(?P\w+))?$`` for a table page. Use this attribute to group requests by route. Omitted when no route matches. - - ``url.path`` - The URL path, excluding the query string. - - ``url.scheme`` - ``http`` or ``https``. - - ``server.address`` *(optional)* - The ``Host`` header, including any ``:port`` suffix. This value is supplied by the client. - - ``user_agent.original`` *(optional)* - The ``User-Agent`` header, verbatim. Omitted if the client sent none. - - ``http.response.status_code`` *(optional)* - The HTTP response status code. Omitted if no response was started. - - ``error.type`` *(optional)* - The exception class name for a failed operation. On HTTP spans, also set to the status code as a string for 5xx responses. A 4xx response alone does not set this attribute or an error status. - - ``datasette.internal_client`` *(optional)* - ``True`` for requests made through ``datasette.client``. Calls made inside another request produce a nested ``SERVER`` span. Filter on this attribute to exclude internal requests from request counts. Omitted for requests received over the network. - -``db.query`` - A SQL operation, including time spent queued for a worker thread. For ``block=False`` writes, the span ends after the write is queued. Callback methods record ``datasette.callback`` in place of ``db.query.text``. - - Kind: ``CLIENT``. - - Attributes: - - - ``db.system`` - Always ``sqlite``. - - ``db.namespace`` - Name of the database being queried. - - ``db.query.text`` *(optional)* - The SQL, truncated to 2048 characters. Bound parameter values are not recorded. For callback methods, ``datasette.callback`` is recorded instead. - - ``datasette.callback`` *(optional)* - The qualified name of the Python callable passed to ``execute_fn()``, ``execute_write_fn()`` or ``execute_isolated_fn()``, for example ``TableInsertView.post..insert_or_upsert_rows``. Set instead of ``db.query.text``. Lambdas appear as ````; use a named function for a more descriptive span. - - ``db.operation.name`` *(optional)* - The statement's leading keyword, such as ``SELECT``, ``INSERT`` or ``CREATE``, if it matches the supported allowlist. Statements beginning with a common table expression report ``WITH``. Omitted for unrecognized keywords and ``execute_write_script()``. - - ``datasette.param_count`` *(optional)* - Number of bound parameters. Recorded instead of the values themselves. - - ``datasette.param_sets`` *(optional)* - Number of parameter sets consumed by ``execute_write_many()``. The parameter values are not recorded. - - ``datasette.time_limit_ms`` *(optional)* - Time limit applied to the read query, in milliseconds: :ref:`setting_sql_time_limit_ms` or a shorter ``custom_time_limit``. - - ``datasette.rows_returned`` *(optional)* - Number of rows returned by a successful read query. - - ``datasette.truncated`` *(optional)* - True if the result was cut short by :ref:`setting_max_returned_rows`. - - ``datasette.interrupted`` *(optional)* - True if the query exceeded its time limit. The span status is set to ``ERROR`` unless the caller used a ``custom_time_limit`` shorter than :ref:`setting_sql_time_limit_ms`, in which case the status is left unset. - - ``datasette.sql_error_suppressed`` *(optional)* - True for a non-timeout SQL error with ``log_sql_errors=False``.
