 * Before the default settings scraped the logs from the individual nodes.  It still does this but now the app forwards to fluent on its own.  Fluent in turn flows to OpenSearch.

+## Curate the Logs

+Opensearch allows us to delete after X number of days

+## Make a Dashboard
+
+In Discover we can save our search with 
+
+```
+logger_name:myapp
+```
+We can then do `Save` to save this search.  We can then add this to a dashboard, or use it to quickly look back to.
