I have two locations and soon multiples will be added. Since elastic stack by default does not have multitenanacy I am planning to install multiple logstash instances at every location which eventually will gather the data in same elastic instance. Assuming I have LOC-A and LOC-B with logstash-loc-A and logstash-loc-B installed respectively how do I create different indexes for those locations and then create the different dashboards accordingly? I need to keep those completely separate. May be tagging will help?
