Greetings all. I have some questions in general about when beats upgrade. We have ELK running on a cluster where an orchestration platform upgrades the beats automatically. So using Logstash of course when I first used a beat I had to stop Logstash and inject the index templates by hand. My question is do we need to do this process each time the beat is updated? Say I upgraded to Metricbeat 7.9 and through the command line injected the index templates into ES after stopping Logstash. When the beat upgrades to 7.10 do I need to do that again? Does the index structure (mapping) change when beats upgrade? I keep seeing with the beats that there is this 3-4 lag in Kibana between when stuff is supposedly getting ingested and when it shows up in Kibana. Wonder if this is related. Also, I notice if I delete an index pattern after a beat upgrade, and then make a new one, the new "metricbeat-\*" pattern now has mapping conflicts. This is an EXTREMELY confusing situation. Just saying. Thanks! ---

It'd be better to do it, so you know you are always running the latest templates. Otherwise you may get caught out. ---

Adding that I think that beats are automatically upgrading the templates but only when directly connected to Elasticsearch. It does not happen when connected through Logstash. ---
