+# netdata configuration for aggregating data from remote hosts

+# API keys authorize a pair of sending-receiving netdata servers.
+# Once their communication is authorized, they can exchange metrics for any
+# number of hosts.
+#
+# You can generate API keys, with the linux command: uuidgen

+#    You can have one API key per slave, or the same API key for all slaves.
+#
+#    All options below are used in this order:
+#
+#    a) MACHINE_GUID (settings for each machine)
+#    b) API_KEY      (settings for the API key)
+#    c) this netdata defaults (as in netdata.conf)
+#
+#    You can combine the above (the more specific setting will be used).

+# API key authentication
+# If the key is not listed here, it will not be able to connect.
+
+[API_KEY]
+    # Default settings for the API key
+
+    # You can disable the API key, by setting this to: no
+    # The default (for unknown API keys) is also: no
+    enabled = no
+
+    # The default history in entries, for all hosts using this API key.
+    # You can also set it per host below.
+    # If you don't set it here, the history size of the central netdata
+    # will be used
+    default history = 3600
+
+    # The default memory mode to be used for all hosts using this API key.
+    # You can also set it per host below.
+    # If you don't set it here, the memory mode of netdata.conf will be used.
+    # Valid modes:
+    #    save    save on exit, load on start
+    #    map     like swap (continuously syncing to disks)
+    #    ram     keep it in RAM, don't touch the disk
+    #    none    no database (passing through this netdata)
+    default memory mode = ram

+    # Shall we enable health monitoring for the hosts using this API key?
+    # 3 values:
+    #    yes     enable alarms
+    #    no      do not enable alarms
+    #    auto    enable alarms, only when the sending netdata is connected
+    # You can also set it per host, below.
+    # The default is the same as to netdata.conf
+    health enabled by default = auto
+
+    # postpone alarms for a short period after the sender is connected
+    default postpone alarms on connect seconds = 60
