+#                             Prometheus configuration file path.
+#  --web.listen-address="0.0.0.0:9090"
+#                             Address to listen on for UI, API, and telemetry.
+#  --web.read-timeout=5m      Maximum duration before timing out read of the
+#                             request, and closing idle connections.

+#  --web.external-url=<URL>   The URL under which Prometheus is externally

+#                             itself. If the URL has a path portion, it will
+#                             be used to prefix all HTTP endpoints served by
+#                             Prometheus. If omitted, relevant URL components
+#                             will be derived automatically.
+#  --web.route-prefix=<path>  Prefix for the internal routes of web endpoints.

+#  --storage.tsdb.use-lockfile
+#                             Create a lockfile in data directory.
+#  --alertmanager.notification-queue-capacity=10000
+#                             The capacity of the queue for pending alert
+#                             manager notifications.
+#  --alertmanager.timeout=10s
