This means that it will write whatever data you have specified in the output into an indices named based on the logs field Logs.NET field with a dash and the date. for example if I had logs with the field of Logs.NET = "importantApp" it would write the logs into and indices with the pattern importantApp-2021.04.19 if there were other logs coming in with Logs.NET = "unimportantApp" it would write the logs into and indices with the pattern unimportantApp-2021.04.19
