+# node.name: test
+#
+# If omitted the node name will default to the machine's host name
+#
+# ------------ Data path ------------------
+#
+# Which directory should be used by logstash and its plugins
+# for any persistent needs. Defaults to LOGSTASH_HOME/data
+#
+path.data: /var/lib/logstash
+#
+# ------------ Pipeline Settings --------------

+# The ID of the pipeline.
+#
+# pipeline.id: main
+#
+# Set the number of workers that will, in parallel, execute the filters+outputs

+#
+# pipeline.unsafe_shutdown: false

+# config.string:
+#

+# The simple way to see this is to prepend each `name` with a `-`, and keep
+# all associated variables under the `name` they are associated with, and

+# ------------ Cloud Settings ---------------

+# Format of cloud.id is a base64 value e.g. dXMtZWFzdC0xLmF3cy5mb3VuZC5pbyRub3RhcmVhbCRpZGVudGlmaWVy

+# Default is path.data/queue
+#
+# path.queue:

+#
+# If using queue.type: persisted, the total capacity of the queue in number of bytes.
+# If you would like more unacked events to be buffered in Logstash, you can increase the
+# capacity using this setting. Please make sure your disk drive has capacity greater than
+# the size specified here. If both max_bytes and max_events are specified, Logstash will pick
+# whichever criteria is reached first
