+# logging
+## beats, elasticsearch, kibana
+
+jeez...
+
+beats collects logs and sends them to logstash
+(fluentd or fluentbit would be an elternative)
+
+logstash is the database that stores the data
+
+elasticsearch is the search engine for the data
+
+kibana is the web interface for elasticsearch
+
+there are multiple ways to deploy all of that
+the most k8 way is ECK (elastic cloud on kubernetes)
+ECK is a operator and CRDs (like rook)
+it includes crds for beats, elasticsearch and kibana
+
+BUT NOT LOGSTASH!
+ logstash might not be needed if one uses filebeat (part of beats) ???
