+=====================
+Logging in production
+=====================
+
+Structured logging with JSON
+============================
+
+For log analysis it is frequently useful to have the logs in a structured
+format.
+
+By installing ``python-json-logger`` (for instance via ``pip install
+python-json-logger`` or ``pip install ".[jsonlogging]"``) and setting up
+a logging formatter like this:
+
+::
+
+    "formatters": {
+        ..
+        "json": {
+            "()": "pythonjsonlogger.json.JsonFormatter",
+            "format": "asctime,levelname,name,message",
+            "style": ",",
+        },
+        ..
+    },
+    "handlers": {
+        "json": {
+            "class": "logging.StreamHandler",
+            "formatter": "json",
+        },
+    },
+
+... the logs produced by argus will be in JSON format.
+
+See `Python logging LogRecord attributes
+<https://docs.python.org/3/library/logging.html#logrecord-attributes>`_ for
+other default keywords useful to put in the "format"-line. "message" is
+a human-chosen plaintext explicitly written in the code and should always be
+included.
