+ * Complex scripted Logstash dashboard
+ * This script generates a dashboard object that Kibana can load. It also takes a number of user
+ * supplied URL parameters, none are required:
+ *
+ * index :: Which index to search? If this is specified, interval is set to 'none'
+ * pattern :: Does nothing if index is specified. Set a timestamped index pattern. Default: [logstash-]YYYY.MM.DD
+ * interval :: Sets the index interval (eg: day,week,month,year), Default: day
+ *
+ * split :: The character to split the queries on Default: ','
+ * query :: By default, a comma seperated list of queries to run. Default: *
+ *
+ * from :: Search this amount of time back, eg 15m, 1h, 2d. Default: 15m
+ * timefield :: The field containing the time to filter on, Default: @timestamp
+ *
+ * fields :: comma seperated list of fields to show in the table
+ * sort :: comma seperated field to sort on, and direction, eg sort=@timestamp,desc
